摘要
为提升地区土壤重金属污染评估与风险管控技术,针对铜采选和冶炼等工矿场地带来的土壤重金属污染物,研发鹰潭市土壤重金属环境容量与承载力核算基础数据平台系统.系统采用B/S架构,包括系统安全用户与主界面设置、数据管理与决策支持、基础图层、环境质量评价、环境阈值、静态环境容量、动态环境容量、环境承载力和管理措施建议九大功能模块,新提出了基于环境阈值空间分异的区域土壤环境容量、饱和度以及承载力的概念和精细化算法.系统应用表明,该基础数据平台可为相关部门在区域土壤环境容量与承载力管理方面提供技术支撑.
Abstract
In order to improve the pollution assessment and risk control technology of soil heavy metal in the region,the basic data platform systems called soil heavy metal environmental capacity and carrying capacity of the accounting based on soil heavy metal contaminants from industrial and mining sites such as copper mining and smelting.The system adopts B/S architecture,and has nine modules system including security user and main interface settings,data management and decision support,basic layers,environmental quality assessment,environmental thresholds,static environmental capacity,dynamic environmental capacity,environmental carrying capacity,management measures and recommendations.Newly refined algorithms that regional soil environmental capacity,saturation,and carrying capacity based on spatial differentiation of environmental thresholds were proposed.The application of the system shows that the basic data platform can provide technical support to the relevant departments for the management of regional soil environmental capacity and carrying capacity.
