Abstract

Abstract:

Plant communities in Przewalskii Horse Reintroduction Area of Kalamaili Mountain Ungulata Nature Reserve in Xinjiang are investigated.Two-way Indicator Species Analysis Method(TWINSPAN) and Principal Component Analysis(PCA) are applied for classification and ordination.According to research results,there are 35 species,26 genera and 18 families of plants in Przewalskii Horse Reintroduction Area,which are mainly xerophyte and mesoxerophyte arbors,shrubs,herbs and other types of eremophytes.The dominant groups are Chenopodiaceae,Leguminosae,Poaceae and Asteraceae plants.They can be categorized into five vegetation-type communities.The main components of vegetation-type communities in this area respectively include Stipa capillata,Sagebrush,Ceratoides latens,Phragmites australis,Leymus racemosus,Salsola collina and Ephedra.

Key words: Kalamaili Mountain, nature reserve, plant community, TWINSPAN, PCA
