[Method] To investigate the effects of reclaimed water from Yingtai Oil Production Plant on the wetland ecosystem, a comprehensive ecological assessment index of an artificial wetland in the west of Jilin Province was established to measure the ecological economic and social benefits. The quantitative evaluation on the ecosystem health and comprehensive ecological benefit of the artificial wetland were carried out from 2003 to 2010 and were measured by means of the square difference method. [Result] After eight years of irrigation by reclaimed water, the levels of ecosystem health and benefit of the artificial wetland improved from Grade IV to Grade II, and the ecological environment, economic and social development of the wetland tended to improve. [Conclusion] The results indicated that the use of reclaimed water for irrigation of wetland ecosystems was a suitable way to control drought in arid and semi-arid regions.展开更多
