摘　　要：湿周法是河流生态环境需水量的确定方法之一。文章针对其应用中对多组实测数据确定临界点困难的实际情况,对该法进行了改进。提出了湿周法确定临界点理论公式,并利用实测数据对选定的西南岔河流域的三个河段进行生态环境需水量计算。The wetted perimeter method is one of the methods to determine the river eco-environment water demand.According to the practical difficulty of determining the critical point from multi-group measured data,the paper improves the wetted perimeter method,proposes the theoretical formula to determine the critical point by using this method,and calculates the eco-environment water demand for the three rivers of selected Xi' nancha river basin through the measured data.
