摘要：

Distribution characteristics of soil phosphorus availability and its correlations with plant species diversity in the forest ecosystem of Mt.Jinyun are studied in this paper.The results are as follows:①Available P of soil profile in different communities has an evident gradient,i.e.,A(humus layer)>B(deposition layer)>C(parent material layer).②Except for shrub-grassland,soil available P content orderly increases along the successional directions,i.e.,Pinus massoniana forest<P.massonia-Symplocos setchuensis mixed forest<evergreen broadleaved forest.③Different degree's of correlations exist between soil available P and plant species diversity.The correlation between tree diversity and available P content of A and B layers is very significant.
