Abstract: In this paper,the natural vegetation in the edge of Karamay Artificial Forest for Carbon Dioxide Capture was taken as a research object and the species composition,habits and importance values of natural vegetation were analyzed.The results show that the most abundant species was Chenopodiaceae plants,and the second was Zygophyllaceae plants in the edge of Artificial Forest for Carbon Dioxide Capture.Tamaricaceae was the least species in the edge of artificial forest.Because of the biological characteristics and ecological characteristics of Chenopodiaceae plants,relative density,relative dominance,relative frequency and importance values took the highest position in the community.The plant community structure is simple in the research area,but with a serious advantage phenomenon.

Key words: peripheral, natural vegetation, quantitative characteristics
