摘要
矿产勘查活动往往会带来一定的生态环境影响,如何评估这些影响是当前矿产勘查所面临的迫切问题之一。本研究以广东省金矿资源最为集中的粤西金矿带为例,采用生态系统服务价值核算方法,利用单位面积生态环境价值,结合植被恢复时间和矿产资源潜力,量化评估粤西金矿带内的四个主要已知矿区勘查活动生态环境影响,进一步推测量化评估金矿带内其他具有类似成矿地质条件的预测单元勘查活动生态环境影响。评估结果表明:(1)粤西金矿带勘查活动生态环境影响成本较低,相对于其矿产资源潜力带来的社会经济效益而言,微乎其微;(2)广东省粤西金矿带下一步勘查工作方向仍应重点集中在金牛A类预测区、新洲A类预测区与高村A类预测区等资源潜力大、单位资源量生态环境成本低的区域;(3)本研究提出的勘查活动生态环境影响量化评估方法具有易操作、适用性广等特点,可用于其他地理环境下的勘查活动生态环境影响量化评估。
Mineral exploration will inevitably bring some ecological and environmental impacts,and how to quantify such impacts has become increasingly vital.Taking the West Guangdong gold belt with the most concentrated gold resources in Guangdong Province as an example,this study utilized the methods of ecosystem service value accounting,ecological environment value per unit area,vegetation restoration time,and mineral resources potential to evaluate the ecological environmental impact of four major mines caused by exploration in West Guangdong gold belt.Then other metallogenic prognosis provinces with similar metallogenic geological environment in West Guangdong gold belt were further quantitatively evaluated on the basis of the ecological environmental impact of exploration.Results show that:(1)Compared with social and economic benefits of mineral resources potential,the ecological and environmental impact cost of gold mineral exploration is very slight in West Guangdong gold belt.(2)The next exploration in the West Guangdong gold belt should still focus on the Jinniu,Xinzhou,and Gaocun areas,which have large resources and low ecological and environmental costs per unit resource.(3)The proposed quantitative assessment method of ecological environmental impact of exploration activities is easy to operate with wide applicability,which can be utilized for quantitative assessment of ecological environmental impact of exploration activities in other geographical regions.
