| 1 | Influence of the impounding process of the Three Gorges Reservoir up to water level 172.5m on water eutrophication in the Xiangxi Bay显示文摘The water level of the Three Gorges Reservoir(TGR) rose to 172.5 m in two stages from September to November,2008.The hydrodynamic parameters and water quality parameters(e.g.flow velocity,temperature,turbidity and nutrient content) had been continuously monitored to reveal the influence of the impounding process of the TGR on the water eutrophication in the Xiangxi Bay(XXB).The maximal daily rise of the water level of the TGR was about 2.38 m.The water exchange between the mainstream(the Changjiang River) and the XXB of the TGR was enhanced by density current,and its main characteristics were a density-stratified flow in different directions.The water exchange reduced the differences of the water quality parameters(for example,temperature,turbidity,nutrient level,pH,etc.) between the mainstream and the XXB during the impounding process.Meanwhile,the water stability index in the mainstream remained small but it was lowered in the XXB.The main causes included the dilution by water of lower concentration of the chlorophyll a(Chl.a) entering from the mainstream,the decline of the water stability,and the increase of suspended silt,which induced the Chl.a to decrease in the XXB during the impounding process.The grade of the water eutrophication changed from middle eutrophic level to mesotrophic state in the process.However,as available nutrients were imported into the XXB from the mainstream during the impounding process the risk of water eutrophication increases in the XXB in the future. | YANG ZhengJian1,LIU DeFu1,JI DaoBin1,2 & XIAO ShangBin1,3 1 College of Civil & Hydroelectric Engineering,China Three Gorges University,Yichang 443002,China 2 School of Water Resources & Hydropower Engineering,Wuhan University,Wuhan 430072,China 3 Institute of Earth Environment,Chinese Academy of Sciences,Xi’an 710075,China | 2010 | Science China(Technological Sciences)2010，53，4： | 58 |
| 2 | The control of syndepositional faulting on the Eogene sedimentary basin fills of the Dongying and Zhanhua sags, Bohai Bay Basin显示文摘The Dongying and Zhanhua sags are the major hydrocarbon exploration and produc- tion subbasins in the Bohai Bay Basin. Integrated analysis of the sedimentary basin fills has shown that the syndepositional faults and their arrangement styles exerted an important influ- ence on the development and distribution of the Eogene depositional systems. The sedimentary filling evolution of the subbasins reflects the general control of the episodic rifting process. The major long-term active normal faults formed a series of paleogeomorphic accident or slopebreak zones that commonly delineated the subsidiary palaeostructural units and the depositional facies tracts and constrained the general distribution of sedimentary facies zones. The central sag boundary fault slopebreak zones usually determined the distribution of the depocenters of ter- restrial clastic depositional systems, particularly the lowstand fans or deltaic depositional sys- tems, and have proven to be the economically important targets for the exploration of subtle sandstone reservoirs. A variety of syndepositional fault arrangement patterns, including the par- allel, en echelon, combo-like, broom-like fault systems and the fault overlap or transfer zones, have been recognized in the subbasins. They generated distinctive geomorphic features and exerted a direct influence on sediment dispersal and sandbody distribution during the Eogene synrift stage. It is the key for the prediction of depositional systems tracts and reservoir sand- stones to investigate the activity and distribution of the fault slopebreak zones and reconstruct the structural paleogeomorphy in different basin filling stages of the basin evolution. | LIN Changsong1, ZHENG Herong2, REN Jianye1, LIU Jingyan1 & Qiu Yigang1 1.

