    Abstract:

    [Objective] We aim to understand the spatial distribution law of soil nutrient in Pingshuo mining area in Shuozhou City, Shanxi Province, in order to provide the basis for fertilization decision in the future, and to accelerate the improvement in soil condition in mining area. [Methods] We took Pingshuo mining area as the research area, and collected 30 groups of soil samples respectively from mining undamaged areas, mining damaged areas and harnessing areas. The soil nutrient content was then measured by experiments and analyzed by R and Sufer, to obtain nutrient changes in different areas. Finally, the soil nutrient status was comprehensively evaluated based on the membership value and weight coefficient of each nutrient factor in the sample. [Results] Compared with soil nutrient content grading and the standard of nutrient abundance and deficiency, the nutrient was in a status of deficient or acute deficient in Pingshuo mining area. Except for pH value, the variation coefficients and content of other nutrient indexes fluctuated greatly, especially in the undisturbed areas. Although land reclamation could improve the damaged soil of the mining area to a certain extent, it would take a long time for the damaged soil to be recovered to the status before mining. [Conclusion] Mining and land reclamation in Pingshuo mining area have important influence on soil nutrient content and distribution.
