Study On The Vegetation Restoration Effect Of Coal Gangue Waste

Gangue is currently China’s largest solid waste, not only Zhanya cultivated land, butalso seriously affected the ecological environment around the. Vegetation restoration ofabandoned coal mine land reclamation is an effective method to ecological environment. Oncoal gangue vegetation reclamation ecological and soil effect evaluation, not only isadvantageous to measure the local ecological recovery status, but also for the follow-up ofvegetation reclamation has great reference. This article through to the Shanxi ChangzhiChangcun coal gangue waste land, vegetation reclamation in10years after the ecologicalbenefit evaluation of research, explores the vegetation and reclamation of small local climate,soil physical and chemical characteristics influence. The main conclusions are as follows:(1) Gangue Mountain Vegetation Reclamation can effectively improve themicroclimate around coal gangue; small climate in the air temperature and relative humidityhas a significant positive correlation; reasonable planting density can play a better role in thereduction of the wind.(2) gangue vegetation reclamation on soil physical properties have a significantimpact, locust can better improve the soil bulk density and water content; torch forest canbetter improve the soil capillary porosity and bulk density of soil.(3) Gangue Mountain Vegetation Reclamation on soil chemical properties underdifferent site conditions significantly affected, Robinia pseudoacacia, site condition onmodified coal gangue soil organic matter, total nitrogen, available potassium and the effect ofpH is best. Torch of site conditions, improve soil available phosphorus is best. But in theimprovement of the soil in the process of proper supplementary nitrogen source.
