The abandoned field in the mining area is an important aspect of the land deterioration and also one of the significant environmental problems in today's world. From the point of the distribution of the coal resources, the abandoned field in the mining area is mainly dispersing over the semi-arid region. The influencing factors are comparatively complicated on the recovery of the soils in these areas, and the difficulties for the recovery are relatively bigger. This article aims at this environmental problem, and tries to make careful researches on the orders of the succession of the soil and vegetation in the abandoned field in the mining area of the semi-arid region, therefore proposes an important engineering theory on the ecological treatment, which has extremely important influences on the controlling of the water loss and soil erosion and efficiently bettering the ecological environment.This article takes the Fuxin mining area and Pingzhuang mining area as the testing areas, divides the field types on the basis of the researches of the devastating situation in the mining area, systemically tests the changes of the soil physical properties and soil nutrition in different types of fields. And on the basis of the survey and analysis on the growing situation of the vegetation of the abandoned field in the mining area, studies the distribution order of the vegetation in different types of fields. By studying the succession orders of the soils and the succession orders of the vegetation of the abandoned field in the mining area, and influences of different types of vegetation on the succession of the soils, the replanted vegetation types in different types of fields are confirmed. According to the features of the abandoned field in the mining area in the semi-arid region, this article also proposes the technical measurement for the vegetation recovery.
