利用组件式GIS开发平台ArcObjects与可视化开发语言C#,对基于SQL Sever2000和ArcSDE的重金属污染信息系统设计与开发进行研究.以广东省惠州市为例,通过104个观测点,利用C#与Matlab混合编程,用神经网络方法插值出其他未观测点的地理坐标和重金属的含量,并应用单因子评价和地统计分析实现基于GIS空间数据分析和管理的信息系统功能.该系统具有对土壤重金属污染状况进行空间变异分析和评价、数据查询、分析和统计等功能,能实现重金属空间变异的可视化表达,为人们的生产生活以及土壤环境质量研究和决定提供服务.

In this paper the authors have used ArcObjects component based on GIS development Platform and visualization development language C# to study the heavy metal pollution information system based on SQL Sever2000 and ArcSDE.Taking Huizhou City as the research object,based on the data from 104 sampling observation points in the field,the author uses C# and Matlab to program,and works out the the geopraphic coordinates and the contents of heavy metal in other non-obsevation points by the means of BP neural network model and achieve the function of spatial data analysis and information management by single-factor evaluation and geostatistics analysis.This system has the functions of data analysis of heavy metal pollution of soil,data inquiry and statistical research,and it can achieve a cisual expression of spatial variability of heavy metals,and can server for the people＇s production and living,soil environmental quality studies and decision-making.
