GIS支持下人类活动对地下水动态影响的定量分析

Quantitative analysis on impacts of human activities on the groundwater resources based on GIS

摘要: 应用地球动力学原理分析和研究了人类活动对水资源变化的影响,提出可将人为作用影响作为一个综合性的抽象指数,通过求取其它因素的变化利用余差法反求得到的计算思路.借助于GIS技术,建立了度量人为作用对地下水动态影响的通用数学模型,并用实例进行了验证,计算结果与实际情况相符,表明所提的方法是可行的.

Abstract: The impacts of human activities can be regarded as an integrated variable,and should be calculated comprehen-sivelg. Based on the theory of geodynamics and GIS,a universal model of the impacts of human activities on the water resources is presented and applied to the western of Jilin province. The results show that the method is practicable.
