| Abstract: | Hongze Lake wetland(HLW) is a typical ecotone in Huaihe River Valley.This paper analyzes the main influential factors that make the HLW more vulnerable.Special topography and geology makes the HLW become basically vulnerable,while the transitional geographical location makes the HLW to be interactively vulnerable.Frequent flood and drought causes the Huaihe river to be vulnerable,biographical diversity is threatened by intimidation,and water in HLW also polluted because industrial development.Currently,irra... |
