摘　　要：为了解双台河口湿地生态系统当前所处的健康状况,采用压力(Pressure)-状态(State)-响应(Response)评价模型,运用层次分析法对该湿地的生态系统健康进行综合评价。评价结果表明:湿地生态系统健康综合指数为0.6464,整个地区的生态系统25.92%处于很健康状态,21.42%属于健康状态,19.59%属于亚健康状态,15.31%属于一般病态,17.76%属于疾病状态。评价结果表明,双台河口湿地生态系统正处于亚健康状态。In order to understand Shuangtaihekou Wetland current ecosystem-health-status, Pressure-State-Response evaluation model and analytic hierarchy process were used to carry out a comprehensive evaluation of the wetland ecosystem health. The evaluation results showed that the wetland ecosystem health index was 0.6464, belonging to the sub-health level. In general, 25.92% of the entire ecosystem region was in a healthier state. Meanwhile 21.42% belonged to the state of health, 19.59% the sub-health state, 15.31% the general morbid, 17.76% disease states. So Shuangtaihekou Wetland is in a sub-health condition.
