Assessment on ecological environment impact caused by the exploitation of a uranium mine

On the basis of investigation, the assessment index of ecological environment impact is determined from the aspects of natural eco-environment and social eco-environment. Both qualitative analysis and quantitative assessment are adopted for assessing the ecological environment impact during the exploitation of a uranium mine in Jiangxi province. The results show that some values of the assessment index in natural eco-subsystem decline slightly, while those of the assessment index in social eco-subsystem ascend so that the ecological environment quality around the uranium mine ascend slightly. Moreover, some reasonable advices on eco-environment protection measures are put forward in order to build a ecotype uranium mine. (authors)
