摘 要 ：基于统一的湿地景观分类系统 ,利用遥感和 GIS技术 ,选择两个典型流域为研究单元 ,通过对比定量研究了 5 0年来流域湿地景观多样性的变化过程 ;分析了湿地景观多样性变化对生态系统多样性和群落多样性的影响以及与面积的关系 ;探讨了流域地貌类型对湿地景观多样性形成的影响以及地貌多样性与湿地景观多样性之间的关系 ;通过湿地多样性指数分析发现湿地景观多样性受人类影响的阶段性变化特征 ,为流域湿地保护和退化生态系统的恢复提供定量分析依据。

Abstract:Wetlands are among the most biodiversity richness areas in the world. Much research attention has been paid on community and species diversity rather than the landscape diversity and the relationships between landscape parameters and wetland biodiversity. In particular spatial changes of wetland areas and impacts of landscape changes on long-term wetland biodiversity have yet to be studied. Landscape diversity of any major wetland area has fundamental influences on the ecosystem diversities as well as the f...
