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

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。

The impacts of human activities can be regarded as an integrated variable, and should be calculated comprehensivelg 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
