摘 要:[目的]研究复层次群落下的油松-早熟禾、云杉-早熟禾以及落叶松-白三叶3种乔草群落的土壤理化性质,为复层次群落的乔草配置提供理论依据。[方法]对土壤含水量、pH、有机质含量进行测定。[结果]落叶松乔草群落下的土壤含水量高于其他2种乔草群落;土壤pH的排序为落叶松群落>云杉群落>油松群落;土壤有机质含量排序与土壤pH排序相同。[结论]土壤有机质含量越高,土壤pH越高,呈正相关性。这与底层地被植物的种类有着直接关系。豆科白三叶能够提高土壤pH和土壤有机质含量。[Objective] The research aimed to study the soil physical and chemical properties of multiple level community under Chinese pine-bluegrass,spruce-bluegrass and larch-white clover communities,and provide the basic theory for multiple level communities of tree-grass deploying.[Method] The soil water content,pH and soil organic contents were determined.[Result]The soil water content of larch tree-grass communities was higher than the other.pH sequence was larch communities spruce communities Chinese pine communities.The sequence of soil organic content was as the same as soil pH.[Conclusion] The higher soil organic content,the higher was pH.It indicated the positive correlation.It related the species of ground cover plants below.The leguminosae white clover could improve pH and soil organic content.
