中文摘要：

随着全球环境问题日益凸显，湿地得到普遍关注，湿地研究成为热点。对湿地生态功能、研究内容、研究方法等方面进行了回顾、归纳。国内外学者对湿地开展了大量研究，主要研究重点方向为湿地退化及退化原因分析、湿地保护、恢复重建与管理、湿地与全球变化关系研究、湿地生态系统健康评估、湿地评价等领域。研究方法由过去仅局限于湿地特征描述的定性评价，发展到湿地定量、定位研究，3S技术和数学模型方法在湿地研究中得到了广泛的应用。

英文摘要：

As global environmental issues become increasingly prominent, wetlands get widespread attention and related research has become hot pot. This article has reviewed and summarized the ecological functions, research contents and methods about wetlands. Scholars at home and abroad have carried out intensive researchs, the em- phasis mainly on the analysis of wetlands degradation and the reasons; wetlands protection, recovery and man- agement; relationship between wetlands and global change; health assessment about wetlands ecological system; wetlands appraisal and so on. Reseach mathods have developed to quantitative and positioning level rather than lim- ited to the qualitative appraisal about wetlands feature descreption in the past, 3S technology and mathematical models have been widely applied in the study of wetlands. Progress and prospect of research on wetlands at home and abroad.
