甘肃省黄河流域地下水资源评价

ASSESSMENT OF UNDERGROUND WATER RESOURCES OF YELLOW RIVER CATCHMENT IN GANSU

本文根据山丘区多年平均地下水资源总补给量＝总排泄量的水量均衡方程，采用逐日流量过程线（２４年）基流切割法，首次计算出黄河流域各分区地下水资源的补给量和补给模数，并评价了各分区地下水资源的合理开发和利用状况。

Based on the long term equilibrium equation that in mountain area long-period average amount of recharging water should be equal to the amount of discharging water, this paper calculated for the first time recharging amount and its feed module in each region of the Yellow River by using the base ground flow cutting method in which the day to day flow hydrograph (for 24 years) was adapted. Also, reasonable development and present use conditions for underground water in each region were Assessed.
