华北地区滨海湿地生态系统健康评价体系构建研究

Research on the Constructing of Huabei Region Coastal Wetland Ecosystem Health Evaluation System

以华北地区滨海湿地中的天津宁河七里海湿地为例,以PSR模型作为评价基础框架,运用可持续发展的理论、环境生态学、城市生态学、景观生态学等科学理论,结合社会经济资料收集、地面数据的采集与生态环境现状调查,应用层次分析法(AHP),在咨询专家意见的基础上,利用T L Saaty的标度法,构建了华北地区滨海湿地生态系统健康评价体系。体系由压力子系统、状态子系统、响应子系统构成,共筛选出三大类共计19项综合指标,其中压力指标6项、状态指标9项、响应指标4项。通过实际验证,该评价体系能客观地反映出湿地生态系统健康水平,可为环境管理部门的科学决策以及湿地的可持续发展提供技术支持,可供其他滨海地区湿地评价时参考。

Based on the Huabei region coastal wetland Tianjin Qilihai wetland as an example,taking PSR model as the evaluation framework,using the sustainable development theory,environmental ecology,urban ecology,landscape ecology,etc,with scientific theory of social economic data collection,data collection and the ecological environment situation investigation,application of analytic hierarchy process（AHP）,in consultation on the basis of expert opinion,using the method of T L Saaty scale-free,finally constructed in north coastal wetland ecosystem health assessment system.System by pressure subsystem,state subsystem,response subsystem and were screened in the three kinds of comprehensive 19 index,including 6 pressure index,9 state index and 4 response index.Through the actual test,the evaluation system to objectively reflect wetland ecosystem health level,but for the scientific decision of environmental management of wetland and sustainable development,and provide technical support in the coastal areas of other wetland evaluation and promotion.
