Article Preview

Abstract:

This paper analyses the suitable seasonal reduction coefficient and rainwater runoff initial abandon coefficient in Zhangjiakou city, which is selected as a study area and is in upstream of Yongding River. And it analyses the achieve volume of rainwater-resources utilization. Through the analysis on the regional precipitation in study area, it obtained the suitable calculation formulas for the rainwater-storage-pool volume per year in rainwater collecting-reusing system of this area .
