摘　　要：根据人工鱼礁区生态环境效应、生物群落效应和生态系统功能效应特征,构建北方资源增殖型人工鱼礁区生态系统评价指标体系。采用层次分析法确定各指标的权重,通过综合指数法构建生态系统健康评价模型,分析人工鱼礁区生态系统的健康状况。基于2010—2011年荣成俚岛人工鱼礁区和对照区每月生态环境的调查数据,运用构建的生态系统健康评价模型对荣成俚岛人工鱼礁区生态系统的健康状况进行评价。结果显示:人工鱼礁区与对照区的年平均生态系统的健康综合指数分别为0.647和0.614,二者不存在明显差异,均为健康状况良好的生态系统。综合分析认为,荣成俚岛人工鱼礁区生物群落仍处于发展阶段,需对该礁区进行长期连续的调查监测,以进一步了解人工鱼礁的投放对海洋生态系统和渔业资源增殖的影响。The eco-environmental, biological community and ecosystem functional effect were employed to build an assessment indicator system in stock enhancement artificial reef ecosystem. The analytical hier- archy process was used to determine the weight of each indicator. Ecosystem health assessment model was built with synthetical index method. This study assessed the ecosystem health of the stock enhancement artificial reef at Lidao Island, The City of Rongcheng in accordance with the ecosystem synthesizing as- sessment model. The assessment was based on the monthly survey between year 2010 to 2011 in the Lidao Island artificial reef areas and the controlled areas. The results showed that the ecosystem health index of the artificial reef and the control area was 0. 647 and 0. 614, respectively. Both areas were sub-healthy and not significantly different in health state. Both of the artificial reef areas were at good eco-environmental health condition. According to the comprehensive analysis, the artificial reef area biocoenosis at Lidao Is- land, The City of Rongcheng was still at a developing stage, thus needs to be surveyed continuously in or- der to understand more about the marine ecosystem influence and the stock enhancement function by the artificial reef.
