吉林省西部人工湿地生态系统健康与综合生态效益研究

目的]对吉林省西部人工湿地的生态系统健康状况和综合生态效益进行评价。方法]以吉林西部人工湿地为研究对象,考察了英台采油厂中水灌溉对湿地生态系统的影响,从生态环境、经济和社会发展角度构建了人工湿地综合生态效益评价指标体系,并采用均方差法对2003～2010年吉林西部人工湿地生态系统健康和综合生态效益进行定量评价。结果]经中水灌溉的人工湿地运行8年后,生态系统健康等级由Ⅳ级（退化区）转变为II级（近自然区）;人工湿地的综合生态效益等级由IV级改善为II级,经济、生态环境和社会发展已趋于完善。结论]在干旱、半干旱的湿地地区,采用中水灌溉恢复生态系统是一种＂以废治旱＂的适宜途径。

Study on Ecosystem Health and Comprehensive Ecological Benefit Assessment of the Artificial Wetland in Western Jilin Province

Objective] The research aimed at assessing the state of ecosystem health and comprehensive ecological benefit of the artificial wetland in western Jilin. Method] Taking an artificial wetland in the west of Jilin Province as the research object,in order to investigate the effects of reclaimed water from Yingtai Oil Production Plant on the wetland ecosystem,a comprehensive ecological assessment index system of the arlifieial wetland was established from the aspects of ecological environment,economic and social development. Afterwards,the quantitative evaluation on the ecosystem health and comprehensive ecological benefit of the artificial wetland in western Jilin from 2003 to 2010 were carried out by means of square difference method. Result] Ater running eight years,both the level of ecosystem health and comprehensive ecologieal henefit of the arlificial wetland improved from Grade Ⅳ to Grade Ⅱ,and its ecological environment ,economic and social development tended to be perfect. Conclusion] In arid ard semi-arid wetland,adopting reclaimed water to irrigate to restore wetland ecosystem is a suitable way by using wastewater to control drought.
