jailcd2024025: Empirical Study on the Impact of High-Density Urban Form on Temperature

Abstract

In recent years, climate change has led to frequent urban disaster events, and urban heat islands have become the focus of research. However, most of the current papers focus on simulation, but there is a lack of empirical research on the thermal environment of high-density cities. This article takes Macao as the research object to explore the impact and relationship of urban morphology on the urban thermal environment. Macau, as a
typical representative of high-density cities, gathers a large number of tourists and residents. This article analyzes the current status of the thermal environment through data from meteorological monitoring stations. At the same time, urban morphological factors such as building density, road length and green space density were extracted to analyze the impact of urban morphology on the thermal environment, and regression analysis was used to establish the relationship between urban morphological factors and temperature. The regression
results show that the effect of road length on temperature is significantly related. The research reveals the importance of urban transportation planning strategies and urban form guidance in improving urban temperature, enriches urban theory from an empirical level, and provides reference solutions for urban design.
