地下水均衡特性曲线是定性和定量地描述地下水,尤其是浅层地下水均衡特性的曲线,它将水文、气象、植物等各种影响地下水动态因素综合起来,利用观测到的地表下不同深度的蒸发和入渗数据得到一条简单曲线,根据谈曲线,可以定量计算出不同深度地下水补给和排出量,根据区域曲线平衡点的位置,按照不同地点水位位置,划分出浅层地下水的补给区和排泄区,进而,定量地计算出区域地下水的补给量和排泄量,根据平衡点位置土区域水位埋深,尚可划分出和壤盐渍化带,对土壤和浅层地下水污染研究具有重要意义。本文主要以该理论的基本原理出发,讨论地下水均衡性曲线构成,以及在水文地质中的应用。
The groundwater equilibrium characteristic curve is a curve that qualitatively and quantitatively describes the equilibrium characteristics of groundwater, especially the shallow groundwater. It integrates various hydrological, meteorological and plant dynamic factors that affect the groundwater. Based on the observed evaporation at different depths under the subsurface Infiltration data obtained a simple curve, according to the curve, we can quantitatively calculate the depth of groundwater recharge and discharge, according to the location of the regional curve equilibrium point, according to the location of the water level at different locations, the division of shallow groundwater recharge area and drainage area, Furthermore, the recharge and discharge of groundwater are quantitatively calculated. According to the depth of groundwater level at the equilibrium point, it is still possible to classify the soil salinization zone, which is of great significance to the study of soil and shallow groundwater pollution. In this paper, the basic principle of the theory, starting to discuss the composition of groundwater equilibrium curve, as well as in the application of hydrogeology.
