大亚湾生态环境问题及其调控策略

主要阐述了大亚湾现存的生态环境问题及其调控策略.大亚湾生态环境的退化现状与特征主要表现为:生态系统结构遭到破坏、生物群落组成明显小型化,生物多样性降低,生物资源衰退;红树林和珊瑚礁面积锐减,生态服务功能衰退,沿岸滨海湿地萎缩;生物生境遭破坏导致生物量下降;营养环境恶化导致赤潮频发.并就因开发建设等人类活动对该区域海洋生态环境的影响,提出了调整和控制各种开发活动,为受损海湾生态环境的修复重建和持续利用的参考建议.

The Daya Bay Ecological problems and corresponding controlling strategies

The ecological problems and corresponding controlling strategies for the Daya Bay are introduced in this paper. The characteristics of degraded ecosystem in the Daya Bay are as follows. Ecosystem structure is destroyed; biological community is miniaturizing; biodiversity is simplifying; biological resources are declining; ecosystem services of mangroves and coral reefs are declining; coastal wetlands are decreasing; biomass is declining as a result of habitat deterioration. More and more red tide events occur due to nutrition environment deterioration, etc. This paper discusses the impact of human activities on the marine ecosystem of Daya Bay, and proposes some suggestions for restoring, reconstructing and making sustainable utilization of the damaged coastal ecosystem.
