- 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,irrational human activities play a bad role in the HLW that causes the wetland to be vulnerable easily.We set up a scientific index system to appraise the ecological vulnerability in HLW by AHP.The ecological vulnerability degree result is 3.155 4,which shows that the HLW is in a state of being moderately vulnerable.The result also shows a nice consistency with what this paper analyzed as above.
