摘要
从遥感数据源的适用性分析出发,探讨了遥感影像水体的自动提取方法、DEM与遥感相结合的完整水库水位-面积关系曲线推求方法以及水库水位-库容关系曲线的建立等.以水丰水库水位-库容曲线复核为例,验证了这些方法的可行性.
By analyzing of the applicability of remote sensing data, the automatic extraction method of water area from the remote sens ing image, the derivation of the complete curve of reservoir water levelarea relationship from DEM combined with remote sensing, and establishment of the curve of reservoir water levelstorage capacity relationship is discussed. Finally, the corresponding example of Shuifeng Reservoir is given to prove the feasibility of these methods.
