Soil properties of healthy,sub-healthy and unhealthy Pinus yunnanensis secondary forest were measured and their correlation with the health conditions of Pinus yunnanensis forest were *** results revealed that,the soil water content,bulk density,porosity,sand content,cosmid content,CEC and radily available K content changed regularly with the health condition changes of Pinus yunnanensis *** analysis revealed that,there were positive correlation between soil water content,porosity,cosmid content,CEC,radily available K content and health conditions of Pinus yunnanensis forest;and negative correlation between bulk density,sand content,meal content and health conditions of Pinus yunnanensis *** stepwise regression analysis,the regression models about health conditions of Pinus yunnanensis forest and soil properties were established.
