Resumen
Descripción
As the second largest freshwater lake in China, Dongting Lake has been identified as an important global ecological area, including two National Nature Reserves in the East and West Dongting, and two Provincial Nature Reserves in the South Dongting and Hengling lakes, with a total area of 31,200 hectares. It bears the important function of regulating and storing the water of Yangtze River and the four rivers of Hunan Province, which are Xiang River, Zi River, Ruan River, and Li River. Therefore, it plays an irreplaceable role in maintaining the safety of people along those rivers and ensuring the ecological security in the middle and lower reaches of Yangtze River. Dongting Lake has received intensive attention in recent years. It is listed as the key target in "Green Sword Operation", "Green Shield Operation", and other environmental protection projects at national or provincial level. As an important part of the information management of Dongting Lake, the integrated Information Monitoring System can monitor a variety of natural resources of Dongting Lake in real time, which helps to understand the ecosystem of Dongting Lake in the macro sense, but also dynamically monitor changes in the area and quantity of ecological problems under the influence of human activities, providing detailed information and scientific data for protecting species and ecological environment of the area and making management decisions.
