Abstract
Species richness,species diversity index and evenness index of six forest landscape types in Wuyishan Scenery District including Pinus massoniana forest,Cunninghamia lanceolata forest,economic forest,bamboo forest,broad-leaved forest and Camellia sinensis plantation were discussed by using the sampling data.The results show that species richness is different with types of vegetation in six forest types.Species richness of shrubs is higher,whereas those of trees and herbs are lewer,and the vertical structure of species richness is in the following order:shrubs＞trees＞herbs in most forest types.The differences of species diversity among the six forests are significant,and the order of species diversity is broad-leaved forest＞Pinus massoniana forest＞Cunninghamia lanceolata forest＞bamboo forest＞Camellia sinensis plantation＞economic forest,which accords with the general law of the variety of species diversity:natural forest＞half artificial forest＞artificial forest.The results of species diversity of different stages in Pinus massonianaforest indicate that species diversity is increased with the succession of forest.Comparison of species diversity in the Wuyishan Scenery District with that in other areas shows that Wuyishan Scenery District is an area with a very abundant plant diversity.
