Soil system is an important part of karst rocky desertification system，and the deterioration of soil quality is theessence of rockydesertification，so it is necessary to clear the soil nutrient conditions under different rocky desertificationgrades for the control of rocky desertification and restoration of ecologicalsystem.The succession of karst rocky desertificationwas divided into six grades:nil，potential，slight，moderate，severe，extremely severe，only four typical grades(nil，slight，moderate，severe)were analyzed in thisstudy.Research advances in the soil nutrients of karst rocky desertificationin recent years were reviewed in thispaper.Based on paperspublished，the current research progress on soil nutrient statusof different rocky desertification grades in Guizhou were summarized and analyzed.It was discoveredthat，1)with thedeterioration of rockydesertification，soil bulk density and soilsand(>0.05mm)content increased while soilclay(<0.001mm)contentdecreased，but there was no significant difference in clay content and sand content between different grades ofrockydesertification.2)Content of soil organicmatter，totalnitrogen(N)，totalphosphorus(P)and available nutrientsall showed as nil rocky desertification(ND)>slight rocky desertification(LD)>moderate rocky desertification(MD)>severe rocky desertification(SD)，and those soil nutrients content decreased by power function with the increase of rockydesertification grade，and the order of decay rate was ranked as organic matter>available P>alkaline hydrolysis N>total N>available K> total P，soil nutrients decreased most quickly from ND to LD.3)Organic matter and total N content were remarkable correlation with other factors of soil physical-chemicalproperties，and contribute greatly to soil fertility in rockydesertification areas，could be used as sensitivity indicators of the relationship between soil and rocky desertification.4)The effects of land use type on soil nutrients in karst rocky desertification region were obvious，the contents of soil organicmatter and total N under different land use type both listed in the order of forest land>grass land> agriculturalland.Thestructure of surface plant community and soil nutrients are closely related to the succession process of rockydesertification， so increasing vegetation coverage and developing organic fertilization are important for controlling rocky desertification andecological recovery in karst rocky desertification region ofGuizhou.
