摘要
为进一步掌握韶关市浅层地下污染载荷情况,更科学指导韶关市地下水污染防治工作。本研究基于韶关市地下水污染源调查的基础上,选取单个污染源的污染物毒性(T)、污染源释放的可能性(L)、可能释放污染物的量(Q)作为定量指标,采用评分指数法求出污染源荷载综合指数(PI),并通过ArcGIS软件进行污染载荷计算分析。计算分析结果将韶关市地下水污染源荷载分为5级。研究表明:韶关市地下水污染源以工业污染源、加油站和矿山开采区为主,其中矿山开采区和工业污染源对地下水污染源荷载等级的贡献最大。
In order to further grasp the shallow underground pollution load in Shaoguan,more scientifically guide the groundwater pollution prevention and control work in Shaoguan.Based on the investigation of groundwater pollution sources in Shaoguan,this study selected the pollutant toxicity(T),the possibility of release of pollution sources(L),and the amount of pollutants that may be released(Q)of a single pollution source as quantitative indicators,and the comprehensive index(PI)of pollution source load was obtained by using the scoring index method,and the calculation and analysis of pollution load was carried out by ArcGIS software.According to the calculation and analysis results,the groundwater pollution source load in Shaoguanwas divided into five levels.The study shows that the groundwater pollution sources in Shaoguan are mainly industrial pollution sources,gas stations and mining areas,of which mining areas and industrial pollution sources contribute the most to the load level of groundwater pollution sources.
