Design of Soil Pollution Prevention and Control Evaluation and Analysis Platform based on WebGIS

This study focuses on heavy metal pollution in Yunnan Province and designed and developed a data informatization platform for soil environmental quality monitoring and data informatization for pollution control. The platform integrates a large amount of existing heterogeneous data resources from multiple sources, enabling WebGIS visualization of soil environmental quality and pollution, data analysis and graph presentation, thematic mapping and evaluation analysis report generation, and functions for assessing soil environmental quality and determining the causes of agricultural pollution and building areas [1]. By adopting the latest technological architecture such as NodeJS, VueJS and Cesium, the platform achieves efficient data integration, transmission, analysis and visualization, improving the efficiency of analysis, monitoring and control of soil pollution data. The platform uses the single-factor method, the comprehensive Nemerow index method and the analytical hierarchy process as soil pollution assessment methods, combined with coordinated monitoring of heavy metal content in agricultural products, making the assessment results more comprehensive and accurate. This system will help improve soil environmental quality monitoring and pollution control capabilities in Yunnan Province by providing comprehensive and accurate baseline data and scientific decision support to government agencies.
