英文摘要	Study the influence of different land use types on the stoichiometric characteristics of soil C, N, P, and explore its response to environmental factors. The research takes soils of 6 different land use types (shrub grassland, dry land, economic fruit forest, sparse forest, primary forest, and waste grassland) from the demonstration area for comprehensive control of karst rocky desertification in southwest China-Grand Canyon of Guanling Huajiang, Guizhou as the research object. The result shows that the C, N, and P contents of primary forest among the six different land use types are the highest, which are significantly higher than that of shrub grassland, dry land, economic fruit forest, and waste grassland. The C and N contents of waste grassland are the lowest, which are significantly lower than that of primary forest, sparse forest and shrub grassland, roughly represented as primary forest>sparse forest>shrub grassland>dry land>economic fruit forest>waste grassland. The C, N, and P contents show certain seasonal variations, which are higher in autumn than in spring. In addition, soil C, N, and P contents show a trend of decreasing with the increase of soil layer thickness, with obvious surface accumulation characteristics. The soil C:N of spring and autumn in 6 different land use types are lower than the national and global averages, and the C:P and N:P are much higher than the average value of karst soils in the same area, indicating that the soil in the study area is relatively sufficient in N but P is relatively lacking. Redundancy analysis shows that soil C, N and P in different land use types are affected. The main environmental factors for the change of stoichiometric characteristics are the human activity intensity, landform, and the slope. The research results will provide relevant theoretical support for the control of rocky desertification and vegetation restoration in southwest karst.
