摘　　要：水体作为国土资源的关键要素,其水体面积变化在水资源调查、变化检测及大型水利设施建设评估等方面具有非常重要的意义。由于区域山体阴影、建筑等因素的干扰影响,带来域内所有湖库水体进行一次性提取的难点,文中以landsat8为数据源,研究提出一种MNDWI+水体追踪识别的方法;并以京津冀区域为例,应用本方法在该区域湖库水体的提取精度达到97.5%以内,与常规方法相比,实现了大区域湖库水体的一次性快速精确提取。As a key element of land resources,the change of surface water area is important for survey of water resources,time series change detection on water usage,assessment of large-scale water conservancy facilities,and so on.In this paper,Landsat 8 is used as the data source,because of the interference of regional mountain shadow,building and other factors,which brings the difficulty of extracting all lakes and reservoirs water bodies in the region at one time.A method of MNDWI+water body tracking and recognition is proposed.Beijing-Tianjin-Hebei as an example,the extraction accuracy of this method in lakes and reservoirs water bodies in the region is within 97.5%.Compared with the conventional method,one-time rapid and accurate extraction of lake and reservoir water bodies is achieved.
