摘要:
太湖流域湖荡湿地影响着整个流域生态系统的健康运转,是湖泊水体与陆地之间的过渡带,对周边城市的生态环境起到重要的净化调节作用,对太湖流域湖荡湿地生态系统健康进行评价,有利于湖荡湿地的科学管理,从而实现湖荡湿地资源的可持续利用.本文选择太湖流域11个典型的湖荡湿地为研究对象,于2012-2015年开展周年湿地观测季度调查.利用主客观组合赋权方法,结合太湖流域自然条件和社会功能,提出了基于生态可修复性指标的太湖流域湖荡湿地生态系统健康评价体系和方法.结果表明:太湖流域湖荡湿地中生态系统健康等级为优的占27.27%,分别是傀儡湖、尚湖和钱资荡;生态系统健康等级为良的湖荡湿地占9.09%,为长荡湖;中等生态系统健康水平的湖荡湿地居多,占36.36%,分别是阳澄湖、昆承湖、元荡和淀山湖;生态系统健康等级为差的湖荡湿地占18.18%,分别是滆湖、澄湖和宜兴三氿.本研究建立的湖泊生态健康评估体系和湖泊生态健康评价结果对太湖流域湖荡湿地的后续有效管理具有重要的现实意义.

Abstract:
Taihu Basin, the transitional zone between the land and the lake, influents the health of the whole river basin ecosystem, and plays an important regulatory role in the purification of the surrounding city ecological environment. The health assessment of wetland ecosystem in Taihu Basin is advantageous to the scientific management of lake wetland, so as realizing the sustainable utilization of float lake wetland resources. In this paper, water quality were investigated based on 11 typical lake wetlands of Taihu Basin during the period of 2012-2015, and try to build a method of the health assessment of wetland ecosystem in Taihu Basin, which considered the method of subjective and the objective weight-deciding, combined the natural condition with social function of Taihu Basin and propose ecological repairable index creatively. The results showed that Lake Kuilei, Lake Shang and Lake Qianzi are the lake wetlands with excellent healthy ecosystem in the Taihu Basin. The healthy level of Lake Changdang ecosystem is good. There are some lake wetlands with the middle healthy level in the Taihu Basin, such as Lake Yangcheng, Lake Kuncheng, Lake Yuandang and Lake Dianshan. Lake Ge, Lake Cheng and Lake Sangui are in the poor healthy level. The lake ecological health assessment system and lake ecological health assessment results established in this paper are of great practical significance for the management of lacustrine wetlands in Taihu Basin.
Key words:  Taihu Basin  lake wetlands  ecosystem health assessment  comprehensive health index
