摘  要:
洪泽湖湿地具有地质地貌基底性脆弱、南北气候过渡带影响的界面性脆弱、旱涝灾害频繁的波动性脆弱、生物多样性面临胁迫性的脆弱、水质污染的介入性脆弱以及人类不合理活动频繁的干扰性脆弱。AHP层次分析法评价结果显示:洪泽湖湿地的生态脆弱性综合指数为3.155 4,已呈显著的中度脆弱。评价结果同洪泽湖湿地脆弱性分析特征具有较好的一致性。

摘  要:
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.
