| 1 | Biomass carbon stocks in China's forests between 2000 and 2050:A prediction based on forest biomass-age relationships显示文摘China's forests are characterized by young forest age,low carbon density and a large area of planted forests,and thus have high potential to act as carbon sinks in the future.Using China's national forest inventory data during 1994-1998 and 1999-2003,and direct field measurements,we investigated the relationships between forest biomass density and forest age for 36 major forest types.Statistical approaches and the predicted future forest area from the national forestry development plan were applied to estimate the potential of forest biomass carbon storage in China during 2000-2050.Under an assumption of continuous natural forest growth,China's existing forest biomass carbon(C) stock would increase from 5.86 Pg C(1 Pg=1015 g) in 1999-2003 to 10.23 Pg C in 2050,resulting in a total increase of 4.37 Pg C.Newly planted forests through afforestation and reforestation will sequestrate an additional 2.86 Pg C in biomass.Overall,China's forests will potentially act as a carbon sink for 7.23 Pg C during the period 2000-2050,with an average carbon sink of 0.14 Pg C yr-1.This suggests that China's forests will be a significant carbon sink in the next 50 years. | XU Bing,GUO ZhaoDi,PIAO ShiLong & FANG JingYun* Department of Ecology,College of Urban and Environmental Sciences,and Key Laboratory for Earth Surface Processes of the Ministry of Education,Peking University,Beijing 100871,China | 2010 | Science China(Life Sciences)2010，53，7： | 61 |
| 2 | THE EAST ASIA/PACIFIC PATTERN TELECONNECTION OF SUMMER CIRCULATION AND CLIMATE ANOMALY IN EAST ASIA显示文摘In this paper,many observations show that the thermal states including the SST,the convective activities in the west-ern Pacific warm pool largely influence the interannual and intraseasonal variations of summer circulation and the cli-mate anomalies in East Asia.Moreover,it is pointed out that there is a teleconnection pattern of summer circulationanomalies in the Northern Hemisphere,the so-called East Asia/Pacific pattern.The cause of the teleconnection pattern is studied by using the theory of quasi-stationary planetary wave propaga-tion,and it may be due to the propagation of quasi-stationary planetary waves forced by heat source around thePhilippines.Moreover,this pattern is well simulated by using a quasi-geostrophic,linear,spherical model and theIAP-GCM,respectively. | 黄荣辉 | 1992 | Acta meteorologica Sinica1992，6，1： | 58 |

| 4 | Carbon density and distribution of six Chinese temperate forests显示文摘Quantifying forest carbon(C) storage and distribution is important for forest C cycling studies and terrestrial ecosystem modeling.Forest inventory and allometric approaches were used to measure C density and allocation in six representative temperate forests of similar stand age(42-59 years old) and growing under the same climate in northeastern China.The forests were an aspen-birch forest,a hardwood forest,a Korean pine plantation,a Dahurian larch plantation,a mixed deciduous forest,and a Mongolian oak forest.There were no significant differences in the C densities of ecosystem components(except for detritus) although the six forests had varying vegetation compositions and site conditions.However,the differences were significant when the C pools were normalized against stand basal area.The total ecosystem C density varied from 186.9 tC hm-2 to 349.2 tC hm-2 across the forests.The C densities of vegetation,detritus,and soil ranged from 86.3-122.7 tC hm-2,6.5-10.5 tC hm-2,and 93.7-220.1 tC hm-2,respectively,which accounted for 39.7% ± 7.1%(mean ± SD),3.3% ± 1.1%,and 57.0% ± 7.9% of the total C densities,respectively.The overstory C pool accounted for > 99% of the total vegetation C pool.The foliage biomass,small root(diameter < 5mm) biomass,root-shoot ratio,and small root to foliage biomass ratio varied from 2.08-4.72 tC hm-2,0.95-3.24 tC hm-2,22.0%-28.3%,and 34.5%-122.2%,respectively.The Korean pine plantation had the lowest foliage production efficiency(total biomass/foliage biomass:22.6 g g-1) among the six forests,while the Dahurian larch plantation had the highest small root production efficiency(total biomass/small root biomass:124.7 g g-1).The small root C density decreased with soil depth for all forests except for the Mongolian oak forest,in which the small roots tended to be vertically distributed downwards.The C density of coarse woody debris was significantly less in the two plantations than in the four naturally regenerated forests.The variability of C allocation patterns in a specific forest is jointly influenced by vegetation type,management history,and local water and nutrient availability.The study provides important data for developing and validating C cycling models for temperate forests. | ZHANG QuanZhi & WANG ChuanKuan* College of Forestry,Northeast Forestry University,Harbin 150040,China | 2010 | Science China(Life Sciences)2010，53，7： | 36 |

