The Stress Of Water Environment On Urbanization In The Region Around Poyang Lake

With the development of urbanization in China,the stress of water environment on urbanization is more obvious than before,it has become a focus by relevant departments.So it is pressing and necessary to research the laws of water environment stress urbanization so as to control the water stress,in order to promote the social development.The paper choose the cities surrounding Poyang Lake as the research objects and analyse the laws of the stress of water environment on urbanization and analyse the relation between the water environment and urbanization emphatically.At first this paper analyse the current situation of the water enviromnt and urbanization of Poyang Lake.What is more,the paper analyse the stress relation between water and urbanization by using the space statistical methods (spatial autocorrelation). On the base of fatter,the paper analyse the stress rule of the water environment on urbanization by building the water environment stress model.The results show that:(1) there is positive autocorrelation between water quality and urbanization in the core region around Poyang Lake.But the autocorretion of urbanization is weak.It can found that there is obvious relation between water quality and urbanization with space relevance G statistical method and it finds that there is obvious correlation between water quality and urbanization.(2) From the analysis of the relationship between water environment and urbanization,it finds that water stress urbanization in peripheral zone is more higher than its in the fringe area in the region Poyang Lake. In the water shortage region,the urbanization level is lower than the water rich region.That is confirmeds:water environment stress urbanization.(3) From the analysis of the laws of water stress urbanization,it finds that the water stress is different in the same buffer;on the whole,the water stress is more powerful in the peripheral zone than fringe zone.That is to say, we can draw a conclusion that if the city more far from Poyang Lake then the water stress is more fierce.
