摘　　要：为研究我国典型滨海湿地环境评价方法,利用卫星遥感技术,结合地面生态调查,构建了以自然湿地面积比例、人工岸线比例等8项因子共同组成的指标体系,通过层次分析法和专家打分法进行权重赋值后,阐述了数据处理和计算的主要流程,提出了滨海湿地环境指数CWEI的概念和表征意义。应用上述方法对江苏盐城湿地珍禽国家级自然保护区进行了典型示范评价,结果表明该方法能够较好地反映滨海湿地环境状况与变化趋势。This paper studies the environmental assessment method of typical coastal wetlands in our country based on satellite remote sensing technology and ecological survey.An index system was built containing eight factors including natural wetland area ratio,artificial shoreline and so on.After weight assigment by the hierarchy analysis and expert evaluation,the main procedure of data processing and computing was described,and the concept and meaning of Coastal Wetlands Environment Index（ CWEI） was put forward. This method was then applied to a typical evaluation in Yanchen Wetland National Nature Reserve.The results showed that this method reflected the state and trend of the environment of coastal wetlands,and has a certain significance for the environmental assessment and protection of coastal wetlands.
