Resumen de Evaluation of ecosystem health in Futian mangrove wetland based on the PSR-AHP model

Haipeng Zhao, Gang Wang, Yingjie Song, Qiang Zhao

  • In view of the fragile ecological health of the Futian mangrove wetland ecosystem, an index system for evaluating ecosys-tem health of the Futian mangrove wetland was established based on the ‘pressure-state-response’ (PSR) model. Theecosystem health evaluation of the Futian mangrove wetland was carried out based on three aspects: pressure subsystem,state subsystem and response subsystem. Analytical hierarchy process (AHP) was used to determine the index weight.The index system is established and evaluated by the comprehensive index method. The results showed that the ecosystemhealth index of the Futian mangrove wetland was 0.25262. According to ecosystem health assessment criteria, it falls intothe ‘poor’ range. Based on our assessment, we consider that the structure and function of the Futian mangrove wetlandecosystem are degraded, that there has been a decline in biodiversity and that the prevailing environmental problems areserious. The results of this study can provide an effective scientific basis for the management of the Futian mangrovewetland ecosystem
