Study On Ecological Environmental Assessment And Recovery Program Design Of Dongjin Mine In Easten Jilin Province

Dongjin mine is located in southern Jilin Province. During its sustaining exploitation,the land subsidence other environmental problems caused by extensive exploitation are moreand more serious. These consequences also bring damage to the ecotope of this study region.In this thesis, a detailed investigation of Dongjin mine was carried out and the basicconditions such as geography, meteorology and hydrology, geology and hydrogeologyanalised, the surface water system, the atmospheric environment system, noise pollution, landutilization are selected to be the four aspects as the environement evaluating index, to give anensurence to the systematic evaluation system. Fuzzy Comprehensive Method, AnalyticHierarchy Process and Empowerment Comprehensive Evaluation method were selected as themethods to appraise the quality status of the environment. And considered about the actualsituation of the study area, the influencing factors of this area are analized comprehensively.Based on the actual situation of Dongjin mine the environmental recovery design and schemeare proposed.