| 3 | Sequence stratigraphic framework and distribution of depositional systems for the Paleogene in Liaodong Bay area显示文摘With a comprehensive geological and geophysical data base,the Paleogene in the Liaodong Bay area,which consists of the Kongdian,Shahejie and Donghying Formations from the base to top,was divided into 4 second-order sequences and 8 third-order sequences based on the characteristics of the se-quence boundaries. Each third-order sequence is subdivided into the lowstand,lake transgressive and highstand systems tracts. The Lowstand systems tract (LST) is mainly composed of progradational parasequence sets,while the lake transgressive systems tract (TST) largely consists of the retrograda-tional parasequence sets and the highstand systems tract (HST) is dominated by the progradational parasequence sets. The main types of depositional systems include the shallow lake,semi-deep lake,deep lake,delta,fan delta,braided fluvial delta and nearshore subaqueous fan. The braided fluvial delta and fan delta depositional systems are mainly confined to the sequences of the lower SEs4-Ek,SEs3 and SEs1+2,while the sequences of SEd3,SEd2 and SEd1 are dominated by the delta and nearshore subaqueous fan depositional systems with the latter being developed at the downthrown side of the basin-bounding fault in each sequence. The evolution of the depositional systems is always con-trolled by the paleo-tectonic setting and the ancient landform in the space and geological time. It is concluded that the most favorable reservoirs are distributed in the Liaoxi low uplift and the central Liaozhong sag. | ZHU XiaoMin1,DONG YanLei1,YANG JunSheng1,ZHANG Qin1,LI DeJiang2,XU ChangGui3 & YU Shui3 1 National Key Laboratory of Petroleum Resources and Prospecting,China University of Petroleum,Beijing 102249,China 2 Research Institute of Petroleum Exploration and Development——Langfang,PetroChina,Langfang 065007,China 3 Technology Department of CNOOC Tianjin Company,Tianjin 300452,China | 2008 | Science China Earth Sciences2008，51，S2： | 11 |
| 4 | Spatial and Seasonal Patterns of Ichthyoplankton Assemblages in the Haizhou Bay and Its Adjacent Waters of China显示文摘Surveys were conducted in five voyages in Haizhou Bay and its adjacent coastal area from March to December 2011 during full moon spring tides. The ichthyoplankton assemblages and the environmental factors that affect their spatial and seasonal patterns were determined. Totally 35 and 12 fish egg and larvae taxa were identified, respectively. Over the past several decades, the egg and larval species composition has significantly changed in Haizhou Bay and its adjacent waters, most likely corresponding with the alteration of fishery resources, which are strongly affected by anthropogenic activities and climate change. The Bray-Curtis dissimilarity index identified four assemblages: near-shore bay assemblage, middle bay assemblage and two closely related assemblages(near-shore/middle bay assemblage and middle/edge of bay assemblage). The primary species of each assemblage principally reflected the spawning strategies of adult fish. The near-shore bay assemblage generally occurred in near-shore bay, with depths measuring <20 m, and the middle bay assemblage generally occurred in the middle of bay, with depths measuring 20 to 40 m. Spatial and seasonal variations in ichthyoplankton in each assemblage were determined by interactions between biological behavioral traits and oceanographic features, particularly the variation of local conditions within the constraint of a general reproductive strategy. The results of Spearman's rank correlation analysis indicated that both fish egg and larval abundance were positively correlated with depth, which is critical to the oceanographic features in Haizhou Bay. | LI Zengguang YE Zhenjiang WAN Rong | 2015 | Journal of Ocean University of China2015，14，6： | 10 |

| 6 | 胍丁胺对大鼠海马CA1区神经元放电的影响显示文摘应用细胞外记录单位放电技术,在大鼠海马脑片上观察了胍丁胺(agmatine,Agm)对CA1区神经元放电的影响。实验结果如下:(1)在47个海马脑片放电单位上灌流Agm(0.1-1.0μmoL/L)2 rain,有38个单位(80.9%)自发放电频率明显降低,且呈剂量依赖性,9个单位(19.1%)无明显的反应;(2)预先用0.2 mmol/L的L-谷氨酸(三-glutamate,L-Glu)灌流12个海马脑片放电单位,有9个单位(75%)放电频率明显增加,表现为癫痫样放电,在此基础上灌流Agm(1.0μmol/L)2 min,其癫痫样放电被抑制;(3)在7个海马脑片放电单位上给予L型钙通道激动剂:Bay K8644(0.1μmoL/L)时,有6个单位(85.7%)放电频率明显增加,另外1个单位(14.3%)无明显变化,再给予Agm(1.0μmol/L)2 min,其放电频率被明显抑制;(4)13个CA1放电单位,灌流50μmol/L-氧化氮合酶(NOS)抑制剂旷NG-nitro-L-arginine methyl ester(L-NAME)5 min后其放电频率明显增加,在此基础上再给予Agm(1.0 μmoL/L)2 min,有11个单位(84.6%)的放电频率被抑制,有2个单位(15.4%)的变化不明显。上述结果提示:胍丁胺能抑制海马CA1区神经元自发放电以及由谷氨酸、Bay K8644和L-NAME诱发的放电,这一抑制效应可能与胍丁胺阻断CA1区锥体细胞上的NMDA受体,并减少钙离子内流有关。 | 王泽民 孙光启 王志安 何瑞荣 | 2003 | 生理学报2003，55，6： | 9 |
