Soil physiochemical properties for 7different landuse types were investigated in the typical karst rocky desertification area of Lingyun City,Guangxi Zhuang Autonomous Region.Results showed that different landuse systems had significant effects(p <0.01)on the bulk weight,water content,total porosity,capillary porosity and non-capillary porosity,as well as the organic matter,total N,P and K,effective N,P and K,and exchangeable Ca²⁺.Compared with the soil in broad-leaf forest,the degrees of soil degradation in shrub land,coniferous forest land,fallow terrace farmland,grassland,fallow sloping land and farmland became serious in turn.Among them,soil quality was he worst in farmland and it was in middle in coniferous forest land,grassland,fallow sloping land and fallow terrace farmland,while it was better in shrub land and broadleaf forest land.Human disturbances were the dominant factor affecting soil physiochemical properties. Hence,the degrees of soil degradation were changed with disturbance intensity.It is significant to control unreasonable disturbances and restore good vegetation for soil quality improvement in the region.
