中文摘要	The aim of this study was to characterize the diversity of artificial vegetation and provide evidence of reasonable distributional patterns for the artificial wind-breaking and sand-fixing forest in the periphery of oasis, in the lower reaches of the Tarim River, Xinjiang, China. The species diversity of artificial-natural plant community four years later was calculated by the measurable description of species richness index, Simpson index, and Shannon-Wiener diversity index, community evenness. The main results are as follows: (1) The artificial-natural communities are formed since several native species naturally occurred or invaded to the artificial communities in four years. (2)The species diversity is obviously increased in the artificial-natural communities. And there are all 26 species belonging to 12 families, 25 genera in the study communities, including 3 species of arbor, 9 species of shrub or semi-shrub, and 13 kinds of herbage, 1 vine species. (3)The variety range of Shannon-Wiener index (H') is 2.08-3.99 in 9 communities, and its trend is similar to that of richness changes. (4)Comm. Halogeton glomeratus+Karelinia caspica has the highest diversity and evenness indices while Comm. Calligonum caput-medusae+Populus euphratica is on the contrary. The results may provide the relevant theories for the further optimization species composition of the wind-breaking and sand-fixing forest and enhancement the stability of artificial plant community in the ecological fragile area.
