摘　　要：运用压力-状态-响应(pressure-state-response,PSR)模型,采用生态系统健康理论评价珊瑚礁生态状况.借鉴国内外现有生态系统评价方法,结合珊瑚礁生态系统的特点,建立适合我国国情的珊瑚礁生态系统评价方法和模式,并对我国典型海域珊瑚礁生态健康状况进行评价,以期为我国典型珊瑚礁生态系统健康状况提供基础资料.评价结果显示东山、涠洲岛、海南东部珊瑚礁生态健康状况为健康,徐闻和西沙海域珊瑚礁生态健康状况为亚健康,评价结果与我国相关生态监控区调查结果基本一致.This research assesses the coral reefs＇ ecological status with the ecosystem health theory and PSR （pressure-state-response） model. Based on the extensive reviews of the ecosystem evaluation methodology in and abroad and taken features of coral reefs＇ ecosystem and China＇s environments into consideration, methods and modes are developed for the evaluation of coral reefs＇ ecosystem and their health in typical maritime space besides data provision. The results show that coral reefs around Dongshan, Weizhou Island and to the east Hainan Province are healthy and coral reefs around Xuwen and Xisha Islands are under the status of sub-healthy. The evaluation results are basically the same as the results from the investigation in related ecological monitoring area.
