| 摘 要： | 基于近海生态系统健康评价模型,以2011—2012年间海洋生态环境调查数据为基础,对大亚湾石化排污海域的生态系统健康状态进行了综合评价。结果表明:丰水期(2011年8月),大亚湾石化排污海域生态系统健康综合指数为0.808,健康状态为"好",空间分布为近岸海域健康状况好于远岸海域,其中底栖生物多样性综合指数是影响该海域生态系统健康的主要负面因子。枯水期(2012年1月),石化排污海域生态系统健康综合指数为0.767,健康状态为"一般",远岸海域健康状况好于近岸海域,浮游植物多样性综合指数和底栖生物多样性综合指数是影响该海域生态系统健康的主要负面因子。与2006—2007年相比,大亚湾石化排污海域生态系统的健康状况正向"一般"状态退化。

| Abstract: | Using the model of health assessment of a marine coastal ecosystem, we assessed the petrochemical sewage waters in Daya Bay using the ecological survey data of 2011 and 2012. The results showed that the ecosystem health comprehensive index (EHCI) of the petrochemical sewage waters of Daya Bay during the flood season (August 2011) was 0.808, suggesting that the ecosystem health was at a "good" level. Spatial distribution of EHCIs of inshore waters was higher than that of offshore waters, and the comprehensive biodiversity index of benthos was found to be the primary factor that negatively affected ecosystem health. The EHCI of the petrochemical sewage waters in the dry season (January 2012) was 0.767, suggesting that ecosystem health was at a "moderate" level. Spatial distribution of EHCIs of offshore waters was higher than that of inshore waters, and the comprehensive biodiversity indices of phytoplankton and benthos were found to be the primary factors that negatively affected ecosystem health. Compared to 2006 and 2007, health status of the petrochemical sewage waters in Daya Bay was deteriorating and changed from "good" to "moderate". |
