| Abstract: | 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. |
