摘　　要：贵州省岩溶比较发育,西北部地区,海拔较高,水资源条件相对较差。跨流域引水、调水工程比较常见。小流域实测水文资料比较缺乏,引水量分析计算相对比较困难。本文以解决六盘水市梅花山旅游景区供水问题为例,根据余家寨小河向梁家沟水库引水布置方案,采用气象站逐日降水资料,结合设计暴雨、设计洪水过程,按照水量平衡原理,计算分析得出余家寨小河多年平均引水量。In Guizhou province,karst is relatively developed;the northwest region has higher altitude and fairly poor water resources.Inter-basin water diversion or transfer projects are frequently seen.For small watershed,the mea⁃sured hydrological data are scarce,and it is relatively difficult to analyze and calculate the water diversion volume.In order to solve the water supply problem of Meihua Mountain scenery area in Liupanshui City,water diversion from Yujiazhai River to Liangjiagou reservoir was arranged.Based on the daily precipitation data of meteorological station,combined with design rainstorm and design flood process,according to the principle of water balance,the average annual water diversion of Yujiazhai River was calculated and analyzed.
