Abstract

This article investigates how to make the implementation of blue-green infrastructure (BGI) more attractive to solve urban problems in densely occupied watersheds that lack flood control and environmental quality protection infrastructure. Considering the obstacles related to implementing multifunctional solutions in developing countries, measuring its co-benefits (in addition to flood control) may influence greater public and political acceptance. Thus, the paper uses a multifunctional design approach using the urban open space system and combining the blue-green and gray infrastructure. A hydrodynamic model was used to support flood mapping. This approach also increases the land value and the environmental quality of the urban spaces. Two quantitative aspects support this evaluation. The first one represents the land value increase as a positive effect, while the second one assesses the environmental quality of the urban space using the Environmental Quality Assessment Index (EQAI). The results obtained from the urban and environmental evaluation proved that blue and green corridors could promote multiple co-benefits for consolidated urban areas. The increased environmental quality and land value were only possible due to the combined use of BGI and gray infrastructure since BGI can add benefits that the gray infrastructure is not capable of providing.

将蓝绿基础设施作为一种多功能方法,用于社会环境脆弱的流域
本文研究了如何使蓝绿色基础设施的实施更具吸引力,以解决人口密集、缺乏防洪和环境质量保护基础设施的流域中的城市问题。考虑到在发展中国家实施多功能解决方案的障碍,衡量其共同利益(除防洪外)可能会影响公众和政治的接受程度。因此,本文采用了一种多功能的设计方法,利用城市开放空间系统,将蓝绿色和灰色基础设施相结合。流体动力学模型用于支持洪水绘图。这种方法还提高了土地价值和城市空间的环境质量。有两个数量方面支持这一评价。第一种方法将土地价值的增加视为一种积极影响,而第二种方法则使用环境质量评估指数(EQAI)来评估城市空间的环境质量。城市和环境评价结果表明,蓝色和绿色走廊可以促进城市综合区的多重共同利益。只有BGI和灰色基础设施的结合使用才有可能提高环境质量和土地价值,因为BGI可以增加灰色基础设施无法提供的好处。
