摘要
河道中的闸坝会改变河流原有的水文情势,进而引起河道及其周边的生态环境状态发生变化。为了掌握闸坝对河流的影响情况,从水质、水量2个方面建立了闸坝对河流水质水量影响的评价指标体系,采用计算评价指标隶属度值的方法,对淮河流域的蚌埠闸、阜阳闸、槐店闸以及蒙城闸进行影响评价。评价结果为阜阳闸的影响程度较大,槐店闸和蒙城闸的影响程度中等,蚌埠闸的影响程度较小。评价结果表明所建立的评价指标体系以及评价方法在实际应用中是可行的。
Dams and water gates may change the original hydrologic regime in river,and ause changes to the river channel and surrounding ecological environment.An index system for evaluating the impact of dams & water gates on water quality and water quantity is established.Then water gates of Bengbu,Wangjiaba,Genglou and Zhoukou in Huaihe river basin are evaluated by calculating grade of membership.The result shows that the impact of water gates on water quality and water quantity of the river as follow: Bengbu water gate's is strong,Wangjiaba water gate's is medium,Genglou water gate's is slight and Zhoukou water gate's is slight.It also demonstrates the feasibility of the evaluating index system and assessment method in practice.
