Environmental analysis and assessment of ecological restoration of an abandoned gold mine in Tieli City,Heilongjiang Province
摘要
Abstract
Environmental analysis and assessment of ecological restoration in mining areas are of great significance for achieving ecological balance and promoting sustainable development in mining regions.Taking an abandoned gold mine in Tieli City as the study area,this paper investigates the constraints affecting the effectiveness of ecological restoration through field surveys of plant community characteristics and soil stratification,as well as chemical analyses of collected soil and plant community samples.Based on soil stratification and current vegetation community characteristics,the entire mining area was divided into seven ecological subzones,i.e.meadow soil-type primary forest area,meadow soil-type natural restoration area,waste rock backfill area,artificial planting restoration area,natural restoration area,primary forest area,and tailings ecological restoration area.Using the primary forest area as a reference,the changes in major soil nutrient factors before and after mining were compared.The results showed that soil pH changed from acidic to alkaline.Except for the tailings ecological restoration area,the major soil nutrient factors decreased significantly,with the greatest losses observed in organic matter and total nitrogen.From the perspective of soil heavy metal contents in each ecological subzone,the abandoned gold mine cannot be developed as agricultural land at present.Among the subzones,the waste rock backfill area exhibits severe arsenic contamination,and urgent pollution remediation therefore treatment is required.关键词
