Indicator system for assessing mangrove ecological degradation and a case study of the Zhangjiang Estuary

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.
