广东省典型露天开采矿山地质环境遥感监测和矿山生态环境评价
Geological environment monitoring and mine ecological environment evaluation of typical open-pit mining based on remote sensing in Guangdong province
摘要
Abstract
[Objective]The long-term,high-intensity mining activities in Guangdong Province have generated economic benefits while also damaging the ecological environment of mining areas.There is an urgent need to conduct remote sensing monitoring of development activities in typical open-pit mines.[Methods]This study,based on remote sensing technology,utilized Gaofen-2(GF-2)and Landsat 8 data to extract geological environmental information of the mining area in the study region.The latest development status and ecological environment conditions were obtained.[Results](1)Monitoring based on GF-2 remote sensing data revealed that,as of the end of 2023,the total area occupied by mining activities in the study region was 187.17 hm2.The area of different land use types associated with mining activities,ranked from largest to smallest,includes solid waste,mining infrastructure,excavation sites,restoration/treatment areas,and transfer sites.All excavation sites are located within mining concession boundaries,indicating compliance with authorized limits.(2)Ecological environment assessment was conducted by calculating the Remote Sensing Ecological Index(RSEI)for the study area using Landsat 8 data.The results show that the overall ecological environment in the study area is relatively good,with"excellent"being the predominant grade,mostly located in vegetated regions.Areas rated as"poor"and"very poor"are relatively limited and primarily concentrated in urban areas,major transportation corridors,and areas of mining activity.(3)From 2020 to 2023,the ecological environment quality in the study area gradually deteriorated.The area classified as"excellent"and"good"decreased progressively,while the area classified as"fair,""poor,"and"very poor"gradually increased.[Conclusions]The ecological environment in areas affected by mining activities has undergone significant changes.Mining activities have exerted a clearly negative impact on the ecological environment quality in the region.The findings of this study can provide a basis for effectively curbing the disorderly development and waste of land resources,thereby promoting the harmonious coexistence of mining development and ecological environmental protection.关键词
