Abstract:

Using the "pressure-state-response (PSR)" model,this paper constructed an evaluation index system for the degradation degree of mangrove wetland ecosystem in Hainan according to the causal logical relationship of mangrove wetland degradation.Combined with the status and characteristics of Hainan mangrove wetland ecosystem,23 evaluation indicators were screened out,and three typical mangrove wetland ecosystems in Hainan were selected to evaluate the degree of degradation.The results showed that the three mangrove wetland ecosystems in Hainan had different degrees of degradation.The Dongzhaigang mangrove and Bamenwan mangrove were in mild degradation,while the Huachangwan mangrove was in moderate degradation.

Key words: mangrove, degradation grade, PSR model, Hainan Province
