中文摘要: 利用代表河西地区三条主要内陆河的昌马堡、莺落峡和九条岭三个水文站38年(1959～1996年)逐月径流量资料，分析各年汛期径流量距平百分率，确定径流量丰枯程度；通过对径流量进行正态化处理来确定径流量的干旱指数，并对干旱指数的旱涝等级进行了划分；同时考虑干旱指数的旱涝等级和农业灌溉用水的实际情况，初步对农业灌溉用水提出了一些合理化建议。
中文关键词: 河西地区，内陆河径流量，干旱指数，旱涝等级
Abstract:In terms of 38 Year′s(1959—1996) monthly runoff data of Changmabao,Yingluoxia and Jiutiaoling Hydrological station which represent three main inland rivers in Hexi area respectively,the anomalous percentage of runoff and its degree of high/low flow were analysed.The runoff drought index was specified by processing runoff normally and its grades of dryness/wetness was divided.Considering of the drought index grades and the situation of agriculture irrigating,some reasonable suggestions about irrigating were given.
