| 1 | Restoration and Rational Use of Degraded Saline Reed Wetlands:A Case Study in Western Songnen Plain, China显示文摘The protection, restoration and sustainable use are key issues of all the wetlands worldwide. Ecological, agronomic, and engineering techniques have been integrated in the development of a structurally sound, ecologically beneficial engineering restoration method for restoring and utilizing a degraded saline wetland in the western Songnen Plain of China. Hydrological restoration was performed by developing a system of biannual irrigation and drainage using civil engineering measures to bring wetlands into contact with river water and improve the irrigation and drainage system in the wetlands. Agronomic measures such as plowing the reed fields, reed rhizome transplantation, and fertilization were used to restore the reed vegetation. Biological measures, including the release of crab and fish fry and natural proliferation, were used to restore the aquatic communities. The results of the restoration were clear and positive. By the year 2009, the reed yield had increased by 20.9 times. Remarkable ecological benefits occurred simultaneously. Vegetation primary-production capacity increased, local climate regulation and water purification enhanced, and biodiversity increased. This demonstration of engineering techniques illustrates the basic route for the restoration of degraded wetlands, that the biodiversity should be reconstructed by the comprehensive application of engineering, biological, and agronomic measures based on habitat restoration under the guidance of process-oriented strategies. The complex ecological system including reeds, fish and crabs is based on the biological principles of coexistence and material recycling and provides a reasonable ecological engineering model suitable for the sustainable utilization of degraded saline reed wetlands. | WEN Bolong LIU Xingtu LI Xiujun YANG Fuyi LI Xiaoyu | 2012 | Chinese Geographical Science2012，22，2： | 10 |
| 2 | Optimization of Stocking Density for the Sea Cucumber, Apostichopus japonicus Selenka, Under Feed-Supplement and Non-Feed-Supplement Regimes in Pond Culture显示文摘Optimal stocking densities were investigated for the sea cucumber Apostichopus japonicus Selenka under feed-supplement and non-feed-supplement regimes in net enclosures for 333 d. Substantial weight loss occurred during the aestivation phase (AE). Decreased growth rates were also observed during the winter phase (WT). In contrast, sea cucumbers showed rapid growth during the spring (SP) and autumn (AU) phases. Feeding regimes considerably influenced the growth performance, i.e., sea cucumbers grew faster under feed-supplement regime than under non-feed-supplement regime (P < 0.05). The average survival rates of sea cucumbers under feed-supplement regime were higher than those under non-feed-supplement regime for both the autumn phase and spring phase, but the differences were only significant for the latter phase (P < 0.05). The fitted B-N curves showed that the optimal stocking densities, in terms of net production, were 22.3 ind. m-2 for feed-supplement regime and 14.1 ind. m-2 for non-feed-supplement regime. | QIN Chuanxin DONG Shuanglin TAN Fuyi TIAN Xiangli WANG Fang DONG Yunwei GAO Qinfeng | 2009 | Journal of Ocean University of China2009，8，3： | 10 |
| 3 | Effect of filter-feeding fish silver carp on phytoplankton species and size distribution in surface water:A field study in water works显示文摘Silver carp were introduced into the pre-sedimentation pond to control excessive phytoplankton in raw water.The effectiveness of the filter-feeding silver carp on phytoplankton control and the effect of silver carp on phytoplankton community were investigated.The results showed that Microcystis could be effectively removed by silver carp stocked in the pre-sedimentation pond,and simultaneously,the concentration of single-cell phytoplankton increased obviously.The difference in phytoplankton species and singlecell phytoplankton size between in the water and in the gut of silver carp indicated that phytoplankton smaller than 5 μm,such as Chamydomonas and Platymonas,were almost not be filtered by silver carp,phytoplankton with the size between 5 and 20 μm could be partly filtered,and large size phytoplankton,mainly colony-forming Microcystis could be filtered almost completely.These filterfeeding characteristics directly caused the phytoplankton size distribution biased toward miniaturization.Therefore,this biological treatment using silver carp could be applied only to deal with groups of Microcystis-dominated eutrophic water,and was not appropriate in water bodies where single-cell micro phytoplankton were dominant.Especially when silver carp are used in water treatment,a cautious attitude should be taken based on the evaluation of phytoplankton biomass and species structure features in raw water. | Hua Ma Fuyi Cui Zhiquan Liu Zhenqiang Fan Wenjie He Peijun Yin | 2010 | Journal of Environmental Sciences2010，22，2： | 9 |

