河南省临颍县城市水系规划生态需水研究

Study on ecological water demand of urban water system planning in Linying County of Henan Province

生态环境需水量的计算是水系规划计算的关键点,本文采用R2COSS等方法对河南省临颍县水系规划系统的基流量进行了计算,最终计算出规划水系近期新增需水总量1211.01万m^3,远期新增需水总量2529.676万m^3。R2COSS方法计算简单,适用于新建的一些无水文资料的河湖水系系统的生态需水量研究。本文的研究方法也为城市规划水系生态环境需水核算工作起到一定的指导作用。

The calculation of ecological water demand is the key point of water system planning calculation. In this paper, R2COSS method is used to compute the base flow of water planning system in Linying County, Henan province. The result shows that water planning increases in the recent total water demand of 12.1101 million m^3, and 25.29676 million m^3 in the long term. The R2COSS method is simple to compute. It is suitable for studying ecological water demand of the river and lake water system with little hydrological information. The research method of this paper also plays a guiding role in the ecological planning of urban planning water system.
