摘要
土壤中的重金属是影响土壤环境质量的重要因素,直接或间接危害人类健康。因此,准确评价土壤重金属污染情况,对污染土壤进行有效治理,具有十分重要的意义。本文在传统的土壤重金属污染评价方法的基础上,分析引入地理信息系统(Geographic Information System,GIS)的合理性,结合土壤重金属污染的特点,阐述其在土壤重金属污染评价中的具体应用,并结合GIS的最新技术发展,指出其在土壤重金属污染评价中存在的不足,对GIS在土壤重金属污染评价方面的应用趋势进行展望。
Heavy metals in soil are important factors affecting soil environmental quality,and directly or indirectly harmful to human health.It is of great significance to accurately evaluate the pollution of heavy metals in soil and effectively control the contaminated soil.Based on the traditional evaluation method of heavy metal pollution in soil,this paper analyzed the rationality of introducing geographic information system(GIS)and illustrated the specific application of GIS in the evaluation of heavy metal pollution in soil,such as thematic map making,spatial analysis,early warning model establishment,etc.Finally,the paper pointed out the shortcomings of GIS in the evaluation of soil heavy metal pollution,and the development trend of GIS in the evaluation of soil heavy metal pollution was prospected.