| 5 | Evaluation of drinking water treatment combined filter backwash water recycling technology based on comet and micronucleus assay显示文摘Based on the fact that recycling of combined filter backwash water(CFBW)directly to drinking water treatment plants(WTP)is considered to be a feasible method to enhance pollutant removal efficiency,we were motivated to evaluate the genotoxicity of water samples from two pilot-scale drinking water treatment systems,one with recycling of combined backwash water,the other one with a conventional process.An integrated approach of the comet and micronucleus(MN)assays was used with zebrafish(Danio rerio)to investigate the water genotoxicity in this study.The total organic carbon(TOC),dissolved organic carbon(DOC),and trihalomethane formation potential(THMFP),of the recycling process were lower than that of the conventional process.All the results showed that there was no statistically significant difference(P>0.05)between the conventional and recycling processes,and indicated that the genotoxicity of water samples from the recycling process did not accumulate in 15 day continuous recycling trial.It was worth noting that there was correlation between the concentrations of TOC,DOC,UV_(254),and THMFPs in water and the DNA damage score,with corresponding R^2 values of 0.68,0.63,0.28,and 0.64.Nevertheless,both DNA strand breaks and MN frequency of all water samples after disinfection were higher than that of water samples from the two treatment units,which meant that the disinfection by-products(DBPs)formed by disinfection could increase the DNA damage.Both the comet and MN tests suggest that the recycling process did not increase the genotoxicity risk,compared to the traditional process. | Ting Chen Yongpeng Xu Zhiquan Liu Shijun Zhu Wenxin Shi Fuyi Cui | 2016 | Journal of Environmental Sciences2016，28，4： | 8 |
| 6 | Experimental study of photooxidation products of ethylbenzene显示文摘Smog chamber experiments were performed to investigate the composition of products formed from photooxidation of aromatic hydrocarbon ethylbenzene.Vacuum ultraviolet photoionization mass spectrometer and aerosol time-of-flight mass spectrometer were used to measure the products in the gas and particle phases in real-time.Experimental results demonstrated that ethylphenol,methylglyoxal,phenol,benzaldehyde,and 2-ethylfurane were the predominant photooxidation products in both the gas and particle phases.However,there were some dierences between detected gas phase products and those of particle phase,for example,2-ethylfurane,ethylglyoxylic acid,nitroethylbenzene,3,4-dioxopentanal and ethyl-nitrophenol were only existing in the particle-phase. The possible reaction mechanisms leading to these products were also discussed and proposed. | Mingqiang Huang Weijun Zhang Liqing Hao Zhenya Wang Li Fang Ruihong Kong Xiaobin Shan Fuyi Liu Liusi Sheng | 2010 | Journal of Environmental Sciences2010，22，10： | 5 |
| 7 | Pseudocapacitance boosted N-doped carbon coated Fe7S8 nanoaggregates as promising anode materials for lithium and sodium storage显示文摘Herein,the core-shell structured N-doped carbon coated Fe7S8 nano-aggregates(Fe7S8@NC)were controllably prepared via a simple three-step synthesis strategy.The appropriate thickness of N-doped carbon layer outside Fe7S8 nano-aggregates can not only inhibit the particle pulverization induced by the big volume changes of Fe7S8,but can increase the electron transfer efficiency.The hierarchical Fe7S8 nano-aggregates composed of some primary nanoparticles can accelerate the lithium or sodium diffusion kinetics.As anode materials for Li-ion batteries(LIBs),the well-designed Fe7S8@NC nanocomposites exhibit outstanding lithium storage performance,which is better than that of pure Fe7S8,Fe3O4@NC and Fe7S8@C.Among these nanocomposites,the N-doped carbon coated Fe7S8 with carbon content of 26.87 wt.%shows a high reversible specific capacity of 833 mAh·g^−1 after 1,000 cycles at a high current density of 2 A·g^−1.The above electrode also shows excellent high rate sodium storage performance.The experimental and theoretical analyses indicate that the outstanding electrochemical performance could be attributed to the synergistic effect of hierarchical Fe7S8 nanostructure and conductive N-doped carbon layer.The quantitative kinetic analysis indicates that the charge storage of Fe7S8@NC electrode is a combination of diffusion-controlled battery behavior and surface-induced capacitance behavior. | Yanli Zhou Ming Zhang Qi Wang Jian Yang Xingyun Luo Yanlu Li Rong Du Xinsheng Yan Xueqin Sun Caifu Dong Xiaoyu Zhang Fuyi Jiang | 2020 | Nano Research2020，13，3： | 4 |
