| 摘 要： | 在系统归纳总结国内外河道生态环境需水理论研究成果的基础上，结合穿紫河作为一条城市河流的实际情况，应用生态学、环境学和水文学理论，系统分析了穿紫河河道生态环境需水的研究范畴和影响因素，对穿紫河不同时段下的河道生态环境需水进行定量研究。研究得出穿紫河河道生态环境需水平均为2．92m^3／s，城市河道生态环境需水与来水水质和河道沿岸的污染物排放情况关系最为密切。一方面，为穿紫河流域水资源的合理调配提供科学依据，有利于穿紫河生态环境的稳定和良性循环；另一方面，对城市河道生态环境需水理论进行一些探索。

| Abstract: | The ecological and environmental water requirement of Chuanzihe river course in different periods of time quantification- ally was studied based on the theories of ecological and environmental water requirement of river course in domestic and overseas and on the actual situation of Chuanzihe river as an urban river. It was estimated that the average water requirement of Chuanzihe river course is 2.92 m3/s with the maximum value of 4.09 m3/s in Feb and the minimum value of 1.75 m3/s in Aug. |