| 7 | Seismic tomography of the crust and upper mantle in the Bohai Bay Basin and its adjacent regions显示文摘In the Bohai Bay Basin and its adjacent regions(112°―124°E,34°―42°N),there exists abundant gas-petroleum while modern inter-plate seismic activity is robust.Although the tectonic structure of this region is very complicated,plenty of geological,geophysical and geochemical data and results are obtained through previous researches.On the basis of absorbing previous results,especially various kinds of geological and geophysical results,we collect and process the arrival time of P-wave phases of local events and tele-seismic events recorded by the station within this region from 1978 to 2004,build the responding initial model,and image the velocity structure of the crust and upper mantle of this region via tomography.The perturbation images of various depths and velocity profiles imply that the velocity structure of the crust and upper mantle in the Bohai Bay Basin and its adjacent regions is mainly influenced by the surface tectonic units,and is characterized by 'Stripped along east-west,and zoned along south-north';some large-scaled faults penetrate Moho and lithosphere,and provide the channels for the basic lava or hot mass upwelling from the mantle. | ZHANG Ling LIU JinSong HAO TianYao LIU JianHua XU Yi | 2007 | Science China Earth Sciences2007，50，12： | 8 |
| 8 | Comparison of Two Methods to Assess the Size Structure of Phytoplankton Community Assemblages, in Liaodong Bay, China显示文摘Liaodong Bay is one of the largest semi-enclosed bays located in Bohai Sea,in northeast China.It is an important feeding and spawning place,even wintering and breeding migration base for many marine organisms.The size structure of phytoplankton communities is a key feature of marine ecosystems and can be used as an indicator for algae disaster,but the methods to evalute is still challenging.Here,we compared the size-fractionated chlorophyll-a method with a high-throughout sequencing method in an evaluation of the size structure of phytoplankton assemblages in Liaodong Bay,China,in 2014.The proportion of picophytoplankton was estimated at just 19%according to the results based on size-fractionated chlorophyll-a,which likely represents a severe underestimation.The sequencing method confirmed that many kinds of phytoplankton species appeared in more than one size-fractionated filter membrane,with some even dominating where the filter membrane pore size was greater than the individual phytoplankton size.According to the sequencing method,the phytoplankton assemblages in Liaodong Bay were dominated by picophytoplankton(average proportion=44%),followed by the nanophytoplankton(average 32%),a composition that is more consistent with other studies.The sequencing method provides a more robust way to assess the size structure and taxonomic diversity of marine phytoplankton communities. | SONG Lun WU Jing DU Jing LI Nan WANG Kun WANG Peng | 2019 | Journal of Ocean University of China2019，18，5： | 8 |

| 10 | 1985-2015 年渤海海岸线和围填海的时空变迁研究(英文)显示文摘Extraction and analysis of the shoreline and land reclamation patterns are important for studies on topics such as the dynamics of coastal wetland ecological environments,transportation and exchange of material energy in coastal regions,and recruitment of fishery resources.Spatial-temporal variations in the shoreline and land reclamation in the Bohai Sea were analyzed based on 49 Landsat images of 7 periods from 1985 to 2015.The following conclusions were drawn.(1)The extracted shoreline data based on visual interpretation had high precision,and the shoreline extraction errors could be controlled within the theoretical range.(2)Over the past 30 years,the shoreline of the Bohai Sea has exhibited an average rate of change of 188.47 m/a and an average accretion distance of 3.55×10^3 m toward the sea.The fastest rate of shoreline change occurred in Laizhou Bay(134.78 m/a),followed by Bohai Bay(128.20 m/a)and Liaodong Bay(61.69 m/a).(3)The average rate of reclamation was 3.25×10^4 ha/a in the Bohai Sea,where the total area of aquaculture land,unused land,and salt land exceeded 60%of the total reclamation area.(4)The geometric shape of the bay became increasingly complicated from year to year,and the geometric center of gravity of the bay moved rapidly toward the sea.In addition,the area of the bay showed a significant decreasing trend.Therefore,to protect the function and structure of the ecosystem in coastal regions,we must control the scale and rate of land reclamation in the future. | 丁小松 单秀娟 陈云龙 金显仕 MUHAMMED Forruq Rahman | 2019 | Journal of Geographical Sciences2019，29，12： | 8 |
