1981年,在云南全省地下水资源综合评价工作中,采用水文图分割方法来计算地下水天然补给资源。水文图分割法是利用地表水文站资料绘制的水文图求算地下水资源的一种方法。常年性河流的补给。来源于大气降水与地下水。在枯水期间。降水稀少,河水几乎全由地下水供给。而丰水期间,河川径沈的一部分为雨洪水,另一部分为地下水补给。因此结合汇水区内的自然条件,对地表径流观测资料进行分析,是能够把补给河水的地下径流量分割出来的。在地形起伏的基岩山区,地下水运动迅速,以河流为排泄基准面,
In 1981, in the comprehensive evaluation of groundwater resources in Yunnan Province, the hydrological graph segmentation method was used to calculate natural recharge resources of groundwater. Hydrology segmentation is a method of calculating groundwater resources using hydrographs drawn from surface hydrological station data. Perennial river recharge. Sourced from atmospheric precipitation and groundwater. During low water. Precipitation is scarce, and the water is supplied almost exclusively by groundwater. During Fengshui, part of the river’s sink is rain and flood, while the other part is groundwater recharge. Therefore, combining with the natural conditions in the catchment area, the analysis of the surface runoff observation data can segment the underground runoff of the recharge river. In the undulating bedrock mountainous area, the groundwater moves rapidly, takes the river as the drainage datum,
