Abstract:[Background] Human activities, such as mining, cause the changes nearby environment, especially soil nutrients. The research is to investigate the difference of soil nutrient content among 4 land use types:shrub land, mining land, nature grassland and farmland in Yijinhuoluo County of Ordos, Inner Mongolia.[Methods] Yijinhuoluo County of Ordos is located in E 109°45'-110°40',N 38°50'-39°50', in which there are 3 major types of soil:skeletal soil, aeolian sandy soil and chestnut soil. The sampling sites were determined based on the studied mining area, centered outward in ladder shape, and the proportion of the land use in total area. The soil samples were collected from 3 random soil profiles, each profile was divided into 0-10, 10-20 and 20-30 cm layers, three soil samples were collected and mixed from each same layer, the mixed soil sample was divided into four shares equally, and the soil sample shares were packed to the lab. The soil organic matter was analyzed with dilution heat method, and the soil total nitrogen, phosphorus, potassium were analyzed respectively with wet combustion method, Mo-Sb colorimetry and flame photometry. The data was processed by ANOVA.[Results] 1) The organic matter content and total N content were significantly different under 4 land use types in the Yijinhuoluo region, while there was no significant difference on total P content and total K content at depth from 0 to 30 cm (P <0.05). In the case of organic matter content, 4 land use types can be organized from high to low as following,farmland (7.63 g/kg) > nature grassland (4.91 g/kg) > shrub forest land (4.11 g/kg) > land use for mining (3.29 g/kg).The highest content of total N, P, and K were 0.39 g/kg (nature grassland),0.42 g/kg (nature grassland) and 26.23 g/kg (shrub forest land).The lowest content of total N, P, and K were 0.13 g/kg (land use for mining), 0.34 g/kg (shrub forest land) and 21.59 g/kg (nature grassland) respectively. 2) In soil vertical section, the organic matter gradually decreased with the increase of soil depth on mining land and nature grassland. The maximum organic matter content appeared in the depth of 20-30 cm both in farmland and shrub forest land. The total N and total P content of the all land use types had a decrease tendency with the increase of soil depth. There was no obvious change about total K content within different soil layer.[Conclusions] Soil total N and total P content of the 4 land use types are comparatively ideal, and the total N content and organic matter content are deficient. The total P content of farmland can meet the growth needs of main crops; however organic matter and total N content cannot meet the growth needs of major crops.
