工业园区土壤重金属时空分布信息查询分析系统

Soil heavy metal spatial and temporal distribution of industrial park information query and analysis system

工业园区及周围土壤中的重金属富集程度较高,容易发生重金属污染事件。以宝鸡市长青工业园区为试点,通过3年分批次的土壤布点、采样和分析,建立了工业园区土壤重金属时空分布信息查询分析系统。该系统基于WebGIS,采用B/S架构、MySQL数据库及PHP5.0+JavaScript语言,开发了GIS空间分析与环境监测数据管理的集成框架软件。系统集成了空间地理信息、污染源信息及各监测专题信息,并实现了污染源信息、监测点信息的增删改查及土壤中重金属浓度的多维度查询统计、土壤中重金属环境限制预警、工业园区及周围土壤环境质量评价等多项功能。该系统为决策管理提供一个数据平台,对安全利用国土资源、保障工业园区工作人员及周边居民环境安全有重要意义。

Heavy metal pollution incidents tend to occur in industrial parks and surrounding areas because of their high enrichment of heavy metals. In this study,the Baoji Changqing Industrial Park is taken as a pilot project and an information query and analysis system is established for distributing,sampling and analyzing the spatial and temporal distribution of heavy metal in soil for three years. The system is based on WebGIS,B /S structure,MySQL database and PHP5. 0 + JavaScript and a framework that integrates the GIS space analysis and environmental monitoring data management is developed. Geographical information,pollution source information and monitoring information are integrated in the system,which are allowed to add,delete,modify and query.Moreover,the system can also perform functions,such as the multidimensional query of heavy metal concentrations,the restriction warning of heavy metals in soil,the assessment of soil environmental quality for industrial parks and surrounding areas,etc.. It provides a data platform for decision-making management,which is significantly useful in terms of the use of land resources and the environmental safety of residents in industrial parks and surrounding areas.
