| 1 | Current status and future tendency of lake eutrophication in China显示文摘Current trophic status and trend of Chinese freshwater lakes were investigated in this study. The results showed that all lakes studied were commonly undergoing the eutrophication process, water quality decreased and lake's ecosystem is being declined. Most of the urban lakes are facing serious eutrophication. Many medium-sized lakes are in metrophic or eutrophic status, some local water are even approaching the hypertrophic level. The famous five freshwater lakes in China have entered into eutrophication in the condition of higher nutrient load. Lake Taihu, Hongze and Caohu are already in eutrophic state. Eutrophic lakes are mainly distributed in the middle and lower reaches of Yangtze River and Yungui plateau. Lake eutrophication developed rapidly. Among the 34 lakes studied in 1970's, most of lakes were in the mesotrophic status,mesotrophic water area accounted for 91.8%. With the nine year of 1978-1987 the area percentage of oligotrophic lakes decreased from 3.2% to 0.53%, and that of eutrophic lakes increased from 5.0% to 55.01%. Recent data showed 57.5% lakes were in eutrophic and hypertrophic status of the 40 surveyed lakes.Eutrophic trend of Lake Taihu, Chaohu and Xuanwu in the region of the middle and lower reaches of Yangtze River was predicated using the ecological stress model. The results showed that in 2008 Lake Taihu, Chaohu and Xuanwu might be of eutrophication, eutrophication and hypertrophication, respectively if no control measurement is taken. Provided the pollution water treatment rate is 60% in 2030, approximately 30 billion ton pollution water would still be discharged directly in the lakes. Therefore, in 2030 the urban lakes in China might be eutrophication or hypertrophication, and most of the medium-sized lakes at the urban-rural fringe might be in eutrophication or hypertrophication. The famous five biggest freshwater lakes in China might be eutrophication if control countermeasures are taken as now.Lake eutrophication has become a serious environmental problem in China. Based on the domestic and foreign experiences of the eutrophic control technologies, both nutrient pollution control and lake ecological restoration should be carried out and this may be the guidance for the eutrophic control of lakes in China. | JIN Xiangcan, XU Qiujin & HUANG Changzhu Chinese Research Academy of Environmental Sciences, Beijing 100012, China | 2005 | Science China(Life Sciences)2005，48，z2： | 68 |
| 2 | Contaminant removal from low-concentration polluted river water by the bio-rack wetlands显示文摘The bio-rack is a new approach for treating low-concentration polluted river water in wetland systems.A comparative study of the efficiency of contaminant removal between four plant species in bio-rack wetlands and between a bio-rack system and control system was conducted on a small-scale (500 mm length × 400 mm width × 400 mm height) to evaluate the decontamination effects of four different wetland plants.There was generally a significant difference in the removal of total nitrogen (TN),ammonia nitrogen (NH 3-N) and total phosphorus (TP),but no significant difference in the removal of permanganate index (COD Mn) between the bio-rack wetland and control system.Bio-rack wetland planted with Thalia dealbata had higher nutrient removal rates than wetlands planted with other species.Plant fine-root (root diameter 3 mm) biomass rather than total plant biomass was related to nutrient removal efficiency.The study suggested that the nutrient removal rates are influenced by plant species,and high fine-root biomass is an important factor in selecting highly effective wetland plants for a bio-rack system.According to the mass balance,the TN and TP removal were in the range of 61.03-73.27 g/m2 and 4.14-5.20 g/m2 in four bio-rack wetlands during the whole operational period.The N and P removal by plant uptake constituted 34.9%-43.81% of the mass N removal and 62.05%-74.81% of the mass P removal.The study showed that the nitrification/denitrification process and plant uptake process are major removal pathways for TN,while plant uptake is an effective removal pathway for TP. | Ji Wang Lanying Zhang Shaoyong Lu Xiangcan Jint Shu Gan | 2012 | Journal of Environmental Sciences2012，24，6： | 4 |
