半干旱地区矿区废弃地土壤演化规律研究

o solve the problem of land deterioration in the abandoned field in the mining area, Aiming at this difficult problem, this article researches the soil succession order in abandoned field of the mining area in the semi-arid region. On the basis of generalized analysis of reclaim technology research and practice in domestic and foreign abandoned field in the mining area, this article analyses the problems of soil evolution in the abandoned field of the mining area in the semi-arid region. This article takes Fuxin mining area and Pingzhuang mining area as pilot areas, through systematically carries on the test for physical and chemical properties and the nutrient change situation of the pilot area soil, then obtains the soil succession order in abandoned field of the mining area in the semi-arid region.Finally chooses the appropriate species as the replanted vegetation and researches the mutual function between vegetation and soil.
