为研究如何在生态环境需水基础上进行合理的水资源配置，对宁夏固原城乡安全饮水水源工程受水区河道内生态环境需水量进行了分类和界定，并对河道内每一类生态环境需水量进行计算分析，结果表明：受水区各县（区）的河道内生态环境需水量由大到小依次为原州区、彭阳县、海原县、西吉县，基本呈南部山区向中部干旱带递减的趋势；受水区河道内基本生态环境需水量占河道内生态环境需水量比例较大，均在80％左右；受水区河道处于较好状况时的生态环境需水量占径流量的33％～35％。
為研究如何在生態環境需水基礎上進行閤理的水資源配置，對寧夏固原城鄉安全飲水水源工程受水區河道內生態環境需水量進行瞭分類和界定，併對河道內每一類生態環境需水量進行計算分析，結果錶明：受水區各縣（區）的河道內生態環境需水量由大到小依次為原州區、彭暘縣、海原縣、西吉縣，基本呈南部山區嚮中部榦旱帶遞減的趨勢；受水區河道內基本生態環境需水量佔河道內生態環境需水量比例較大，均在80％左右；受水區河道處于較好狀況時的生態環境需水量佔徑流量的33％～35％。

In order to study how to allocate water resources reasonably based on eco-environmental water demand,this paper classified and defined the eco-environmental water demand of reception river channels of urban and rural safe drinking water source engineering in Guyuan area of Ningx-ia,and calculated each kind of eco-environmental water demand of river reaches. The results show that the quantity of eco-environment water de-mand from high to low is Yuanzhou District,Pengyang County,Haiyuan County and Xiji County,which basically presents decreasing trend from the southern maintain area to the central arid zone;the basic eco-environmental water demand has larger proportion of the total eco-environment water demand of river reaches and all of the percentage is about 80%;when the river reaches are in good conditions,the eco-environmental water demand is 33% -35% of runoff. The results can provide references for reasonable development,utilization and allocation of water resources in the recep-tion area.
