摘要

综合分析了地下水含水层防污性能、 化工企业潜在污染源和地下水价值等关键因素, 以下辽河平原区为研究对象, 构建适宜于该区的地下水环境风险相对风险模型( RRM) . 以地下水水质中化工企业特征污染因子为受体, 识别并量化在区域化工企业分布压力下, 地下水环境系统风险值分布状况. 计算结果显示: 下辽河平原相对高风险区主要分布在沈阳浑河区域, 面积35km2 ; 较高风险区主要分布在沈阳浑河区域外围以及盘锦市辖区, 面积414km2 ; 中等风险区分 布在沈阳、 辽阳、 辽中、 盘锦、 营口市辖区工业集中分布区内, 面积1025km2 , 均需采取针对性的保护措施.

Abstract

Northeast Plain is one of the four Great Plains in China. North east Plain is an important industrial area in both Liaoning Province and the north east region . However, due to rapid economic development in recent years , water pollution and quality deterioration issues have emerged. Assessing ground water environmental risk in the region has therefore become necessary. A new approach to assess environmental risk of regional ground water posed by chemical enterprises is presented . A relative risk model was coupled with risk source analysis, ground water vulnerability index, and receptor analysis. Aspatial analysis tool with in GIS was used to interpolate and annotate data to develop environmental risk maps of regional ground water . Level of risk was divided from high to low level into five ranks( V, I V, I I I , I I , I ) . Areas of relative risk rank (RRR) V was found to cover 35km 2 in the Hun River fan in Shenyang , RRR IV covers 414km 2 around the RRR V area and Panjin city . The model proves a rapid and effective tool to evaluate rationality of regional chemical enterprise layout , to protect ground water and to reduce environmental risk .
