摘要:
为推动城市河流保护修复和可持续性发展,该研究 在长江生态大保护规划背景下选取武汉段作为研究对象,引 入生态系统服务(ES)理论,基于ArcGIS软件和InVEST模型 工具集,筛选计算了代表研究区综合特征的5个模块(生物多样 性、微气候调节、水净化、审美质量、休闲与娱乐),并通过 可达性评估了其高值与人口之间的耦合度。结果显示区域ES 与人口的空间匹配较为失衡,呈现区段梯度变化趋势。根据耦 合度结果,建议划分4类优先区域,提出优化蓝绿空间格局和 构建蓝绿空间网络的建议,目的为均衡区域的ES存量和激活 ES流量。本研究的存量和流量测定评估体系能有效识别ES转 化的薄弱区,助力区域综合效益提升,为城市河流廊道的空间 优化提供参考。

Optimization Study of Riverside Blue and Green Space in Wuhan—A Perspective from Ecosystem Services Assessment
QIU Yue,WEN Chen,DAI Fei
Abstract:
: In order to promote the protection, restoration and sustainable development of urban rivers, this study selects the Wuhan section as the study area under the background of the Yangtze River Ecological Protection Plan, and introduces the Ecosystem Services (ES) theory to build an evaluation system. It includes 5 modules (biodiversity, microclimate regulation, water purification, aesthetic quality, recreation and ecotourism) based on ArcGIS and InVEST models. It assesses accessibility from high values of ES to high values of the population. The results suggest that the balance between ES and the population is destructed, and regional differences exist. According to the results, 4 types of areas are divided, and planning suggestions such as optimizing the blue-green spatial pattern and building a blue-green spatial network are put forward. This ES potential + flow evaluation system can effectively identify and optimize the priority areas, which may provide a reference for other cities in the future.
Key words:  landscape architecture  ecosystem services assessment  potential  flow  urban riverside  blue-green space
