淮河流域湿地的生态脆弱性特征研究

论文分析了淮河流域湿地的类型构成,从生态脆弱性的角度阐述了淮河流域湿地的脆弱性特征.指出了淮河流域湿地具有自然灾害频发的干扰性脆弱,湿地水资源紧缺的压力性脆弱,河道断流、湖泊干涸的灾变性脆弱,湿地水体污染严重的胁迫性脆弱,湿地生态系统面临退化威胁的衰退性脆弱和水土流失严重的波动性脆弱等特征.针对性的提出了流域湿地的可持续发展策略.

Discussion on the Ecological Vulnerability in the Wetland of Huaihe River Valley

Wetland plays an important role in the natural ecosystem.The component of the wetland was demonstrated in Huaihe River Valley(HRV),and the characteristic of the wetland in HRV is analyzed in ecological vulnerability.The results indicate that the wetland is frequently disturbed by natural hazards,the wetland is lack of water resources,the river branch often dry while some lakes often dry up,water pollution is serious in the wetland,the ecosystem of the wetland is facing the threaten of degradation,and the wetland undergoes the bad water and soil runoff.The above factors make the wetland more vulnerable in Huaihe River.The sustainable developing strategies also are pointed out for the wetland of Huaihe River Valley.
