The Plant Community Quantitative Analysis Of Baerluke

Community succession occupies an important position in the process ofecological disciplines. Community succession theory is widely used in the practiceof species conservation. Baerluke mountain Amygdalus ledebouriana NatureReserve is located in the Xinjiang Uygur Autonomous Region Yumin county. Theprotected area is to protect the Amygdalus ledebouriana, Malus sieversii and otherrelics of the Tertiary larvae for the purpose of. Research community succession onprotected areas for the protection of Amygdalus ledebouriana, Malus sieversii andother plants provide a theoretical basis.In this paper, by the plant quadrat survey of Nature Reserve, use of the quadratdata collected from, take quantitative analysis of plant communities of the study area.Use Jaccard similarity coefficient and the Pearson similarity coefficient make aclustering analysis on the composition of the quadrats and species, By The quadratproperties and environmental factors, Sort the quadrat and species by usingcorrespondence analysis (CA), detrended correspondence analysis (DCA), canonicalcorrespondence analysis (CCA)and DCCA.The results show that:1. In the study area plant community types can be clearly divided into threekinds;2. In the same enviroment, the species composition of quadrats are same orsimliar;3. Environmental factors such as elevation and aspect take greater influence on Speciesdistribution.On the basis of the results of previous studies, combined with the analysis ofthis article, Climate climax community of the region is Picea schrenkiana forest.The plant community succession of this region as follows: from xerophyticsemi-xerophytic herbaceous plant communities and shrub community succession toconiferous forest communities.
