摘  要:
下辽河平原作为辽宁省最大的冲积平原,是省内最重要的商品粮基地,伴随着农业发展,农业污染也较为严重。水资源问题已经成为该区经济发展的制约因素,因此对下辽河平原地下水污染风险性进行评价,对其社会经济的可持续发展有着重大的意义。综合考虑了含水层本质脆弱性、农业活动和地下水价值三方面因素,重点突出地下水功能价值的重要性,对下辽河平原农业活动对浅层地下水污染风险性进行了综合评价,应用熵权系数法确定各因子的权重,利用GIS软件做出下辽河平原地下水污染风险评价图,为下辽河平原地下水资源保护及管理提供依据。

摘  要:
The Lower Liaohe River Plain is the biggest alluvial plain and the most important commodity grain base in Liaoning Province.With the development of agriculture,the problem of agricultural pollution has become more and more important.Problems of water resource have become the restricting factors of the development of the regional economy.So study on the Lower Liaohe River Plain's groundwater contamination risk assessment is very important for the sustainable socio-economic development.For groundwater contamination risk assessment,three factors,including aquifer vulnerability,agricultural activities and groundwater value,are taken into account,and the importance of groundwater value is stressed.The weight of each factor is determined by entropy weight coefficient method.Then the maps of the Lower Liaohe River Plain groundwater contamination assessment are made by using GIS software,which can provide the basis for the protection of groundwater resources and management.
