Abstract
Urban parks have been considered as an effective measure to mitigate the urban heat island (UHI) effects. Many studies have investigated the impacts of shape, size and interior components on the cold island effect (CIE) of parks, while little attention has been given to the impact of neighboring buildings. Thus, taking twenty-two parks in Beijing as samples, this study investigated the impacts of the neighboring building on the CIE of central parks. The results showed that the average land surface temperature (LST) of parks are 30.98 °C in summer and −1.10 °C in winter. Parks have a strong CIE in summer, and average cold island footprint (CIF) and LST difference are 0.15 km2 and 2.01 °C higher than that in winter. The components of the building in the CIF of parks are dominated by middle-rise building (MRB), followed by low-rise building (LRB), and high-rise building (HRB) is the least dominant. The percentage of landscape (PLAND) and landscape shape index (LSI) of MRB, and perimeter area fractal dimension (PAFRAC) of LRB are significantly related to CIF in summer and winter. This study could extend scientific understanding of the impacts of neighboring buildings on the CIE of central parks, and could guide urban planners in mitigating the UHI effects through the rational allocation of buildings.

Urbanization transforms the natural surface into impervious surface, while a high population in urban area accelerates this transformation [1,2,3]
This study investigated the impacts of neighboring building on the cold island effect (CIE) of central parks based on Landsat 8 OLI images, GF2 images, and building dataset
This study could extend scientific understanding of degree to which CIE of central parks are affected by neighboring buildings, and could provide guidance to urban planners on how to mitigate the urban heat island (UHI) effects through the rational allocation of buildings
Summary
Urbanization transforms the natural surface into impervious surface, while a high population in urban area accelerates this transformation [1,2,3]. This transformation was considered as one of the major causes for the phenomenon of urban heat island (UHI) [4,5]. The UHI refers to urban temperatures being higher than those in rural areas [6]. This negatively affects the quality and health of inhabitants [7,8]. Most of the existing research emphasized that built-up areas could increase the UHI effects, while water bodies and vegetation lands decrease it [1,17,19,20]
