水资源系统中地下水系统数学模型研究

Research of Mathematic Model forGroundwater of Water Resource System

地下水系统作为水资源系统的一个有机组成部分，与地表水、土壤水、大气水之间有着极其密切的联系。从水资源系统出发，研究地下水与地表水、土壤水、大气水之间的内在转化关系，并将此种联系定量化耦合进地下水系统模拟模型，从而建立统一于水资源系统的地下水系统数学模型。这是构建大气、植物、包气带地下水系统（ＧＳＰＡＣ）统一体的重要组成部分。研究表明，所建模型对于准确预测地下水动态变化、提高地下水资源评价的精度和促进地下水、地表水、土壤水和大气水之间转化的研究有着重要意义。

As a part of water resources system, groundwater is closely related to surface water, soil moisture and precipitation. This paper analyses in detail the inherent relations between groundwater and surface water, soil moisture, precipitation, then embedded the relation into groundwater system simulational model to get a more rational groundwater system mathematic model. The study shows that with the newbuilt model, groundwater resources can be evaluated and groundwater regince can be forecast more accurately. At th same time, the model will play an important role in GSPAC studying.
