以河北省雄县水资源平衡调控研究区为例 ,对水平衡分析方法及适应性进行了评价 ,在分析研究区水文地质条件和水循环要素的基础上 ,选择相关分析法进行了研究区水平衡计算 ,建立了地表水 (降雨和地面引水 )和地下水位变幅的相关关系 ,以及地下水储量和地下水位的相关关系 ,并对两种相关分析计算和结果进行了分析和对比 ,从中得到研究区地下水多年平均持续平衡的需水量 ,即农业用水量值
Taking Xiongxian County, Hebei Province as an example, this paper evaluates the methods and the adaptability of water balance analysis. Based on the analysis of the hydrogeological conditions and water cycle elements in the study area, the correlation analysis is used to analyze the water balance in the study area The correlations between surface water (precipitation and groundwater diversion) and groundwater level fluctuation and the correlation between groundwater storage and groundwater table are established. Two related analysis and calculation and results are analyzed and compared, and the study area The average continuous groundwater demand for many years, that is, the value of agricultural water use
