| 摘 要： | 1IntroductionWith the improvement of people's living standard and economic development, the demands for high quality water resources have been growing, meanwhile, water pollution has become increasingly. According to the survey, most of the rivers, lakes and reservoirs are threatened by the pollution and eutrophication. To solve the problems, and to control the deterioration of water environment of lakes of Dongting, Boyang, Qinghai, and to find the best reclamation measures, experts on lake…

| Abstract: | The environment evolution of Wuliangsuhai wetland since 1986 is analyzed based on the remote sensing principle. The total water area of Wuliangsuhai lake has been increased during the past 17 years. The open water area had an increasing trend before 1987, and the trend was decreasing up to 1996, then the trend has increased again since 2000; the variation of the water area with dense aquatic weed is basically contradictory to the variation of open water area. The natural reed area had been decreased before 1987, and then it has been increased. The areas of shallow water and swamp have been slightly increased, in fact, the variations are quite steady. The artificial reed area has been increased since the reed plantation was started in 1988. The relationships of the water environment, the climate, hydrology and different types of areas are discussed, and then the technological measures for sustainable development and utilization of Wuliangsuhai lake water environment are proposed. |
