【摘要】 通过总结目前红树林面临的各类生态退化机制,利用"压力-状态-响应(PSR)"分析模型,构建了红树林生态退化机制评估指标体系,并应用于福建省漳江河口红树林生态系统的案例研究.评价结果显示:漳江河口红树林生态退化压力仍处在较小的范围内,主要压力源来自生物入侵以及海岸带水产养殖和围垦;对影响显著的生态退化因子已经采取了有效的控制措施;保持并加强保护措施,将有助于当地红树林生态系统在未来维持稳定的状态.更多还原

【Abstract】 An assessment indicator system was constructed based on a summary of various mangrove ecological degradation mechanisms using a ’Pressure-State-Response(PSR)’ model.This model was then applied to a case study of mangroves in the Zhangjiang Estuary of Fujian Province.The results showed that the mangrove is facing small ecological stress that mainly stems from alien species invasion,coastal reclamation and aquaculture.Several influential ecological degradations have been effectively controlled by conservation measures,which will contribute to maintaining the stable state of the mangrove in the near future.更多还原
