| 中文摘要 |
| 地下水污染源的有效识别与分级对地下水污染风险源识别和地下水污染防控区划具有重要意义.本研究通过对北京市平原区主要污染源进行解析,构建了以特征污染物属性与污染物排放量计算污染源危害性的量化计算方法.运用ARCGIS 9.3软件实现了北京市平原区的污染负荷空间分布和污染物属性的叠加分析,得到地下水污染源识别与危害性分级.结果表明,该方法能够较为细致准确地反映出污染源的危害性分级,识别结果表明工业污染源对北京平原区地下水污染贡献最大,其次是城镇居民区和垃圾场. |
| 英文摘要 |
| Effective identification of groundwater pollution resources and grading has a significance on the identification of groundwater pollution risk, prevention and control. In this research, through groundwater pollution sources analyzing, a quantitative calculation method of the pollution sources hazard based on representative contaminant properties and pollutant emission amount was built. The ARCGIS 9.3 software was used to perform the distribution characteristics of the pollution loads and contaminants properties overlaying analysis in Beijing plain, then the identification and grading of pollution resources were achieved. The research results showed that this method could reflect the grading of pollution resources meticulously and accurately. Identification result shows that the industrial zones are the most seriously polluted areas, followed by the urban residential areas and landfill sites. |
