Study on Soil Remediation by Four Greening Tree Species in Coal Mine Reclaimed Area

摘要

The effects on soil remediation were compared and analyzed by field sampling and laboratory monitoring after the implementation of landscape engineering in Panyi coal mine reclaimed area. It was indicated that the damaged mine ecological environment had been improved and recovered to a certain extent and the physical and chemical properties and fertility levels of the soil had been significantly improved. The concentration of Cu, Cr, Mn, Ni, Hg and as in the soils had reduced efficiently. Through the analysis of the root zone soils , which were been collected from Populus, Ligustrum lucidum Ait, Cedrus deodara and Sabina komarovii (Florin)Cheng et W.T.Wang. Populus and Ligustrum lucidum Ait were screened out as dominant tree species in coal mine reclamation district. This study might offer scientific foundation for ecological restoration in coal mine and selection of different afforestation species.
