| Abstract:In view of the increasingly serious problem of soil pollution,it is necessary to develop a rapid and efficient method for analyzing the pollution situation and forecasting future pollution, and GIS is just a good means to solve this problem. According to the method and principle of ArcView GIS produced by ESRI Company, the authors designed and developed the Beijing Soil Pollution Early Warning System based on geochemical data and heavy metal data. This paper describes the function and structure of the system, and discusses the construction of the database, the designing of GUI (Graphic User Interface) and the combination with other application softwares. This system provides such functions as data management and query, spatial analysis, forecast and mapping. Its GUI is friendly and is easy to use and maintain. The construction of this system will provide effective information support for pollution prevention of Beijing and improve soil pollution management and decision-making. As Beijing is a typical area, the successful development and application of Beijing Soil Pollution Early Warning System will serve as a good example of soil pollution prevention and control for other areas of China. |
