Cooling Effect of Green Space and Water on Urban Heat Island and the Perception of Residents: A Case Study of Xi'an City.

ABSTRACT: The urban heat island (UHI) is a typical environmental problem that affects people's health and restricts urban development. Understanding the cooling effect of ecological landscapes and residents' perceptions of the cooling effect can help guide urban planning and mitigate environmental risk. This study analyzed the spatiotemporal evolution of UHI in the central area of Xi'an City in 1999, 2006, 2014, and 2019, and compared the cooling effect of green space and water among 13 urban parks in 2019. Furthermore, we investigated the constraining effect of landscape patterns on UHI and residents' perceptions. Our results show that the area of moderate temperature region increased significantly in the past 20 years, and the UHI of old urban areas has been reduced. The UHI hot spots generally mi
