岩溶山区地表水资源的计算方法

通过分析滏阳河岩溶山区的产流特征,探讨了该区地表水资源的计算方法,提出了在进行水资源评价时,首先依据水文地质资料,划定岩溶山区地下集水区范围,在该范围内再划分各河的地表集水区;进而分别计算出地下集水区的河川基流量及区内各河流的地表径流量,两者相加,便得到岩溶山区的地表水资源量。

Calculating Method of Surface Water Resources of Karst Mountainous Area

The calculating method of the surface water resources of Fuyang River karst mountainous area is to be explored in the paper through analyzing its runoff yield characters.In the course of water resources assessment,the scope of the underground catchment basin should be firstly delimited and the surface catchment area of each river is to be divided based on the hydrogeological materials in this scope.The base discharge of the underground catchment basin and the total surface run-off of every river can be worked out respectively.Then the total amount of the two kinds of discharge is the amount of surface water resources of this area.
