Taining Dalong Granite Mine Ecological Environment Investigation And Countermeasures Research

Dalong township in Taining county of Fujian province finishes with granite are rich mineral resources, mainly focused on the Miling and Liya of Shuangping village, Dongkeng village, Raoshan village. Combined with the actual situation of Taining Dalong township facing granite mining area,to promote the Dalong township optimal allocation and rational development and effective utilization of facing granite stone resources, changing the phenomenon of waste and damage of ecological environment of the resources development and utilization of resources, this article through the literature method, field observation method etc. facing with granite mining area ecological environment influence five aspects were investigated, based on the AHP method to evaluate the mining area ecological environment quality, selection of vegetation destruction, environmental air quality, surface water, sound environment and soil and water loss five mining area ecological environment evaluation factors, using expert scoring method evaluation factor score values and judgment matrix is given, concluded the weight of each factor, the mine ecological environment quality comprehensive score. Founding that the main mine ecological environment problems caused by mining including occupation of land resources and destroyed a large number of forest land, destruction of natural landscape and prone to geological disasters, destruction of native vegetation and soil and water loss. Put forward to strengthen the cutover ecological restoration, and strengthening the protection of geological environment, strengthening the management of the ecological environment and reduce the water loss and soil erosion and other countermeasures. Research results show that the main ecological environment problems caused by mining activities is the destruction of the vegetation and soil and water loss, the impact on air quality, surface water, harmony environment lighter; Taining Dalong granite mine ecological environment quality level is medium; The destruction of the vegetation and soil erosion had the greatest influence on mine ecological environment quality comprehensive score.