| 11 | Geological characteristics of shale rock system and shale oil exploration breakthrough in a lacustrine basin:A case study from the Paleogene 1st sub-member of Kong 2 Member in Cangdong sag,Bohai Bay Basin,China显示文摘A deep understanding of the basic geologic characteristics of the fine-grained shale layers in the Paleogene 1 st sub-member of Kong 2 Member(Ek_2~1) in Cangdong sag, Bohai Bay Basin, is achieved through observation of 140 m continuous cores and systematic analysis of over 1 000 core samples from two wells. Basic geological conditions for shale oil accumulation are proposed based on the unconventional geological theory of oil and gas. The shale rock system mainly developed interbedded formation of felsic shale, calcareous and dolomitic shale and carbonates; high quality hydrocarbon source rock formed in the stable and closed environment is the material base for shale oil enrichment; intergranular pores in analcite, intercrystalline pores in dolomite and interlayer micro-fractures make tight carbonate, calcareous and dolomitic shale and felsic shale effective reservoirs, with brittle mineral content of more than 70%; high abundance laminated shale rock in the lower section of Ek_2~1 is rich in shale oil, with a total thickness of 70 m, burial depth between 2 800 to 4 200 m, an average oil saturation of 50%, a sweet spot area of 260 km^2 and predicted resources of over 5×10~8 t. Therefore, this area is a key replacement domain for oil exploration in the Kongdian Formation of the Cangdong sag. At present, the KN9 vertical well has a daily oil production of 29.6 t after fracturing with a 2 mm choke. A breakthrough of continental shale oil exploration in a lacustrine basin is expected to be achieved by volume fracturing in horizontal wells. | ZHAO Xianzheng ZHOU Lihong PU Xiugang JIN Fengming HAN Wenzhong XIAO Dunqing CHEN Shiyue SHI Zhannan ZHANG Wei YANG Fei | 2018 | Petroleum Exploration and Development2018，45，3： | 8 |
| 12 | Wintertime extreme precipitation event over southern China and its typical circulation features显示文摘This study objectively defined an extreme precipitation event(EPE)over southern China and investigated the associated typical circulation pattern on the intraseasonal time scale.The occurrence of the EPE resulted from the joint operations of anomalous circulations over the subtropics and mid-high latitudes.During the EPE,simultaneous enhancements of the trough over the Bay of Bengal(BBT)and the Western Pacific subtropical high(WPSH)facilitated the abundant water vapor conditions over southern China,whereas the weakened East Asian major trough(EAT)led to a moderate cold air invasion to that region,producing a persistent convergence zone over southern China.Wave train pattern in North Atlantic and Europe may be viewed as precursory signals for the EPE over southern China,and it contributed to the Rossby wave propagation in association with the EPE.These wave packets propagated toward East Asia mainly along the North African-Asian subtropical westerly jet waveguide.Low-frequency disturbances along this waveguide contributed to the enhancement of the BBT and WPSH and the weakening of the EAT,constituting favorable circulation conditions for the EPE. | Haifeng Zong Cholaw Bueh Liren Ji | 2014 | Chinese Science Bulletin2014，59，10： | 7 |
| 13 | Sediment distribution and provenance since Late Pleistocene in Laizhou Bay,Bohai Sea,China显示文摘There are three transgression-regression events and evolutions of the sedimentary environment by sea level changes since the Pleistocene in the southern section of the Bohai Sea, China. It is obvious that a multi-source fluvial delta sedimentary system may be more dominant in a sedimentary environment. Based on previous research and survey or historical data, we carried out studies on the division of sedimentary units, sedimentary facies analysis and strata division and comparison, which aim to establish the sedimentary stratigraph of Laizhou Bay. We focus on the sedimentary procession of the Laizhou Bay since the early Late Pleistocene. It can be divided into two glacial periods and three interglacial periods, corresponding to two regression and three transgression events in Laizhou Bay since Late Pleistocene. In 124.6-72.0 ka BP, 60.0-24.4 ka BP and 10.2-4.0 ka BP, three times warm-wet periods occurred, respectively corresponding to the Cangzhou transgression, Xianxian transgression, and Huanghua transgression. In 72.0-60.0 ka BP and 24.4-10.2 ka BP, two dry and cold periods, it was the continental sedimentary environment, corresponding to Wurm early glacier and Wurm late glacier. The results show:(1) Sediments have the characteristics of phase and stage under the terrestrial input of the Yellow River and middle-small rivers in the southern section of the Bohai Sea.