The investigations on the relation between the site factors and species diversity were carried out in this paper.The results were as follows:Firstly,there is a limit significant correlation between the canopy density and species diversity.Secondly,the positive correlation between Ca2+,pH,NO3-.Mg2+ with the species diversity was showed,and had established regression equation.Thirdly,the significant correlation between tree height and species diversity in the arbor layer was showed,but,the difference was no significant with the other layers.At last,the variety of DBH was complex,the significant correlation was showed between the S index and the DBH,but,no significant correlation was showed between the shrub layer and the DBH,the limit significan was also showed in the SP and PIE index of the herb layer.
