The Study Of Stability Influence In ChangJi Oasis Ecosystem Under The Urbanization Process

The urbanization is a kind of inexorable trend of human societyeconomic development; with development of western regions constantlydeepened, the urbanization process of the of Xinjiang oasis is constantlyaccelerated, the urbanization level constantly improves of the oasis cityrepresentatives by Tianshan north slope economy zone, Changji oasis is thecenter area of Tianshan North Slope economy zone, under the drive of theinternational metropolis –Urumqi, the urbanization level in this area is farhigher than other areas of the whole boundary, and economic developmentis very fast, With the development of this area industry, social economy,Population's growth,the level of production of industry and agricultureconstantly improves, people have serious contradiction with land day by day,The question of water pollution, air pollution is outstanding day by day, Thetrend is obvious that the oasis ecological environment part improved andworsenned wholly, the resource ,environment, ecology of the oasis will facethe unprecedented enormous pressure, the negative effect that theurbanization process brings is more and more serious, and cause the furtherpotential threat to the stability of the oasis ecosystem.The implementation ofWu-Chang economic integration strategy certainly will produce greaterecological influence to ChangJi oasis.Seeing that the oasis ecosystem havethe characteristic such as is highly fragile, Systematic elasticity, the abilityto resist perturbation is low, the sensitiveness influenced to external world isstrong, bad of stability, It have important realistic meanings to accurate andobjective in time master the influence produced toward oasis ecosystemstability in Changji of the urbanization process,to safeguarding the stabilityin the oasis ecosystem,make the correct urban development tactics,promotethe health fast development of the regional economy, guarantee the oasis aredeveloped and utilized continuously forever.This research at first Have analysed the dynamic change of viewpattern of the Changji oasis, analysed the oasis urbanization processcharacteristic and threated to resource and environment of Changji oasisfrom the four parts about production, life, resource and environment in theoasis.On the basis of analyzing, Have drawn the suitable index from fourparts to built the Structure and appraise of the oasis ecosystem stabilityappraise system under the urbanization process,have made quantitativeanalysis and prediction to the oasis ecosystem stability influence by theurbanization.The result showing : (1)The oasis urbanization level in Changjiis relatively high,speed is fast,from 1986 to 2002, the urbanization level hasincreased by 10. 44 percentage points, the urban area has increased by 132.