(2) PI moved towards coastal in Cangzhou transgression strata in early Late Pleistocene. PI moved northward from land in Xianxian transgression strata in the late Pleistocene. PI moved further north in the Huanghua transgression strata in Holocene.(3) During the regressive period, the land source input increased and the estuarine or lagoon sedimentation developed, which manifested as progradational superposition.(4) During the transgressive period, it mainly developed shallow coastal sediment and transitionally formed regressive deposition to the south in delta/tidal flat deposition. | Mao-sheng Gao Fei Guo Xue-yong Huang Guo-hua Hou | 2019 | China Geology2019，2，1： | 7 |
| 14 | Spatial-temporal variation of phytoplankton community structure in Jiaozhou Bay, China显示文摘To better understand the spatial-temporal variation in phytoplankton community structure and its controlling factors in Jiaozhou Bay, Qingdao, North China, four seasonal sampling were carried out in 2017. The phytoplankton community structure and various environmental parameters were examined. The phytoplankton community in the bay was composed of mainly diatoms and dinofl agellates, and several other species of Chrysophyta were also observed. Diatoms were the most dominant phytoplankton group throughout the year, except in spring and winter, when Noctiluca scintillans was co-dominant. High Si/N ratios in summer and fall refl ect the high dominance of diatoms in the two seasons. Temporally, the phytoplankton cell abundance peaked in summer, due mainly to the high temperatures and nutrient concentrations in summer. Spatially, the phytoplankton cell abundance was higher in the northern part of the bay than in the other parts of the bay in four seasons. The diatom cell abundances show signifi cant positive correlations with the nutrient concentrations, while the dinofl agellate cell abundances show no correlation or a negative correlation with the nutrient concentrations but a signifi cant positive correlation with the stratifi cation index. This discrepancy was mainly due to the diff erent survival strategies between diatoms and dinofl agellates. The Shannon-Wiener diversity index ( H′) values in the bay ranged from 0.08 to 4.18, which fell in the range reported in historical studies. The distribution pattern of H′ values was quite diff erent from that of chlorophyll a , indicating that the phytoplankton community structure might have high biomass with a low diversity index. Compared with historical studies, we believe that the dominant phytoplankton species have been changed in recent years due mainly to the changing environment in the Jiaozhou Bay in recent 30 years. | GUO Shujin ZHU Mingliang ZHAO Zengxia LIANG Junhua ZHAO Yongfang DU Juan SUN Xiaoxia | 2019 | Journal of Oceanology and Limnology2019，37，5： | 6 |

| 16 | Transport Accessibility and Spatial Connections of Cities in the Guangdong-Hong Kong-Macao Greater Bay Area显示文摘Based on geographic information system(GIS) spatial analysis technology, the spatial pattern of raster grid transport accessibility for the Guangdong-Hong Kong-Macao Greater Bay area was studied and the states of spatial connectedness were simulated using highway passenger transport, railway passenger transport, port passenger transport and aviation passenger transport data. The result shows that transport accessibility within the Guangdong-Hong Kong-Macao Greater Bay area costs ‘one hour’ and the spatial distribution of accessibility in the area presents clear ‘core-periphery’ spatial characteristics, with Guangzhou, Foshan, Shenzhen constituting the core. The transport accessibility of Guangdong-Hong Kong-Macao is high. Average accessibility of urban nodes as measured by travel time is 0.99 h, and the areas accessible within 1.42 h occupy 79.14% of the total area. Most of the areas with the lowest accessibility are found in the peripheral area, with the worst accessibility being 4.73 h. Compared with the west-side cities, the economically developed east-side cities of the Guangdong-Hong Kong-Macao Greater Bay area have higher connectivity with roads, railways, ports, and aviation transport. Guangzhou, Foshan, Zhuhai, Shenzhen, Hong Kong and Macao are closely linked. The higher the accessibility, the closer the intercity connectedness. | CAO Xiaoshu OUYANG Shishu YANG Wenyue LUO Yi LI Baochao LIU Dan | 2019 | Chinese Geographical Science2019，29，5： | 6 |
