摘　　要：在分析海门市蛎岈山牡蛎礁海洋特别保护区海域生态系统现状及特点基础上,构建了包含环境、结构、稳定性3个方面24个指标的海洋特别保护区生态系统健康评价指标体系,并采用熵权综合指数模型和模糊综合评价模型对保护区的生态系统健康状况进行评价及对比分析。熵权综合指数法评价结果表明,保护区生态系统处于健康趋向亚健康的状态;熵权模糊综合模型评价结果表明,保护区生态系统处于健康状态。由于模糊综合评价模型能反映保护区各生态要素的健康状况,其评价结论更趋近于保护区客观现状,更适用于海洋保护区健康评价。Based on analysis of the status and characteristics of the marine ecosystem of the Liyashan Oyster Reef Special Marine Reserve of Haimen,an ecosystem health assessment index system for special marine reserves is constructed consisting of 24 indices covering three aspects,i.e.environment,structure and stability.Health of the ecosystem of the reserve was assessed and analyzed by comparison,using the entropy comprehensive index model and entropy fuzzy comprehensive evaluation model.The former indicates that the ecosystem is turning from the state of health to that of sub-health,while the latter shows that the ecosystem is still quite healthy.As the latter may reflect health conditions of the various ecological elements of the reserve and yield conclusions closer to the status quo of the reserve,it is more suitable for use in health assessment of marine reserves.
