Study on Vegetation Restoration in Gold Mining Wasteland inDaxing`an Mountains of Heilongjiang Province
摘要
Abstract
The vegetation restoration of gold mining wastelandwere studied in the Daxing'an mountains.The characteristics of structure community and the difference of species diversity in different vegetation restoration stages was investigated.The relationship between restoration of vegetation and soil nutrient were analyzed.The results showed that recovery status of vegetation presented three layer structure:the krummholz forest,the mountain cold warm thin forests and mountain boreal forest.Vegetation restoration patternwas secondary bare land vegetation restoration pattern of arbor+shrub+herb.The arbor species were Larix gmelini(Rupr.)Rupr.,Pinus sylvestris var.mongolica Litv.,and Betula ermanii Cham.The shrub species were Hippophae rhamnoides L.herbaceous with Cleistogenes hancei,Medicago sativa L.,Aster tataricus L.,Trifolium repens L.and Belamcanda chinensis (L.)of the highest survival rate.It indicated that the species diversity increased with the increase of vegetation restoration time,and species diversity index was significantly positive correlated with soil organic carbon,total nitrogen,total phosphorus and available potassium.Because the vegetation recovery is a long process and the quality of formed vegetation was the poor,artificial seeding is the necessary measures for ecological restoration关键词
