Effects of Urban Morphology and Anthropogenic Heat Emissions on Summer Micro-climate in Xi’an, China
Many studies have proved that urban morphology (UM) and anthropogenic heat emission (AHE) have significant effects on urban microclimate. However, existing research has mostly focused the effects from UM on microclimate or the effects of AHE on microclimate respectively. Therefore, this study quantifies the relationship among UM, AHE and microclimate, using correlation and regression analysis based on field measurement data of air temperature (AT) in summer in 5 typical urban blocks of Xi'an, a high-density city in western China. Results show that AHE explains more than 70% of the hourly AT variation. In addition, the greening cover ratio (GCR) is the strongest index, which helps to cool down the AT and reduces the AHE. 10% increase in GCR decreases the average AT by 0.43 °C and AHE by 118 W/m2. This study established a comprehensive model for the impact of UM and AHE on microclimate and provides guidance for developing cooling strategies in high-density urban areas.
