摘要
通过生物措施、工程措施和耕作措施对滇中地区典型小流域——王家箐进行综合治理,对治理前后气象、水文资料进行观测分析。得出如下结论(1)采取水保措施不改变流域地下水的退却过程。(2)该流域产流模式是超渗—蓄满兼容的转换产流模式,治理前以超渗为主,治理后以蓄满为主,且有逐步向蓄满产流转变的趋势。(3)采取水保治理综合措施后,径流中地下径流含量增加,流域地下蓄水量也相应增加。
In order to control soll and water loss in Wangjiaqing watershed in the central Yunnan Province, engineering, biological and crop cultivation measures were implemented. The data of climate,hydrology were collected and analyzed. It is concluded that after conservation implementation the reducing procedure coefficient of ground water is constant ,the model of runoff yield includes excess infiltration and excess storage of ground runoff and water is significant rising. at the same time,and excess storage is the main pattern ,the amount
