生态系统健康作为重要决策依据,能减少决策失误导致生态破坏和生态风险。但由于存在评价指标筛选难、权重难确定,评价基准操作复杂或不科学,现有综合评价方法不合理等问题,海岸带较高层次决策中系统有效的生态系统健康评价技术路线较少。本文提出基于多维决策(MddM)的生态系统健康评价技术路线能有效解决以上问题,其主要步骤包括应用所有数据评价生态系统生物成分和功能要素,专家参与生态系统健康评价以及生态与决策方案之间[影响、置信度;关系]评分,以支持决策。最后将该技术路线应用于厦门湾海岸带地区主体功能区划案例研究中。研究结果表明:厦门湾海岸带地区生态系统整体健康状况中等,从生态维度来看,更支持旅游作为厦门湾海岸带地区主体功能。The assessment of ecosystem health is important for decision-making process to avoid ecological damage and risk.There are few systematic and effective approaches of applying Ecosystem Health Assessment(EHA) into high-level decision making process because of the difficulties including indicators selecting and weighting,the complexity of establishing the reference,and lacking of integrative assessing methods.To fill this gap,a new approach of EHA based on Multi-Dimensions Decision Making(MDDM) model was developed to support high-level decision making process in coastal zone.The MDDM-based EHA approach is as follows:all collected data of ecosystem were collected to assess biological elements and ecological functions;expert judgment method was applied to assess entire ecosystem health status and to grade [Impact,Confidence;Relationship] which links ecological dimension and the alternatives of decision-making.The approach was applied in the principal function zoning in Xiamen coastal area.The results showed that the current ecosystem health status in Xiamen coastal area is mediate,and tourism should be the principal function rather than harbor transportation from the perspective of ecosystem health.国家海洋公益性科研专项课题(200905005); 2011年度“厦门大学基础创新科研基金”(中央高校基本科研业务费专项资金)项目(2011121008
