摘　　要：为了提升国土污染区域面积测定方法的测定精度,提出GIS遥感技术在国土污染区域面积测定中的应用分析方法。从国土污染形成的主要原因以及结果入手,确定研究区域内国土污染区域面积测定以及评价的主要指标。通过GIS遥感技术提取研究区域内所涉及的指标因子,同时确定评价单元。在上述分析的基础上,选用层次分析方法确定指标权重,对各个测定指标进行无量纲化处理,从而通过GIS遥感技术完成国土污染区域面积测定。仿真实验结果表明,所提方法能够准确测定土污染区域面积。In order to improve the measurement accuracy of the method for measuring the area of land pollution,the application analysis method of GIS remote sensing technology in the area measurement of land area is proposed.Starting from the main causes of the formation of land-based pollution and the results,the main indicators for the determination and evaluation of the area of land-based pollution in the study area are determined.The GIS remote sensing technology is used to extract the index factors involved in the study area,and the evaluation unit is determined at the same time.On the basis of the above analysis,the analytic hierarchy process is used to determine the index weight,and each measurement index is dimensionlessly processed,so that the area of the national pollution area is determined by GIS remote sensing technology.The simulation results show that the proposed method can accurately determine the area of soil pollution.
