摘要
鄱阳湖湿地对长江洪水调蓄、候鸟保护等具有重要意义。在两景Land-Sat影像解译的基础上,选择典型区域,在GIS支持下对湿地土地利用/覆盖变化进行分析,同时对湿地生态资源利用和环境保护的相关问题进行了探讨。结果表明,人类活动是湿地土地利用/覆盖变化的重要驱动力。
The wetland of Poyang Lake is an internationally important wetland that can regulate and store the flood of the Yangtze River and protect the migratory birds etc. Based on the interpretly of landsat images, this paper choses the typical area and analyzes the land use and land cover change of the wetland on the basis of GIS technology, discusses the wetland ecological utilization of resources and relevant problems of environmental protection are discussed. The result shows that the human activity is the important driving force of the change.