| 6 | Geological constraints of giant and medium-sized gas fields in Kuqa Depression显示文摘There is a gas-rich and well-charged petroleumsystem in the Kuqa Depression where Triassic and Jurassicsource rocks play important roles. Distributed in an area ofmore than 10000 km and with a thickness of up to 1000 m,they are composed of dark mudstones, carbonaceous mud-stones and coal seams containing 6%, 40% and 90% of TOC,respectively, and are mainly the humic organic matter. Ashigh-quality regional cap rocks, the Neogene and Eogenegypsum rocks and gypseous mudstones matched well withthe underlying Neogene and Cretaceous-Eogene sandstones.They have formed the most favorable reservoir-seal assem-blages in the Kuqa Depression. Also the Jurassic sandstonesand mudstones formed another favorable reservoir-seal as-semblage. The traps are shaped late in the fold-thrust belt,mainly fixed in the Tertiary-Quaternary, where ten structurestyles have been distinguished. These traps spread as a zonein N-S, are scattered like a segmental line in W-E and showtier-styled vertically. The best traps are gypsum-salt coveredfault-bend anticlines related to the passive roof duplex. Thispetroleum system is characterized by late accumulation. Inthe early Himalayan Movement, mainly gas condensate andoil accumulated and were distributed in the outer circularregion of the kitchen; whereas in the middle and late Hima-layan the gas accumulations mainly formed and were dis-tributed in the inner circular region near the kitchen. Theoverpressure of gas pools is common and is formed by sealcapacity of thick gypsum layers, extensive tectonic compres-sion and large uplift. The well-preserved anticline traps un-derlying the high-quality regional cap rocks of the Tertiarygypsum rocks and gypseous mudstones are the main targetsfor the discovery of giant and medium-sized gas fields. Aboveconclusions are important for the petroleum geology theoryand the exploration of the fold-thrust belt in foreland basinsin central and western China. | JIA Chengzao GU Jiayu ZHANG Guangya | 2002 | Chinese Science Bulletin2002，47，S1： | 17 |
| 7 | Relationship between East Asian winter monsoon, warm pool situation and ENSO cycle显示文摘Based on the observational data analyses and numerical simulations with the air-sea coupled model (CGCM), a new perspective on the occurrence mechanism of ENSO is advanced in this paper. The continuous strong (weak) East Asian winter monsoon will lead to continuous westerly (easterly) wind anomalies over the equatorial western Pacific region. The anomalous equatorial westerly (easterly) winds can cause eastward propagation of the subsurface ocean temperature anomalies (SOTA) in the warm pool region, the positive (negative) SOTA have been in the warm pool region for quite a long time. The eastward propagating of positive (negative) SOTA along the thermocline will lead to positive (negative) SSTA in the equatorial eastern Pacific and the occurrence of El Nino (La Nina) event. After the occurrence of ENSO, the winter monsoon in East Asia will be weak (strong) due to the influence of El Nino (La Nina). | Chongyin Li Mingquan Mu | 2000 | Chinese Science Bulletin2000，45，16： | 17 |
| 8 | Characteristics of China’s oil and gas pool formation in latest geological history显示文摘The structural activities took place extensively in the Asia continent during the Cenozoic era owing to the strong continent-to-continent collision and continuous compression between the India Plate and the Eurasia Plate. Huang Jiqing called such structural activities Himalayan movement. China’s sedimentary basins developed and took shape mainly during the Himalayan movement period. It is also the main period for formation and development of the oil and gas reservoirs. Of 366 large and medium-sized oil and gas fields currently found in China, 212 reservoirs were formed in the Neo- gene-Quaternary period. The proportion is as high as 68.2%. The oil and gas migration and accumu- lation in the latest geological period, which were controlled by the times, properties, styles and strength of the Himalayan movement, took place mainly in eight regions, such as the low uplift area of Bohai Sea, the onshore faulted sag area of Bohai Bay, anticlinorium zone in Daqing, the foreland fold-and-thrust belt in West China, the tilted structural zone in West China, the cratonic palaeohigh in the Tarim Basin, the zone of fault and fold belt in the East Sichuan Basin, and the biological gas zone in the East Qaidam Basin. The oil and gas pool formations in those regions have their own charac- teristics. With the great potential and broad prospect, those regions are the main exploration areas in China in the future. | JIA Chengzao HE Dengfa SHI Xin YANG Geng ZHANG Chaojun | 2006 | Science China Earth Sciences2006，49，9： | 16 |
