摘　　要：以生态系统健康及压力-状态-响应（PSR）模型作为研究方法，根据沿海湿地生态系统的特点，建立一套沿海湿地生态系统适用的健康评价指标体系。以现有研究数据和统计资料为基础，对长江口崇明东滩湿地进行单因子和综合评价，分别计算其健康度、压力综合指数和响应综合指数。揭示崇明东滩湿地的生态系统健康状况以及形成原因，并提出保护对策和可持续利用的相关建议。研究结果表明：①崇明东滩湿地生态系统的健康度、压力综合指数和响应综合指数分别为0．72、0．64和0．79，总体上仍处于一个较为健康的状态；②崇明东滩湿地生态系统目前的主要压力并不直接来源于土地围垦，而是来源于水环境污染和外来生物入侵。Ecosystem health and Pressure-State-Response （PSR） model is applied as research method in this article. According to the characteristics of coastline wetland ecosystem, a set of coastline wetland ecosystem health oriented assessment index system has been designed. Assessments, which aim at Chongming Dongtan coastline wetlands, were conducted not only with one single factor but on comprehensive scale as well. In the assessments, indices on health state （HSI）, pressure （PI） and response （RI） were calculated respectively. Results of this research disclosed the special distribution of health state of three wetland areas and the related cause. Meanwhile, suggestions on conservation and sustainable utilization are provided. （1）The health state of Chongming Dongtan stands in moderate condition and their detailed results of HSI, PI and RI are 0.72, 0.64 and 0.79 respectively; （2） The sources of wetland pressure were not originated mainly from land reclamation, but also from water pollution and biological invasion.
