Abstract:: The Tarim River is the longest inland river in arid areas of China. At the same time, it is one of ecological environmental vulnerable areas. The general manifestation is that desertification is deteriorating. Idiographic exhibitions are as follows.Land desertification,soil salinization,grassland degradation, and reduction in biodiversity. All of these seriously destroyed the foundation of regional social and economic sustainable development. Located at the upper reaches of the Tarim River, Alar irrigation area is reclaimed after 1950. With the expansion of irrigation area, Alar irrigation area becomes the largest new oasis in the Tarim Basin. Water quantity has been improved within oasis, but has reduced outward oasis. Based on the inquisitional data of sampling sites,the biodiversity of the natural plant community in Aral area is analyzed by adopting diversity index, richness index and evenness index.The results show that species in this area are poorer and the configuration of community is simple. Species diversity index and richness index of oasis-desert transitional zone are very low. From the above analyses and combining with the practical situation,a conclusion is drawn that the degeneration of plant community which under the people’s interference is generally exist in this area, especially in oasis-desert transitional zone.Effective measures should be taken to restore the natural plant especially in those transitional zone.
