摘要：

摘要：为合理利用与保护白石砬子自然保护区森林资源，对该四个地区不同林分类型土壤化学性质与养分状况进行了研究，结果表明：白石砬子地区土壤pH值呈酸性。有机质和全氮含量丰富；全磷含量适量；全钾含量贫乏。四个地区土壤肥力从高到低依次是二道沟、赤柏松、大龙沟、小龙沟。不同林分类型中，针阔混交林土壤养分最高；杂木林次之；蒙古栎林最低。

Abstract:

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.