| 8 | Characterization of the adsorption behavior of aqueous cadmium on nanozero-valent iron based on orthogonal experiment and surface complexation modeling显示文摘Polyvinylpyrrolidone K-30(PVP) was introduced into the preparation of nanozero-valent iron(n ZVI) and the traditional liquid-phase reduction was improved. The introduction of PVP simplified the traditional method.The n ZVI prepared with this new approach showed excellent surface characters and high performance on the removal of cadmium. TEM results showed that the aggregates of n ZVI can reach to several micrometers in length but less than 100 nm in diameter. The iron particles that were enclosed by a layer of oxide film that is less than10 nm, demonstrated that the n ZVI possesses a core–shell structure. BET results indicate that the specific surface area of the n ZVI was 20.3159 m^2g^(-1). A three factor and three level orthogonal experiment was employed to find out the dominant factor that affects the removal rate of cadmium by n ZVI. Based on the range values, the prominence order of each factor was: initial p H of the solution N initial concentration of cadmium N dosage of n ZVI, the range was 96.453, 3.294 and 1.747, respectively. A simulation was performed under the same condition and a same conclusion was derived, this consistence confirmed the validity of the conclusion that p H is the most significant factor that affects the adsorption efficiency. | Dongmei Liu Huan Tang Ying Zhao Fuyi Cui Jing Lu | 2016 | Chinese Journal of Chemical Engineering2016，24，9： | 2 |

| 10 | Horizontal and vertical gene transfer drive sediment antibiotic resistome in an urban lagoon system显示文摘Rapid urbanization has resulted in pervasive occurrence of antibiotic resistance genes(ARGs)in urban aquatic ecosystems.However,limited information is available concerning the ARG profiles and the forces responsible for their assembly in urban landscape lagoon systems.Here,we employed high-throughput quantitative PCR(HT-q PCR)to characterize the spatial variations of ARGs in surface and core sediments of Yundang Lagoon,China.The results indicated that the average richness and absolute abundance of ARGs were 11 and 53 times higher in the lagoon sediments as compared to pristine reference Tibetan lake sediments,highlighting the role of anthropogenic activities in ARG pollution.Co-occurrence network analysis indicated that various anaerobic prokaryotic genera belonging to Alpha-,Deltaproteobacteria,Bacteroidetes,Euryarchaeota,Firmicutes and Synergistetes were the potential hosts of ARGs.The partial least squares-path modeling(PLS-PM)analysis revealed positive and negative indirect effects of physicochemical factors and heavy metals on the lagoon ARG profiles,via biotic factors,respectively.The horizontal(mediated by mobile genetic elements)and vertical(mediated by prokaryotic communities)gene transfer may directly contribute the most to drive the abundance and composition of ARGs,respectively.Furthermore,the neutral community model demonstrated that the assembly of sediment ARG communities was jointly governed by deterministic and stochastic processes.Overall,this study provides novel insights into the diversity and distribution of ARGs in the benthic habitat of urban lagoon systems and underlying mechanisms for the spread and proliferation of ARGs. | Hongjie Wang Liyuan Hou Yongqin Liu Keshao Liu Lanping Zhang Fuyi Huang Lin Wang Azhar Rashid Anyi Hu Changping Yu | 2021 | Journal of Environmental Sciences2021，33，4： | 2 |
| 11 | Characteristics of fat metabolism in skeletal muscle of rats after hypobaric hypoxic acclimation显示文摘Objective: To investigate the characteristics of fat metabolism in rat skeletal muscle after hypobaric hypoxia acclimation. Methods: Sprague-Dawley rats were divided into 3 groups randomly: control group (H0), hypoxic 5-day group (H5), and hypoxic 15-day group (H15). Animals of H5 and 15 groups were exposed to hypobaric hypoxia chamber simulating 5 000 m high altitude for 5 d or 15 d respectively, 23 h per day. H0 group stayed outside of chamber. The level of fatty acid oxidation and uptake, and glucose oxidation were examined, and the level of non-esterified fatty acids (NEFA), ATP and phosphocreatine (PCr) were also assayed in rat skeletal muscles. Results: The contents of ATP and PCr in H5 group were lower than those in H0 and H15 groups (P<0.05), while there was no significant difference between H0 and H15. Compared with H0, the blood NEFA level in all hypoxia groups was increased significantly (P<0.05). The muscle NEFA level in H15 group was greatly higher than that in H0 and H5 groups. The rates of fatty acid oxidation and uptake in H15 group were significantly higher than those in H0 and H5 groups (P<0.05), and the rate of glucose oxidation in all hypoxia groups was significantly decreased than that in H0 group (P<0.05). Conclusion: It is concluded that the enhanced fat oxidation may be one of the mechanisms in the maintenance of energy homeostasis after hypobaric hypoxic acclimation. | Mao Sunzhong Gao Yuqi Chen Jian Liu Fuyi Gao Wenxiang Huang Jian Liao Weigong Cai Mingchun | 2008 | Journal of Medical Colleges of PLA(China)2008，23，5： | 2 |
