本文在总结国内外生态恢复成效评估相关研究的基础上，从环境质量、生物群落和景观格局三个方面选取相应指标，构建了一套系统的评估滨海湿地生态恢复成效的指标体系，并对厦门五缘湾的生态恢复成效进行了评估．结果表明，在恢复工程完成近5年后，五缘湾水体中无机氮、活性磷酸盐含量降低了70％以上；沉积物质量有了显著改善，沉积物各项指标均达到了一类标准；底栖生物由57种增加到87种，多样性指数由0.72上升到2.53．总体来看，五缘湾生态恢复措施成效显著．但同时也存在一些问题：由于硬质岸线取代了原有的滩涂，水鸟的种类减少了近40％；开发活动等人为干扰使得景观多样性和均匀度降低．

Based on the empirical studies home and abroad,an integrated index system concerning on the coastal wetland,which referred to environmental quality,biological status and landscape patterns,was established to eval-uate the ecological restoration in Wuyuan Bay of Xiamen.Results show that,after a five-year-long restoration,the dissolved inorganic nitrogen and active phosphate in seawater decrease by more than 70%.The sediment quality al-so improves remarkably with the dropping pollutants in sediments.All indexes of sediments have met the first class qualities set by the National standards.In addition,macrobenthos biodiversity increases significantly,with species number increasing from 57 to 87 and Shannon-Wiener index from 0.72 to 2.53.In conclusion,the implement of restoration project on the coastal wetland ecosystem in Wuyuan Bay gives rise to relative positive results.At the same time,several negative effects are emerged,for example,due to the replacement of hard shoreline with the o-riginal tidal flats,waterfowl species decrease by 40%.Furthermore,human disturbance has deteriorated the land-scape diversity and evenness.
