摘　　要：人类活动对水资源的集约高效利用使绿洲水文循环产生了二元分化,天然、人工水循环的彼此消长,改变了水资源在人工绿洲、天然绿洲及过渡带之间的时空分布和转化条件。以新疆玛纳斯河流域为靶区,根据已有的分布式水文循环模型及水文监测资料统计分析得出,绿洲引用水对2000m以上的山地暂无影响,但平原区水循环发生了了以人工水循环为主导的二元分化。人工绿洲、天然绿洲、过渡带和荒漠间生态统一性出现无序化趋势,造成绿洲-荒漠生态呈现出对抗趋势。The intensive and high - efficient using of water resourse in MANAS River basin has transformed the course of water circle and unity of ecologic service from the circle course and circle peculiarity in arid region. Taking MANAS River basin as target area, according to the distributive hydrologic circle model from senior and hydrologic monitor statistical datum, water resources which was used by oasis didnt affect the mountain area all over 2000km, but it caused the man - made oasis has acquired the two - dimension devision result by man - made water recycle circle of plain area. The ecologic entity between the man - made oasis, natural oasis and transition belt, desert belt has taken on the no - sequence trend. This change has resulted in the confront tendency between oasis- desert ecologic system.