| 9 | Western Pacific in glacial cycles: Seasonality in marginal seas and variabilities of Warm Pool显示文摘A series of low latitude marginal seas, ranging from the southern South China Sea in the north to the Arafura Sea in the south, are located within the Western Pacific Warm Pool. As shown by micropaleontological, isotopical and organic geochemical analyses, the sea surface temperatures in the marginal seas at the last glacial maximum were much cooler than those in the open Western Pacific Ocean. The emergence of extensive shelves of the marginal seas at the glacial low sea level stand and the decrease of surface temperatures in their deeper water parts resulted in a remarkable reduction of the ability of vapor and heat transport to the atmosphere, causing variabilities to the Warm Pool in the glacial cycles. The intensification of winter monsoon at the glacial stages not only led to a decrease of the surface water temperature and hence to an enhanced seasonality, but also carried moisture from the sea to the tropical islands, giving rise to the downward shift of snowline and mountainous vegetation zones there. It may offer a new alternative in solution of the 'Tropical Ocean Paleo temperature Enigma'. | 汪品先 | 1998 | Science China Earth Sciences1998，41，1： | 14 |

| 11 | Characteristics of carbonate gas pool and multistage gas pool formation history of Hetianhe gas field, Tarim Basin, Northwest China显示文摘Hetianhe is a big carbonate gas field which isfound and demonstrated in the period of 'Chinese NationalNinth 5-Year Plan'. The proved reserve of Hetianhe gas fieldis over 600 ×10~8 m^3. Its main producing layers are Carbon-iferous bioclastic limestone and Ordovician carbonate com-posed of buried hill. The former is stratified gas pool withwater around its side, and the latter is massive gas pool withwater in its bottom. The gases in the gas pools belong to drygases with normal temperature and pressure systems. Basedon the correlation of gas and source rock, the gases aremainly generated from Cambrian source rocks. According tothe researches on source rock and structure evolution, andthe observations on the thin section to reservoir bitumen andthe studies on homogenization temperature of fluid inclu-sions, the gas pool has been identified and divided into threeformation periods. The first is Late Caledonian when the oilgenerated from the Cambrian source rocks and migratedalong faults, as a form of liquid facies into Ordovician carbonate res-ervoir and accumulated there. After that, the crustuplifted, the oil reservoir had been destroyed. The second isLate Hercynian when condensate gases generated from theCambrian source rocks and migrated into Ordovician res-ervoir, as a form of liquid facies. Since the fractures hadreached P strata, so the trap might have a real poor preser-vation condition, and the large-scale gas pool formation hadnot happened. The third gas reservoir formation period oc-curred in Himalaya. The fractures on both sides of Hetianhegas field developed violently under the forces of compression,and thus the present fault horst formed. The dry gases gen-erated from Cambrian source rocks and migrated upwardsas the form of gas facies into Ordovician and Carboniferousreservoirs, and the large gas pool as discovered at presentwas formed finally. | ZHOU Xinyuan JIA Chengzao WANG Zhaoming WANG Qinghua YANG Wei | 2002 | Chinese Science Bulletin2002，47，S1： | 13 |
| 12 | A new type of plunge pool―Multi-horizontal submerged jets显示文摘Based on the understanding of the mechanism of energy dissipation,a new type of plunge pool is presented with the advantages of high rate of energy dissipation,low impact pressure,and small close-to-bed velocity on the soleplate of the plunge pool.The first advantage owes to enlarged shearing energy dissipation areas in the plunge pool,while the other two are caused by the jet that enters in a nearly horizontal level to keep the soleplate from being scoured directly.All of the above arrangements make this new type of energy dissipator distinct from the underflow energy dissipation.Through experiments on the physical model,the authors found that the water flow maintained stable and submerged in horizontal direction when the flow was narrow in horizontal but thick in vertical direction.However,the wide flat nappe was ready to submerge or float as the downstream water level rised or dropped.The entire flow fields of multi-horizontal submerged jets into plunge pool were also numerically simulated.The numerical results of water surface curve,close-to-bed velocity and floor pressure agree well with the experimental data.The flow pattern in the plunge pool was analyzed after combining the laboratory data and numerical simulation. | DENG Jun,XU WeiLin,ZHANG JianMing,QU JinXue & YANG YongQuan State Key Laboratory of Hydraulics and Mountain River Engineering,Sichuan University,Chengdu 610065,China | 2008 | Science China(Technological Sciences)2008，51，12： | 12 |
