围填海工程对湄洲湾海湾生态系统稳定性的影响研究

为有效防控围填海活动对海洋生态环境的影响，文章依据相关技术导则，以生境、生物和生态系统压力为指标，基于海洋生态环境调查结果，评估围填海工程对湄洲湾海湾生态系统稳定性的累积影响，并提出建议。研究结果表明：随着围填海活动强度持续增强，2010-2013年湄洲湾的海洋生态环境明显恶化，海湾生态系统稳定性指数总体呈下降趋势，自2012年起达到严重受损的程度；应严控湄洲湾海域的大规模围填海活动，重点关注渔业资源和底栖生物的生境恢复，同时优化技术导则中的初级生产力赋值。

The Impact of Reclamation on the Stability of Ecosystem in Meizhou Bay

In order to effectively prevent and control the impact of reclamation activities on the marine ecological environment, according to the relevant technical guidelines, taking the pressure of habitat, organisms and ecosystem as the index, and based on the survey results of marine ecological environment, this paper evaluated the cumulative impact of reclamation projects on the stability of Meizhou Bay ecosystem, and put forward some suggestions. The results showed that with the increasing intensity of reclamation activities, the marine ecological environment of Meizhou Bay deteriorated significantly from 2010 to 2013, and the stability index of the bay ecosystem showed a downward trend, reaching the degree of serious damage since 2012. We should strictly control the large-scale reclamation activities in Meizhou Bay, focus on the habitat restoration of fishery resources and benthos, and optimize the assignment of primary productivity in the technical guidelines.
