A correlation study of generation factors for forest landscape effects

Forest community structure is the physical foundation to form forest landscape effect.30 plots of landscape forest were selected in Chun'an,Jinhua and Dongyang Cities in Zhejiang Province by standard quadrat method,and their forest community structures and the forest landscape effects were measured.The forest community structure was represented by character factors such as species diversity,stand density,community richness,vertical layer,and distribution patterns of species groups.The forest landscape effect was represented by landscape factors including tree height,canopy density,under-branch height,coverage of grass-vegetation layer,colur reaction of stand,species composition,distribution of trees and leavings of felling.The correlation between forest community structure factors and forest landscape effect factors was analyzed.The results showed that each forest community structure factor had correlation only with a certain individual factor of forest landscape.Each forest landscapee effect factor was generated from correlated forest community structure factor;forest landscape effect was a synthesis reflection of the whole character of forest community structure and forest management situation.
