主 题：Intra-community Stand spatial structure Comprehensive evaluation Topographical factor Forest vegetation
摘 要：Growing public awareness of the importance of protecting biodiversity requires the development of forest practices that increase the complexity of stand *** the ecological processes of different forest vegetation provide insights into community coexistence *** this paper,the spatial patterns of three different communities,evergreen broadleaf forest,deciduous broadleaf forest,and mixed needleleaf and broadleaf forest at ***,China,were quantified with four structural parameters,the mingling index,the uniform angle index,the diameter dominance index and the crowdedness *** trees with a diameter at breast height of more than 5 cm were *** analyses highlighted that most trees in the three communities were extremely dense and slightly clumped,with a moderate size differentiation and high mixed *** mixed needleleaf and broadleaf forest,the distribution pattern of tree species was better than the other two ***,spatial patterns in mixed needleleaf and broadleaf forest exhibited a strong stability-effect,that is,the stand had a suitable environment for the stable survival of the *** the increasing of elevation,the degree of the mingling index and the crowdedness index increased,however,there was no influence on the uniform angle index and the diameter dominance ***,at the same elevation,four structural parameters of shady slope were larger than that of sunny *** we found the relationship between stand spatial structure and environment factors had important influence on forest *** work contributes to the knowledge of population structure,and further provide theoretical basis for the sustainable development of forest resources and protecting biodiversity of Huangshan *** future studies,it is necessary to explore the limiting factors of community spatial distribution by combining species diversity and functional traits.
