武汉市蓝绿基础设施调节和支持服务价值评估研究

城市蓝绿基础设施为城市提供着多种类型的调节和支持服务。以武汉市域范围内的蓝绿基础设施为研究对象，以遥感影像和相关研究资料为基础，综合多种类型的生态系统服务评估方法，计算了1987—2015年间，武汉市中心建成区，都市发展区和城市远郊区3个研究区域水文调节、水质净化、固碳释氧、空气净化、噪声降低、气候调节和生物多样性保护7项调节和支持服务的量化收益和货币价值。最后对蓝绿基础设施的调节和支持服务在价值总量、单位效能、供需平衡、空间分布和时间变化等方面的规律进行了分析。

Evaluation of Green and Blue Infrastructure Regulating and Supporting Services in Wuhan

Urban green and blue infrastructure provide multiple regulating and supporting services for the city. This research focuses on green and blue infrastructure in Wuhan city area. Based on the remote sensing images and other related materials, this research evaluates the economic value of 7 regulating and supporting services (runoff mitigation, water purification, carbon sequestration and oxygen releasing, air purification, noise reduction, climate regulation and biodiversity conservation) in the urban central district, urban developing district and urban suburb district from 1987 to 2015 by using multiple evaluation methods. Finally, this research summarizes the pattern of regulating and supporting services provided by green and blue infrastructure in 4 aspects: accumulated value, performance per unit area, supply-demand balance, spatial distribution and time variation.