| 3 | Resolving the influence of nitrogen abundances on sediment organic matter in macrophyte-dominated lakes, using fluorescence spectroscopy显示文摘A controlled experiment was designed to resolve the influence of nitrogen abundance on sediment organic matters in macrophyte-dominated lakes using fluorescence analysis.Macrophyte biomass showed coincident growth trends with time, but different variation rates with nitrogen treatment. All plant growth indexes with nitrogen addition(N, NH4Cl100, 200, 400 mg/kg, respectively) were lower than those of the control group. Four humiclike components, two autochthonous tryptophan-like components, and one autochthonous tyrosine-like component were identified using the parallel factor analysis model. The results suggested that the relative component changes of fluorescence in the colonized sediments were in direct relation to the change of root biomass with time. In the experiment, the root formation parameters of the plants studied were significantly affected by adding N in sediments, which may be related to the reason that the root growth was affected by N addition.Adding a low concentration of N to sediments can play a part in supplying nutrients to the plants. However, the intensive uptake of NH4+may result in an increase in the intracellular concentration of ammonia, which is highly toxic to the plant cells. Hence, our experiment results manifested that organic matter cycling in the macrophyte-dominated sediment was influenced by nitrogen enrichment through influencing vegetation and relevant microbial activity. | Xin Yao Shengrui Wang Lixin Jiao Caihong Yan Xiangcan Jin | 2015 | Journal of Environmental Sciences2015，27，1： | 3 |
| 4 | Control concept and countermeasures for shallow lakes’eutrophication in China显示文摘Research on lake eutrophication in China began in the early 1970s,and many lakes in China are now known to be in meso-eutrophic status.Lake eutrophication has been showing a rapidly increasing trend since 2000.Investigations show that the main reasons for lake eutrophication include a fragile lake background environment,excessive nutrient loading into lakes,excessive human activities,ecological degeneration,weak environmental protection awareness,and lax lake management.Major mechanisms resulting from lake eutrophication include nutrient recycling imbalance,major changes in water chemistry(pH,oxygen,and carbon),lake ecosystem imbalance,and algal prevalence in lakes.Some concepts for controlling eutrophication should be persistently proposed,including lake catchment control,combination of pollutant source control with ecological restoration,protection of three important aspects(terrestrial ecology,lake coast zone,and submerged plant),and combination of lake management with regulation.Measures to control lake eutrophication should include pollution source control(i.e.,optimize industrial structural adjustments in the lake catchment,reduce nitrogen and phosphorus emission amounts,and control endogenous pollution)and lake ecological restoration(i.e.establish a zone-lake buffer region and lakeside zone,protect regional vegetation,utilize hydrophytes in renovation technology);countermeasures for lake management should include implementing water quality management,identifying environmental and lake water goals,legislating and formulating laws and regulations to protect lakes,strengthening publicity and the education of people,increasing public awareness through participation in systems and mechanic innovations,establishing lake region management institutions,and ensuring implementation of governance and management measures. | Xiangcan JIN Shaoyong LU Xiaozhen HU Xia JIANG Fengchang WU | 2008 | Frontiers of Environmental Science & Engineering2008，2，3： | 2 |

| 8 | Sedimentary characteristics and main controlling factors of the Middle-Upper Permian and Middle-Upper Triassic around Bogda Mountain of Xinjiang,NW China显示文摘Based on field geological survey,interpretation of seismic data and analysis of drilling and logging data,the evolution of geological structures,stratigraphic sedimentary filling sequence and sedimentary system around the Bogda Mountain were analyzed according to the idea of'structure controlling basin,basin controlling facies and facies controlling assemblages'.The tectonic evolution of the basin around the Bogda Mountain can be divided into nine stages.The Middle-Late Permian–Middle-Late Triassic was the development stage of intracontinental rift,foreland basin and inland depression basin when lake,fan delta and braided river delta sedimentary facies developed.Early intracontinental rifting,late Permian tectonic uplift,and middle-late Triassic tectonic subsidence controlled the shape,type,subsidence rate and sedimentary system evolution of the basin.The Bogda Mountain area was the subsidence center and deposition center of the deep water lake basin in the Middle Permian with mainly deep-water deposition and local gravity flow deposition.This area had tectonic inversion in the Late Permian,when the Bogda Mountain uplifted to form a low bulge and a series of fan delta sand bodies.In the Middle-Late Triassic,subsidence occurred in the Bogda low uplift,characterized by extensive development of braided river delta deposits. | YANG Youxing ZHANG Junfeng ZHANG Jinhu GAO Yongjin ZHOU Xingui SUN Xiangcan WEN Lei MIAO Miaoqing | 2022 | Petroleum Exploration and Development2022，49，4： | 2 |
