洪泽湖湿地生态脆弱性的理论与实践

Theoritical and Practical Discuss on Ecological Vulnerability in Hongze Lake

近年淮河流域洪涝灾害的频发,使洪泽湖湿地生态脆弱带区域受到越来越多的关注。分析了生态脆弱性的内涵、机理、特征以及其脆弱性的成因,主要表现在地貌基底的脆弱性、过渡带界面的脆弱性、旱涝灾害交替波动的脆弱性、水质污染的介入性脆弱,以及人类活动综合影响的干扰性脆弱。

Frequent flood hazards in the Huaihe river attracted more focus on the transitional zone of the Hongze lake wetland. This article explained the concept of ecological vulnerability zone, analyzed its mechanism and characteristic. As for the practical area of Hongze lake wetland, we believed its main causes for its vulnerability consists of the following five aspects： fundamental geomorphological formation, transitional zone for the north subtropical and the south temperate zone, fluctuation of the drought and flood hazard, water pollution of its drainage, and the comprehensive effect of human disturbance.
