Abstract

Abstract: The investigation was conducted from July to August in Saihanba Forest Farm in order to determine how the different factors of the larch plantation affect the plant diversity.On the basis of statistics of investigation data,effects of different factors on species richness,evenness and plant diversity were discussed.The results showed that altitude had significant positive correlation with S.Aspect had no relations withother factors.Slope had more significant positive correlation with D and Jsi than H and Jsw.The results demonstrated that the effects which were caused by slope were more sensitive to Simpson indexes.Density and cannopy density had more sensitive effects on Shannon-Wiener indexes than Simpson indexes.Age had significant positive correlation with S and H,but not Jsw.

Key words: species richness, plant diversity, evenness, Larch plantation, correlation, stepwise regression
