摘要

This study focused on the technical measures of revegetation on Molybdenum tailings bank in Huludao, China. Adopting field test method, a revegetation trial was conducted on the Yangjiazhangzi waste molybdenum tailings bank. By composting the urban sludge + rice straw or maize straw inside planting pit to ameliorate tailings matrix, close planting crop to establish line type sand barrier to shelter bush- herbage growth, transplanting nutrition cup bush seedlings and sowing herbage seed on the composting pit to establish root nodule bush-herbage clump, these technical measures can solve the major constraints to plant growth and establish lowcost bush-herbage vegetation. The results show that urban sludge+maize straw composting inside pit is the costeffective measure to improve molybdenum tailings planting matrix; Planting maize sand barrier is a good measure to improve microhabitat. Planting bushherbage clump is a good pattern to resist the extreme Molybdenum tailing environment; Hippophae rhamnoides Linn., Caragana Korshinskii Kom., Medicago sativa Linn, and Astragalus adsurgens Pall, are good pioneer species for revegetation on the molybdenum tailings bank. Experiment proved that the combination of these technical measures can reconstruct vegetation, this vegetation pattern is worthy of reference for similar mine ecological restoration.
