Abstract：Reasonable utilization and protection of forest resources in Baishilazi nature conservation area, analyzing the nutrients status and chemicalproperty of the forest soils in four different zones of the nature conservation area. The experiment result indicates: the PH of the soil in Baishilazi nature conservation area is acidity. The content of organic matter and nitrogen is rich;the content of pHospHorus is appropriate;the content of potassium is poor.Ranking the four different zones according to soil fertility from top to bottom is Erdaogou、Chibosong、Dalonggou、Xiaolonggou.In different forest stands, the soil nutrient is highest in mixed broadleaf-conifer forest, shaw is lower, Quercus Mongolica is lowest.
