摘　　要：以大亚湾杨梅坑人工鱼礁区海域2007～2009年间6个航次生态环境调查数据为基础,运用所建立的生态系统健康综合评价模型对该海域生态系统健康状况进行了综合评价。研究结果表明:(1)人工鱼礁区生态系统健康综合指数平均为0.794,生态系统健康总体状况处于较健康水平;(2)投礁后人工鱼礁区生态系统的健康状况明显提高,6个航次生态系统健康综合指数分别为0.713、0.807、0.830、0.841、0.759、0.815;(3)不同季节,生态系统健康水平呈现一定变化,总体以春、夏季节健康状况略优于秋、冬季节:(4)影响该海区生态系统健康的主要因素为海水总无机氮和沉积物无机碳。研究结果对于人工鱼礁区生态系统的管理、保护和规划具有参考意义。An integrated health assessment was performed based on the data from eco-environmental investigations in the Yangmei Delve area in Daya Bay for six times during2007 to 2009. The results of assessment are as follows. （1） Ecosystem of artificial reef sea area was healthier, with an average integrated health index of 0.794. （2） Marine ecosystem of artificial reef area became much healthier after putting the reefs in the area, with the health indexes of 0.713, 0.807, 0.830, 0.841, 0.759, and 0.815 for six investigations. （3）The health indexes in spring and summer were better than those in autumn and winter. （4） The most important factors influencing ecosystem health were total inorganic nitrogen in sea waters and inorganic carbon in sediments. The assessment results should be very important for management, protection and planning of artificial reefs.
