摘　　要：近年来,土壤重金属污染日益严重,已造成农产品的质量安全问题,并危及人们的身体健康。因此,本文采用GIS技术与地统计学相结合的方法,应用ArcGIS软件对高陵县城镇化进展较快的通远镇农田土壤重金属进行空间分析与污染评价,为该区发展无公害蔬菜基地及国家级安全农产品生产示范区提供了科学的依据,为进一步做好城镇化工作提供有力的保障。In recent years, the worsening of soil heavy metal pollution has resulted in agricultural product quality and safety issues, and endangers people＇s health. Therefore, this paper uses the method of combining GIS technology with statistical analysis and ArcGIS software to analysis the spatial distribution and pollution assessment of heavy metals in Tongyuan that urbanization progress is very quick in Gaoling County, which provide the science basis to develop the non - environmental damage vegetables base and the state - level agricultural product for this area produces the model district. And provide strong guarantee to complete the urbanization.
