- 摘要：
- Urban villages are one of the most dominating urban residential patterns in China, which possess diverse morphological characteristics. These urban enclaves not only offer adequate affordable housing for migrant workers, but also provide insights for establishing climate-adaptive urban neighbourhoods. Through choosing Hubei Village (Shenzhen) as the case-study area, and focusing on density factors, the research aims to explore the correlation between urban density and the characteristics of outdoor thermal environment in urban villages. In this paper, a total of 28 outdoor spaces with different morphologies in Hubei were analysed and compared. Air temperature, relative humidity, air velocity, and globe temperature were monitored for three days during typical summertime. The research examines urban heat island intensity (UHII) and universal thermal climate index (UTCI) to present the thermal environment in urban villages. The implications of the results on 1) the most critical density factors that influence outdoor thermal environment, and 2) strategies learned from diverse environmental patterns in Hubei for early urban design and later urban rehabilitation. The results demonstrate that sky view factor (SVF) plays a leading role in influencing UHII and UTCI, and urban villages with high density mid-rise pattern have better outdoor thermal environment than modern high-rise building blocks.
