深圳湾凤塘河口红树林修复工程

由于城市化影响及人为干扰,深圳凤塘河口水质受到严重污染,河口红树林生态系统严重退化。为了使凤塘河口恢复生态平衡,深圳市福田区启动了福田凤塘河口红树林修复示范工程。该工程设计以海陆交错带的生态修复为主题,通过水污染控制系统、水动力控导及生态修复等三方面内容建设,在海陆路交错带上构建红树林—水体(含水生植被)及红树植物—半红树植物—陆生植物/植被—隔离植被带大格局。此外,本文还分析了工程前水体及红树林生态系统现状,植被恢复工程的主题、原则、整体格局及工程技术,工程后的景观效果及生态环境状况。该工程的整体设计及工程技术可为同类工程提供参考。

The Ecological Restoration Project of Mangrove in Fengtang River Estuary of Shenzhen Bay

Due to the urbanization impact and human disturbance, the water quality of Fengtang estuary in Shenzhen was seriously polluted, and part of the mangrove ecosystem was badly degraded. To restore the ecological balance in Fengtang estuary, the municipal government of Futian district, Shenzhen city started the ecological restoration project of mangrove in Fengtang estuary, Futian district of Shenzhen city. Take the ecological restoration on the transitional zone between inter-tidal wetland and inland as the theme, this project built a vegetation series of mangrove -water system （including water vegetation） true mangrove - mangrove associates terraneous plants/vegetation segregated vegetation zone, by constructing the monitoring system on the work and water power, controlling system on water pollution, ecological restoration and landscape engineering. Furthermore, the status in quo of water quality and mangrove ecosystem before the project, the project theme and principles, the integrative vegetation pattern, the engineering technique of this project, and the landscape effect and ecological environment status after the project were also stated. The design theory and engineering technique of this project will provide important reference or implications for other similar projects in the future.
