中文摘要：

目的探讨银川平原水资源开发与绿洲稳定性之间的内在联系。方法应用自然地理方法分析银川平原水文条件、水资源赋存及黄河水资源利用状况。从绿洲水热平衡指标、黄河水量的波动性和递减趋势、银川平原荒漠化和水环境污染等层面分析银川平原绿洲的稳定性。结果银川平原人工灌排渠沟系统已成为地表水系的重要组成部分，地下水与地表水转化关系密切，形成黄河水-渠系（灌溉）水-潜水的整体循环系统。水热平衡分析结果表明，银川平原绿洲生态系统呈退化趋势，在黄河来水量波动大和递减趋势下，不宜大面积扩大引黄灌溉面积，应重视银川平原地域系统生态的整体平衡，注重与周边各大地域系统的关联耦合作用，并有效治理工业废水、城镇污水对水环境的污染。结论在多种不利因素的耦合作用下，银川平原生态环境有进一步恶化的趋势，形成生态环境易受损机理。银川平原绿洲的稳定性取决于该地域系统的人类活动与水环境的整体平衡。

英文摘要：

Aim To discuss the immanent relation between the water exploitation of Yinchuan plain and the oasis＇ stability was discussed in the article. Methods Amalyze hydrological condition, water resource storage and using, and the exploitation of artificial oasis of Yinchuan plain ,as well as the stability of Yinchuan plain＇s oasis from some lays such as the index of oasis＇ water and heat balance, the fluctuation and digression trend of the Yellow river, the desertation of Yinchuan plain and the pollution of water environment. Results The artificial irrigation and drainage trench system of Yinchuan plain had become the important element of surface water, the affinity indwells between the ground water and surface water, then the unitary circulation system which covers the Yellow river＇s water-trench （irrigation） water-shallow water comes into being. There should be a dynamic balanceable lay among the Yinchuan plain＇s ecological system and the leading water quantity from Yellow river and the ground water resource. Conclusion Under the coupling effect of multi-adverse factor, the farther exasperate trend is embodied in Yinchuan plain＇ s eco-environment, and the easily injured mechanism is formed. The stability of Yinchuan plain＇s oasis lie on the unitary balance between the water environment and human activity of this region system.
