Risk Assessment on Environmental Disaster in Nantong City Based on AHP-Topsis Method
摘要
Abstract
Based on the three aspects of vulnerability,exposure and resilience for the environmental risks,an assessment system on environmental disaster was constructed for Nantong City.The regional disparity of environmental disaster risk was analyzed by using a combinative method of Topsis and AHP.Results show that environmental disaster risk varies greatly in the 7 different regions in Nantong city.The spatial risk can be ranged in the increasing sequenced of Haian,Haimen,Tongzou district,Main city of Nantong,Rudong and Qidong,where the minimum risk occurs in Haian while the maximum in Rugao.Potential influence factors are waste air emission,waste water and waste solid,which are caused by the industrialization and the urbanization,as well as the environmental investment are the major reason for the environmental risk.Thus,in order to reduce the environmental risk in Nantong city,the reduction of human activities on the environment and more investment on the environment could be an effective way.关键词
