田纳特法在确定寒区中、小河流生态环境需水量中的修正

Using the modified Tennant method worked on water demand of ecological environment for middle and small river in high and cold area

田纳特法是目前广泛应用的生态环境需水量确定方法之一。在分析我国高寒地区水文气象特征的基础上,运用田纳特方法确定高寒地区中、小河流生态环境需水量。高寒地区中、小河流的流量、水位、流速、河槽特征等水文要素具有自身的特点,在应用中,发现田纳特法的指标不适合当地的实际情况。给出了田纳特法的修正表达式,可用于高寒地区中、小河流生态环境需水量的计算。

Tennant method is one of the method widely used on water demand of ecological environment. On the basis of analyzing hydrometeorology characteristics in high and cold area of our country ,This thesis use the Tennant method worked on water demand of ecological environment for Middle and Small River in high and coid area. the Middle and small river in high and cold area has diffent hydrometeorology characteristics itself in discharge, water level , velocity. In the apply of practices , we find the method was not use for . this thesis set up the modified Tennant method and the formulas . The methods and the formulas of this thesis can be used to determine the water demand of ecological environment for middle and small rivers in high and cold area;
