摘　　要：为了监测福州八一水库枯水期水域面积变化状况,从Google Earth数据库下载2013—2015年共3期冬季(1—2月)的高分辨率卫星影像,通过目视解译方法提取水域边界。研究表明,水域面积逐年减小,其中2013年面积最大达23.54hm^2,接近最大库容面积,2015年面积最小,只有7.89hm^2;水域面积与降水显著相关,相关系数超过0.983。In order to monitor water area of Bayi Reservoir in Fuzhou in low water seasons,three phase high-resolution-satellite images in winter （from January to February） were downloaded from Google Earth database Server,and extracted the water border by visual interpretation of remote sensing images.Research shows that the water area was reduced year by year.It is 23.54 hm^2 at 2013,closing to the maximum water area of reservoir;the water area is the smallest,being 7.89 hm^2.It is significant correlation between water area and rainfall and the related coefficient exceed 0.983.
