多元目标导向下市域复合型绿地生态网络构建研究: 以泉州市中心城区为例

    Research on the Construction of Urban Composite Green Space Ecological Network Based on Diverse Objectives: A Case Study of the Central Urban Area of Quanzhou

    • 摘要: 多元目标导向下市域复合型绿地生态网络构建对消除快速城市化引发的负面问题, 提升区域生态系统服务能力以及发挥游憩、文化等多元功能具有重要作用。本研究以泉州市中心城区为例, 运用形态学空间格局分析(MSPA)、InVEST模型、最小累积阻力(MCR)模型和重力模型等技术手段判定生态、游憩和文化源地, 构建多类型网络与识别节点, 并提出多元目标导向下市域复合型绿地生态网络构建方法和优化建议。结果表明: (1)泉州市中心城区内生态源地共有20处, 构建了38条生态廊道, 识别出19个生态夹点、27个障碍点、10个踏脚石和132个断裂点。(2)筛选出28处游憩源地, 构建得到游憩廊道60条。(3)提取出167处文化源地, 构建主要文化廊道4条和识别文化发展片区7处。(4)生成112处复合景观节点和144条复合廊道。(5)提出节点保护建设、通廊载体打造与城市生态、文旅空间协同发展的优化策略, 进一步提升市域复合型绿地生态网络的综合效益。研究结果可为市域复合型绿地生态网络构建提供参考。

       

      Abstract: The construction of an urban composite green-space ecological network guided by diverse objectives plays an important role in addressing the negative impacts caused by rapid urbanisation, enhancing the regional ecosystem service capacity and supporting diverse functions such as recreation and cultural activities. This study takes the central urban area of Quanzhou as an example and applies morphological spatial pattern analysis (MSPA), the InVEST model, the minimum cumulative resistance (MCR) model, and the gravity model to identify ecological, recreational, and cultural sources, and to construct a multi-type network, identifying nodes, and suggesting methods and optimisation strategies for developing a composite green-space ecological network for the city that is guided by diverse objectives. A few of the key results of the study are listed below: (1) The central urban area of Quanzhou contains 20 ecological sources; 38 ecological corridors have been constructed; and 19 ecological pinch points, 27 barriers, 10 stepping stones, and 132 breakpoints were identified. (2) 28 recreation sources were identified, and 60 recreation corridors have been constructed. (3) A total of 167 cultural sources and 7 cultural development areas were identified, and 4 major cultural corridors have been formed. (4) A total of 112 composite nodes and 144 composite corridors have been constructed. (5) Optimisation strategies were proposed for the protection and construction of nodes, the creation of corridor carriers and the coordinated development of urban ecology and cultural tourism spaces, to further enhance the comprehensive benefits of an urban composite green-space ecological network. The study's results can provide references for the construction of an urban composite green-space ecological network.
