| 摘 要： | 面对日益严重的土壤重金属污染问题,必须采用快速高效的方法对污染趋势做出预测预警。本研究建立了土壤重金属污染预警模型和土壤重金属污染超标年限预测模型,并在GIS技术支持下,开发了基于ArcView GIS的预警预测程序模块,实现了对土壤重金属污染的预警预测。最后以北京市及其近郊区为实例,对该区重金属污染进行了预警并对Pb元素超标年限进行了预测,取得了较好的预警预测结果。

| Abstract: | Betimes and high efficiency method must be used to forecast pollution trend in the face of more and more serious problems of soil heavy metal pollutions.In this research,the soil heavy metal pollution forecast model and soil pollution heavy metal element overtake standard early warning model was established and forecast extension was developed based ArcView GIS support by GIS technique,and then realized forecast and early warning for soil heavy metal pollution.Lastly,taking Beijing City include its suburb as instances,warning its heavy metal pollution and forecast Pb element overtake standard fixed number of year and a good forecast result was gained. |

| Keywords: | heavy metal pollution GIS early warning overtake standard year forecast |
