| Description | Journal: Iop Conference Series: Earth and Environmental Science Wetlands play a significant role in the sustainable development of ecological environment. Nevertheless, the ecosystem of many wetlands has been disturbed and even undermined by recent urbanization and human productive activities. Especially, impact on wetland landscape will affect its ecological function. In this paper, we analyze the changes of wetlands in Southwest China, and have produced the following four results: (1) the area of wetland waters in the study area has been decreasing year by year. From 1990 to 2010 this tendency was particularly prominent; (2) The changes of the international, national and provincial important lake wetlands, which are represented by Lashi Sea, Dianchi Lake and Fuxian Lake, are not obvious in four periods; (3) The sum of the other lake watersheds changed significantly in four periods, slightly higher in 2000 than in 1990, and then decreased rapidly year after year; (4) The changes of the important large reservoirs are more obvious than other lakes; (5) Other reservoir, bottomland and marsh declined sharply by 44.79% from 375.47 km2 in 1990 to 201.07 km2 in 2016;(6) Natural, societal, and economic, as well as human, activities are the major factors of the changes of the wetland landscape in the southwest China.Results suggest that the ecological environment of wetlands should be protected to maximize the function of wetland ecosystems in southwest China. |
