基于生态敏感性分析的生态控制线修编研究

Research on ecological control line revision based on ecological sensitivity analysis

生态控制线在保障城市生态安全,遏制建设用地的无序蔓延式扩张有着重要的作用。随着生态控制线被城镇建设侵蚀,生态控制线的划定和管理提出了更高的要求。生态敏感性评价作为应用广泛的技术方法,能够为生态控制线划定及修编提供科学有效的依据。以东莞市为例,通过生态敏感性评价分析,划分敏感性分区,提出生态控制线修编建议。

The ecological control line plays an important role in safeguarding urban ecological security and curbing the disorderly spread of construction land.As the ecological control line is eroded by urban construction,the delineation and management of the ecological control line put forward higher requirements.As a widely applied technical method,ecological sensitivity assessment can provide a scientific and effective basis for the delineation and revision of ecological control lines.Taking Dongguan City as an example,through the ecological sensitivity evaluation analysis,the sensitive zoning is divided,and the ecological control line revision suggestions are proposed.
