中文摘要：

盘锦双台河口湿地国家级自然保护区位于辽宁省盘锦市境内,是世界上最大的芦苇沼泽湿地。近年来该湿地开始出现退化现象,为了挽救湿地生命,保护宝贵的自然资源,从湿地存在与形成、发育及演化等方面分析,在充分吸收以往盘锦双台河口湿地的研究成果、总结各种评价方法研究进展的基础上,建立了湿地功能评价体系,制定了湿地功能等级划分标准,用层次分析法确定各指标权重,对湿地各项功能进行评分,计算湿地综合评价指数,由此评价湿地功能的优劣。结果表明：盘锦双台河口湿地功能等级属于一般一类,在各项功能中,湿地的环境功能最为重要。湿地对于生物栖息、污染净化、物质产生以及调节洪水都起到了至关重要的作用,对于供水、调节气候、科研教育、历史文化遗产以及养殖功能也起到了重要的作用,相比而言美学价值和娱乐功能的作用就显得不是十分突出。
