Assessment on the Health of Coral Reefs at Weizhou Isl and
摘要
Abstract
Objective]Scientific judgment was made on the current situation of coral reefs in Weizhou Island,and its main cause was found out,in order to provide powerful basis to take effective measures for timely sustaining the health of coral reefs in Weizhou Island.[Meth-ods]According to the data derived from previous research and the survey results of this re-search,the indicator system based on HRHPI was used for the coral reef health assessment through analyzing ecosystem structure,ecological function,stress,and social ecomony.[Re-sults]Natural condition in Weizhou Island still can support the survival of hermatypic corals and the species richness of hermatypic corals remains normal but with decreaseing coverage, distribution scope,and biodiversity of coral reefs,espcially in shallow sea and some areas suf-fering severe human activity.The mortality rate of corals is higher than its recruitment rate.[Conclusion]Coral reefs at Weizhou Island are in the trend of degradation,which is believed to be resulted from overfishing,pollution,physical inj uries (crumbled by people trampling, anchoring,underwater engineering,etc.)and large-scale environmental changes (e.g.cli-mate change).关键词
