金山三岛陆域生态系统健康状况分析评价

摘要

在对上海市金山三岛自然保护区陆域生态系统调查研究的基础上，采用层次分析法－综合指数评价模型对其进行生态健康状况评价分析。结果表明，该陆域生态系统综合健康指数（ CEI ）为0．648，保护区的生态质量一般，生态系统稳定性差，自我恢复能力不强。建议采取一定的人为干预措施来保护金山三岛陆域生态系统，使其朝更优的方向发展。%Based on the investigation and studies of the land area of Jinshan three-islands marine natural reserve in Shanghai , the authors use analytic hierarchy process-compound evaluation index model to estimate the ecological condition of the reserve.Finally, the composite evaluation index(CEI) was figured out as 0.648.The results showed that the environment system was not quite satisfying , with poor stability and recovery capability .It is suggested that measures should be taken to protect the ecosystem of the Three Islands for a better changes .
