| 鉴于城市降温对人类健康和户外城市空间生活质量的重要性,如今对城市降温的需求日益迫切。但基于室外热舒适度的改善和城市分区方法开发仍具有挑战性。城市街区形态对室外热环境有重要影响,局地气候分区的城市热环境分析可以帮助更好地理解和改善城市热舒适度。本文选取干旱气候区乌鲁木齐具有代表性的区域作为研究区,借助实地监测、ArcGIS地理空间可视化、相关性分析,揭示城市街区形态对室外热舒适的影响。结果表明：(1)温度和湿度对室外热舒适有着显著的影响,温度对热舒适的影响大于湿度；(2)城市形态对热舒适的影响错综复杂,土地利用差异会对热舒适产生不同的影响,在40米缓冲区范围城市形态对局部热舒适度相关性更显著。 |

| Abstract: |
| Given the importance of urban cooling to human health and the quality of life in outdoor urban spaces, the need for urban cooling is becoming increasingly urgent. However, the improvement of outdoor thermal comfort and the development of urban zoning methods are still challenging. The shape of urban blocks has an important impact on the outdoor thermal environment, and the analysis of urban thermal environment in local climate zoning can help to better understand and improve urban thermal comfort. In this paper, the representative areas of Urumqi in the arid climate region were selected as the study area, and the influence of urban block morphology on outdoor thermal comfort was revealed with the help of field monitoring, ArcGIS geospatial visualization and correlation analysis. The results show that: (1) Temperature and humidity have significant effects on outdoor thermal comfort, and the influence of temperature on thermal comfort is greater than that of humidity; (2) The influence of urban form on thermal comfort is complex, and land use differences will have different effects on thermal comfort, and the correlation between urban form and local thermal comfort is more significant in the 40-meter buffer zone. |