| 17 | Organic Carbon in the Surface Sediments from the Intensive Mariculture Zone of Sanggou Bay: Distribution, Seasonal Variations and Sources显示文摘Mariculture has rapidly grown worldwide, which might greatly influence the biogeochemical cycle of organic carbon in coastal seas. In this study, several geochemical parameters, including grain size composition, sedimentary total organic carbon (TOC), total nitrogen (TN), stable carbon (δ13C) and nitrogen (δ15N) isotopic compositions, were analyzed for surface sediments collected from different mariculture zones of Sanggou Bay and in different seasons. We investigated the composition and distribution of or- ganic matter in surface sediments and further evaluated the contribution of mariculture activities to TOC sources. The TOC and TN contents (mass percentage) in the bay were in the range of 0.14% to 1.45% and 0.03% to 0.20%, respectively. The spatial distribution indicated that sedimentary TOC and TN contents in shellfish monoculture and shellfish-kelp polyculture zones were higher than in other mariculture zones, which might be related to grain size composition and mariculture organisms. Seasonal variations of TOC contents were observed in different mariculture zones. The TOC/TN atomic ratio (C/N),δ13C and δ15N were in the ranges of 5.97 to 10.97, 21.76‰ to 13.14‰ and 2.13‰ to 8.08‰, respectively, implying that sedimentary organic matter in Sanggou Bay was the mixture of marine phytoplankton, terrestrial and maricultural sources. A simple mixing model based on δ13C was applied and the results indicated that the relative contributions of organic carbon sources in Sanggou Bay followed the order kelp (36.6%) marine phytoplankton (28.7%) shellfish bio-deposition (23.8%) terrestrial input (10.9%). Surface sediments in Sanggou Bay were domi- nated by mariculture-derived organic carbon, which on average accounted for 60.4% of TOC. | SUI Juanjuan ZHANG Jihong REN S.

| 19 | Numerical analysis on water exchange and its response to the coastal engineering in the Yueqing Bay in China显示文摘On the basis of a numerical model of tidal current using Delft3D, the distribution of the semi - exchange time of water was simula- ted in the Yueqing Bay here. The result showed that the semi - exchange time was about more than 6 d in the bay end, and about 1~2 d in the bay mouth. Besides, based on the calculation of the semi - exchange time before and after the Xuanmen Dam pro- ject, a comparison between them was further carried out. And the same work was also done with the recent reclamation projects in the Yueqing Bay as well. The results showed that the change in semi - exchange time caused by the Xuanmen Dam project was a- bout 6 d increase near the dam and 4.5 d increase at the bay end. And it was about 5 d increase at the bay end and 1 d increase at the mouth of the bay caused by the recent reclamation projects. | LI Jia YAO Yanming LI Xiaoyan ZHANG Hongwei | 2008 | Acta Oceanologica Sinica2008，27，z1： | 5 |
| 20 | Lagrangian methods for water transport processes in a long-narrow bay-Xiangshan Bay, China显示文摘A better understanding of water transport processes is highly desirable for the exploitation of the ocean resources and the protection of the ocean ecological system.In this paper,the Lagrangian methods are used to study the water transport processes in Xiangshan Bay in China,a typical semi-closed and narrow-shaped bay with complex coastline and topography.A high-resolution3-D hydrodynamic model is developed and verified,and the results from the model agree well with the field data.Based on the hydrodynamic model,the Lagrangian residual current is computed by using the particle tracking method.A concept based on the dynamical systems theory,the Lagrangian coherent structures(LCSs),is introduced to uncover the underlying structures which act as the transport barriers in the flow.The finite-time Lyapunov exponent(FTLE)fields are computed from the hydrodynamic model results to extract the LCSs.The results indicate that the LCSs act as the internal structures of the Lagrangian residual current and the Lagrangian residual current displays the residual current speed and direction of different water regimes separated by the LCSs.The water masses with different transport characteristics can be identified and their exchange ability with other water masses can be estimated by combining the Lagrangian particle tracking with the LCSs methods.The comprehensive applications of these Lagrangian methods reveal the underlying structures and the inhomogeneous characteristics of the water transport in Xiangshan Bay. | 梁书秀 韩松林 孙昭晨 胡展铭 | 2014 | Journal of Hydrodynamics2014，26，4： | 5 |