| 13 | Dynamics for multistage pool formation of Lunnan low uplift in Tarim Basin显示文摘Lunnan area in the Tarim Basin has become animportant onshore oil production base in China. Formationof the oil and gas pools in the low uplift of Lunnan has ex-perienced a comparatively complex process of dynamics.Based on the hydrocarbon generation period of source rocks,the formation period of cap rocks and traps, the analysis oforganic inclusion and the analysis of bitumen in the reservoir,this paper draws the conclusion that the low uplift area ofLunnan has experienced three pool formation periods: thePermian period, the Cretaceous-Early Tertiary period andthe Late Tertiary-Quaternary period and two oil and gasreservoir adjustment periods: the Late Permian period andthe Late Tertiary-Quaternary period. The comprehensivestudy indicates that the large-scale Ordovician buried hill,formed in Early Hercynian, became the reservoir during thePermian period, because the Cambrian-Lower Ordovicianoil was discharged laterally into the reservoir along the topof the Ordovician weathering crust from south to north. Thereservoir experienced a complicated process-reconstruc-tion in the end of Permian, adjustment in Cretaceous-EarlyTertiary and re-discharging process in Late Tertiary-Qua-ternary, leading to the early original heavy oil reservoir ofmarine facies and the late original light oil reservoir and gaspool. Carboniferous, Triassic and Jurassic oil and gas reser-voirs result from upward adjustment and re-distribution ofOrdovician oil and gas reservoirs. Of those results, the for-mation of Triassic-Jurassic oil and gas pools came under theinfluence of the northward-tilting structure. The oil and gassourcing from the different hydrocarbon source rock inter-vals vertically migrated into the base unconformity of Trias-sic system. Then the oil and gas migrated laterally fromnorth to south and accumulated into the reservoir. | HE Dengfa JIA Chengzao LIU Shaobo PAN Wenqing WANG Shejiao | 2002 | Chinese Science Bulletin2002，47，S1： | 11 |
| 14 | The Variation of Warm Pool in the Equatorial Western Pacific and Its Impacts on Climate显示文摘The variation of warm pool ocean temperature in the equatorial western Pacific and its impacts on climatic change are studied in the present paper. The SSTs in the warm POol region notonly have seasonal variation but also have interannual variation more clearly; The influence ofanomalies of SST in the warm pool region on the East Asian monsoon is studied with dataanalysis; And the impact of SSTA in the warm pool region on the teleconnection (wave-train) inthe atmospheric circulation is still investigated. The influence of ocean temperature anomalies inthe warm pool subsurface on the occurrence of ENSO is also discussed by using data analysis andmodelling with CGCM. All above-mentioned studies show that the situation of ocean temperaturein the warm pool region in the equatorial western Pacific plays an important role in the global climatic variation. | 李崇银 穆明权 周广庆 | 1999 | Advances in Atmospheric Sciences1999，16，3： | 10 |

| 17 | INFLUENCE OF HEAT CONTENT ANOMALY IN THE TROPICAL WESTERN PACIFIC WARM POOL REGION ON ONSET OF SOUTH CHINA SEA SUMMER MONSOON显示文摘Based on the Scripps/NODC Joint Environmental Data Analysis Center’s data of heat content in upper ocean (1955--1998) and NCEP/NCAR reanalysis data,the relationship between the heat content anomalies in the warm pool area of the western Pacific (WP) and onset of South China Sea summer monsoon (SCSM) is examined.The results show that the warm pool area (WP) is the place where heat content in the tropical upper layer changes with maximum range and which is most obviously influential to South China Sea summer monsoon.Onset of SCSM is very closely related to the heat content anomaly during the previous period (previous winter and spring) of the WP so that the heat content of March to April in the WP area is a very good predictor for onset of SCSM.When the heat content of the WP area is positive,convection center will be located in the South China Sea-western Pacific with strong convection,a positive anomaly of monsoon circulation and Walker circulation will take place and the subtropical high will be weaker and farther east. Positive anomalous monsoon circulation and Walker circulation will be favorable for westerly and southwesterly flows-SCSM breaks off earlier than normal.Otherwise,SCSM comes later than usual.Large-scale anomalous change of monsoon circulation and Walker circulation seems one of the important mechanisms to influence SCSM. | 陈永利 胡敦欣 | 2003 | Acta meteorologica Sinica2003，17，S1： | 8 |
