摘要:
[目的]从景观格局的角度提出思路与方法以实现福州市生态用地的合理保护及布局优化,为统筹解决城市扩张与生态环境矛盾提供科学依据。[方法]通过生态重要性评价提取核心生态用地,运用构建生态安全格局的方法划定生态用地保护分区,并将分区方案与现行的生态保护红线方案进行对比分析。[结果]福州市核心生态用地类型以林地和水域为主,呈现出沿海-内陆分异的空间分布特征;与生态红线相比,生态用地核心区的优势在于景观破碎化程度低、聚集度指数更高,且整体景观的连通性较好,有利于生态系统最大化发挥其功能及效应。[结论]基于构建生态安全格局的思路方法对于落实区域关键性生态用地的保护更加科学合理,可对现有的生态红线划定形成有效的补充与完善,是优化生态用地保护格局、实现生态用地保护目标的有效途径。

Abstract:
[Objective] This paper studid the optimization of protecting the ecological land in a rational way in order to provide a scientific solution to the conflict between urban expansion and natural environment.[Methods] Fuzhou City was selected as the study area, this paper extracted the core ecological land through ecological importance comprehensive evaluation, then ecological land conservation zone was identified by utilizing the methodology of ecological security patterns. The conservation zone scheme was collated with the ecological protection red line which is currently administrated by the department of environment.[Results] The land cover type of the core ecological land in Fuzhou City was predominantly consist of forest and water area, and its spatial distribution emerged as a coast-inland pattern. In comparision with the ecological protection red line, the ecological land conservation zone had the advantage in the degree of landscape fragmentation and aggregation, and also with a better overall landscape connectivity.[Conclusion] Ecosystem services and ecological process would be more abundant and effective under the scenario of ecological land conservation zone. The method and conclusion from this example could not only supplement the technological process of the ecological protection red line but also improve its practicality, which is an efficient way of optimizing the ecological land protection and achieving government's goal.
