Abstract:
Taking Taerqi iron mine′s tailings reservoir in the original forest area at the junction of Ewenki Autonomous banner and Yakeshi city as the research object,soil mechanical composition,pH,conductivity and soil nutrients (alkaline-hydrolysis N,available P,available K,organic matter) around the tailings reservoir were measured,and the correlation between each indexes were analyzed,the effects of tailings reservoir on physical and chemical properties of surrounding soil in forest area iron mine was studied,in order to provide reference for land reclamation and ecological protection in this area.The results showed that tailings reservoir had a great influence on physical and chemical properties in 0-20 cm soil layers around the tailings reservoir.Sample areas sorted from CK,B,C,W to S,the soil coarse particle matter were decreased,the fine particle matter were increased,the soil pH was increased gradually,the conductivity and soil nutrient content were decreased rapidly,and there were significant differences in sample plots (P<0.05).Correlation analysis indicated that soil nutrients had significantly correlated to each other,the changes in soil nutrients due to the changes in sand gravel,fine silt,pH and conductivity,they were important factors to affect soil fertility.
