中文摘要：

将能够解决水环境中各项评价指标的不相容性、具有较高分辨率的物元可拓法引入到湿地水环境评价中,并基于盘锦双台河口湿地的生态环境和功能,以野外大尺度调查为研究基础,将湿地划分为核心区、缓冲区和实验区。2010年汛期、非汛期、冰封期各区水质综合评价的结果表明,核心区的水质属于Ⅲ级或Ⅳ级,好于缓冲区（Ⅳ级）和实验区（Ⅴ级）。综合分析各个监测指标的关联度等级可知,全磷分级均大于Ⅳ级,全氮分级均大于Ⅲ级,表明该湿地各分区水质可能存在不同程度的富营养化现象;为确保该湿地的水环境不再进一步恶化,应减少缓冲区生活污水的排放及实验区造纸厂废水的排放。

英文摘要：

The matter element analysis with high spatial resolution can solve the inconsistency of water environment quality evaluation indexes.Based on the method,the ecological environment and function of Shuangtaihekou wetland and the large scale field investigation,the wetland is divided into core area,infall area and outfall area.The results of water quality comprehensive evaluation shows that the water quality of core area belongs to level Ⅲor level Ⅳ,which is better than the infall area with level Ⅳ and outfall area level Ⅴduring flood season,non-flood season and icebound season in 2010.From the comprehensive analysis of relational grade of each monitoring index,it can be found that the classification of total phosphorus are all larger than level Ⅳ,the classification of total nitrogen are all larger than level Ⅲ level,which shows that the water quality of each division may exist different water eutrophication phenomenon in wetland.So the emissions of wastewater at infall area and the sewage emissions of paper mill at outfall area should be reduced in order to keep the water environment from further deterioration.
