为解决地下水数值模拟过程中的空间离散和后处理难题,快速、准确评价地下水资源,在ArcGIS平台上,采用Delaunay三角剖分算法进行空间离散,通过ArcGIS的3D分析模块生成地下水流场图,采用组件对象模型(COM)技术,开发了基于ArcGIS的地下水资源数值模拟评价系统,并应用到滦河平原20%、50%和75%频率年的地下水资源评价.结果表明,迁安市滦河平原区地下水位明显受降水量、河水流量和开采量的控制,其中,滦河径流对地下水位变化影响最大.

In order to resolve the difficulty of spatial discretization and post-processing in the process of groundwater numerical simulation and rapidly and accurately evaluate groundwater resources, Delaunay triangulation subdivision algorithm developed in ArcGIS software was adopted to discretize study area and 3D analysis of ArcGIS was applied to generate and show groundwater flow. Groundwater resources evaluation system developed based on ArcGIS and finite element method was applied to evaluate groundwater resources of 20%, 50% and 75% frequency-year in Luanhe plain area of Qian'an City. The results showed that the groundwater level was controlled by precipitation, water amount of rivers and exploitation amount. The runoff of Luanhe River had the most effects on the groundwater level.
