摘要
基于GIS和遥感技术对不同时期的遥感影像数据进行处理,获取安庆沿江8个主要湖泊5个时期的水域面积,分析其时空变化特征,结合相关资料与实地考察,总结了引起水域面积变化的原因,并对合理利用与保护湖泊水资源的对策进行了探讨。
Different periods of remote sensing image data were processed on the basis of GIS and remote sensing technology and, as a result, data concerning five periods of water areas of eight main lakes along the Yangtze River were obtained. Based on an analysis of their temporal - spatial variation characteristics in combination with related data and field investigation, this paper has summed up the causes for the change of water areas and dealt with the countermeasures for rational utilization and protection of lake water resources.
