喀斯特流域地貌类型对枯水径流特征的影响分析

The analysis of the influence of karst drainage basinson characteristics of the low-flow runoff

从水文地貌流域系统的角度出发,分析喀斯特流域地貌类型与枯水径流的关系,并作枯水流量频率分析计算,按地貌形态组合类型把流域分为喀斯特流域、喀斯特化流域和非喀斯特流域3种类型,初步建立喀斯特流域地貌类型对枯水影响的回归方程并检验,揭示喀斯特地区枯水径流的规律,为分析和预测枯水径流提供理论依据。

Based on the hydrogeology drainage basin system theory,this paper analyses the relations between karst drainage basins and low-flow runoffKarst drainage basins are classified into three types:karst drainage basin,semi-karst drainage basin and non-karst drainage basinA linear equation was preliminarily formed to reveal the regulation of low-flow runoff in karst areasThus,it provides theoretical basis for the prediction and the analysis on the variation of low-flow runoff
