摘　　要：选取102景Landsat TM影像,通过水体信息分类处理,得到2010年东北地区水库分布图。根据水库分布格局,选取了5个典型区域,进行了1985~2015年东北地区水库数量、面积及其变化研究。结果表明,2010年东北地区共有水库3 722座,总面积为5 327.36 km^2,其中,黑龙江省有920座、吉林省有1 807座、辽宁省有743座、内蒙古自治区有252座水库;1985~2015年期间,5个典型区内的水库数量和面积整体呈增加趋势。The map of Reservoirs in Northeast China was obtained by the water information classification method based on 102 Landsat 5 TM images in 2010. According to the pattern of reservoirs, five typical regions were selected to monitor the dynamic of reservoirs and quantity from 1985 to 2015. The results showed that there were 3 722 reservoirs in Northeast China in 2010, with total area of 5 327.36 km2, including 920 reservoirs in Heilongjiang province, 1 807 reservoirs in Jilin province, 743 reservoirs in Liaoning province and252 reservoirs in Inner Mongolia Autonomous Region. The amount and the total area of reservoirs have been increasing in the selected regions from 1985 to 2015.
