| 摘 要： | 随着海岸带开发的不断增强，天津市大神堂牡蛎礁海洋特别保护区的生态环境面临严重威胁。为了全面准确地表述该区域的生态状况，充分考虑牡蛎对重金属的生物富集作用、保护区生态系统的脆弱性及捕捞行为对牡蛎可持续增长的重要影响，构建了牡蛎礁特别保护区生态系统健康评价体系，并基于模糊综合模型对该区域的生态系统健康进行了评价和研究。结果表明，特别保护区的底质与水体处于健康状态，生物环境和捕捞压力处于不健康状态，整体健康状态不容乐观；在时空分布状态上，存在远海优于近岸、南部优于北部，并随时间的推移整体改善的趋势。所构建的牡蛎礁特别保护区生态系统健康评价体系是对现有评价体系的有益改进和补充。

| Abstract: | With dramatic development in the coastal zone of the Dashentang oyster reef marine special reserve in Tianjin, its ecological environment has been facing a serious threat. To describe the accurate and comprehensive condition of ecosystem health in this region, a new ecosystem health evaluation system is constructed in this study fully considering its bioaccumulation of heavy metals by oysters, vulnerability of ecosystem, and high impact of harvesting on the sustainable growth of oysters. And its ecosystem health is evaluated and examined using a comprehensive fuzzy model. The results show that the biological and fishing system in this fast developing region is unhealthy, although its benthic substrate and water quality are in good condition. In temporal and spatial distributions, the ecosystem heath tends to improve from near-shore to off-shore and has been getting better overall over time. This ecosystem health evaluation system is an improvement and supplement to the existing system. |
