基于RRM模型的化工企业对下辽河平原区域地下水环境风险评价
A risk assessment model of regional groundwater risk due to chemical enterprises in the lower Liaohe River plain
摘要
Abstract
Northeast Plain is one of the four Great Plains in China.Northeast Plain is an important industrial area in both Liaoning Province and the northeast region. However, due to rapid economic development in recent years,water pollution and water quality deterioration issues have emerged.Assessing groundwater environmental risk in the region has therefore become necessary.A new approach to assess environmental risk of regional groundwater posed by chemical enterprises is presented.A relative risk model was coupled with risk source analysis,groundwater vulnerability index,and receptor analysis.A spatial analysis tool within GIS was used to interpolate and annotate data to develop environmental risk maps of regional groundwater.Level of risk was divided from high to low level into five ranks (V,IV,III,II,I). Areas of relative risk rank (RRR)V was found to cover 35 km2 in the Hun River fan in Shenyang,RRR IV covers 414 km2 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 groundwater and to reduce environmental risk.关键词
