Abstract:

Water resource plays an important role in supporting the human society and the economic development.With an accelerating process of urbanization,contradiction between the urbanization and water environment is becoming prominent.In the present research,with the support of GIS technology,a spatial statistical method was used to establish water resources stress intensity (WRSI) model to explore the response of urbanization pattern around the Poyang Lake to the aquatic environment stress.The results are mainly as follows: (1)The Poyang Lake Area can be divided into three parts,i.e.core zone (0.412),marginal zone (0.807) and peripheral zone (-0.072).With the increase of the distance from the Poyang Lake,the urbanization level increases first and then decreases,demonstrating the important role of aquatic environment during the urbanization process.(2)Water quality exerts significant stress on the  urbanization,lower urbanization level under worse water quality,while higher urbanization level under better water quality.(3)Water amount exerts significant influence on  urbanization levels in the marginal and peripheral zones.The aquatic environment stresses on the urbanization are obviously different between the marginal and peripheral zones,the stress of water environment on urbanization  increases with the increase of distance from the Poyang lake
