Research and application of comprehensive evaluation system of ecological environmental impact of mineral resource development in nature reserves
There are high requirements for the protection of nature reserves.However,mineral resources spa-tially overlap with nature reserves,and a differentiated management policy should be implemented for nature re-serves,so the evaluation of the ecological environmental impact of mineral resource development in nature re-serves is needed at the decision-making level.At present,the evaluation index system of ecological environmen-tal impacts of mineral resource development has been established,and most of the research work focuses on the impacts of mineral development on the environmental geology of mines,and there is little research on the estab-lishment of a comprehensive evaluation index system for the evaluation of ecological environmental impacts of the development of mineral resources in nature reserves.This paper comprehensively analyzes the development characteristics of mineral resources,characteristics of mining enterprises,geological features of mining environ-ment,refers to the technical specifications of mining ecological environmental impact evaluation and ecosystem characteristics of nature reserves,screens out the corresponding index factors,and uses the hierarchical analysis method to provide important references for the determination of the weights of each index.Based on this,a comprehensive evaluation index system for the ecological environmental impact of mineral resource develop-ment and utilization in the nature reserve was constructed.Then,using this system,with 2010 as the base peri-od,through field visits and surveys,data analysis,combined with the evaluation results of remote sensing inter-pretation,the impact of natural mineral drinking water development engineering project on the regional ecologi-cal environment in Guangzhou Maofeng Mountain Forest Park was comprehensively evaluated.The results show that the sum of the weighted scores of each index factor is 84.21 points,and the result belongs to the cate-gory of"suitable for exploitation(development)"in the natural mineral drinking water development engineering project in Guangzhou Maofeng Mountain Forest Park.It verifies the scientificity,applicability,objectivity and operability of the index system.The results of the study have certain reference significance for the evaluation of ecological environment in the same type of mineral water development area.
