【摘要】：福建省泰宁县大龙乡饰面用花岗岩矿资源较为丰富,主要集中于双坪村密岭和里崖、东坑村、饶山村。结合泰宁县大龙乡饰面花岗岩石材矿区的实际情况,为促进大龙乡饰面花岗岩石材资源的优化配置和合理开发利用,切实改变资源开发利用中存在的资源浪费和破坏生态环境的现象,本文通过文献法、实地观测法和定点监测法对饰面用花岗岩矿区生态环境影响较大的五个方面进行调查分析,基于AHP法对矿区生态环境质量进行评价,选取植被破坏、环境空气质量、地表水、声环境和水土流失五个矿区生态环境评价因子,采用专家打分法给出评价因子的评分值和判断矩阵,得出各因子的权重,得到矿山生态环境质量综合得分。发现矿山开采引发的主要矿山生态环境问题包括占用土地资源和毁坏大量林地、破坏自然景观及易发地质灾害、破坏乡土植被和加剧水土流失。提出加强退役期生态恢复、加强地质环境保护、强化生态环境管理和减少水土流失等对策。研究结果表明采矿活动引起的主要生态环境问题是植被破坏和水土流失,对空气质量、地表水、和声环境影响较轻；泰宁县大龙花岗岩矿山生态环境质量级别为中等；植被破坏和水土流失对矿山生态环境质量综合得分影响最大。
[Abstract]:Dalong County, Fujian Province is rich in granite ore resources, mainly concentrated in Shuangping Village Miling and Liya, Dongkeng Village, Rao Shan Village. In order to promote the optimal allocation and rational development and utilization of granite stone resources in Dalong Township, and to change the phenomenon of waste of resources and destruction of ecological environment in the exploitation and utilization of resources, this paper adopts the literature method. The field observation method and fixed point monitoring method are used to investigate and analyze the five aspects which have a great impact on the ecological environment of the finishing granite mining area. Based on the AHP method, the ecological environment quality of the mining area is evaluated, and vegetation destruction, ambient air quality and surface water are selected. The evaluation factors of sound environment and soil erosion in five mining areas are given by using the expert scoring method, and the weight of each factor is obtained by using the scoring value and judgment matrix of the evaluation factors. The main mine ecological environment problems caused by mining include occupation of land resources and destruction of a large number of forest land, destruction of natural landscape and vulnerability to geological disasters. Destruction of local vegetation and intensification of soil erosion. It is proposed to strengthen ecological restoration during decommissioning and to strengthen the protection of geological environment. The research results show that the main ecological environmental problems caused by mining activities are vegetation destruction and soil erosion, which have less influence on air quality, surface water and sound environment. The grade of ecological environment quality of Dalong granite mine in Taining County is medium, and vegetation destruction and soil erosion have the greatest influence on the comprehensive score of mine ecological environment quality.
