| 摘 要： | 西北地区生态环境对水的变化十分敏感，跨流域调水成为影响生态环境的关键因素．大通河跨流域规划调水工程较多，将引起水文情势的剧烈变化，对河道内生态和水环境影响产生显著的效应，基于生态需水、河流纳污能力等理论，分析研究了调水前后可能引起的河道生态环境各要素变化的程度和范围．结果表明，调水引起的水文情势变化，对河道内水生生态、水环境和河谷陆地生态的影响十分显著．

| Abstract: | Ecological Environment is quite sensitive to Water Resurce changes initiated from inland river basins in Northwest China,Outputing water is become a key effective fator to influence ecological environment.Have many water transfer Enginering to outup water in plan of Datong river,which will bring severe changs on water resources,make an influence of extent of eccology in riverway and water entironment factor.Based on eco-hydrology and theory of river's absorb waste water power,this articl,analysed posible chang's extent and scope of variors factors elating to ccology and water entironment,when Outputed water,Researched the result state:State of affairs on hydrographic changes,effect are mach markedness to ecology in riverway and water entironment. |
