基于GIS的土壤重金属污染分析与模拟系统设计

Design of Soil Heavy Metal Pollution Analysis and Simulation System Based on GIS

作为环境质量评估的重要指标之一,土壤重金属污染程度对环境质量具有重要影响。为了了解土壤重金属污染现状以及评价重金属污染对环境的影响,利用GIS平台、MySQL数据库、空间分析方法、土壤重金属污染扩散模型等关键技术和方法,设计并开发了基于GIS的土壤重金属污染分析与模拟系统。系统实现了重金属污染分析、二维扩散模拟等功能,可为大面积土壤重金属污染的预防与治理提供技术支持。

As one of the important indicators of environmental quality assessment,the degree of heavy metal pollution in the soil has an important impact on environmental quality.In order to understand the status of soil heavy metal pollution,and evaluate the impact of heavy metal pollution on the environment,we used GIS platform,My SQL database,spatial analysis method and soil heavy metal pollution diffusion model to design and develop a soil heavy metal pollution analysis and simulation system based on GIS.The system can realize the functions of heavy metal pollution analysis and two-dimensional diffusion simulation,which can provide technical support for the prevention and treatment of heavy metal pollution in large areas of soil.
