Abstract: Based on meteorological observation data—including temperature, wind speed, shallow soil moisture, and CO₂ concentration—collected from the Guangdong G8208 urban station and a suburban orange park on high-temperature days over the past five years, as well as urban traffic flow data, this study performs a classification calculation incorporating the urban green space vegetation coverage rate. Consequently, an equation for temperature variation in the urban microclimate is constructed, which is adjustable under the influence of this multi-factor set.
