基于LCZ理论的上海传统水乡村镇气温分布特征——以上海新场古镇风貌保护区为例

Temperature Distribution Characteristics of Traditional Waterside Townships in Shanghai Based on LCZ Theory——Taking the Landscape Conservative Area of Xinchang Ancient Township,Shanghai as an Example

以局地气候分区理论为依据,采用现场气温观测方式,对上海新场古镇温度分布特征进行研究,探究传统聚落形态与温度分布的影响关系。结果表明:水体在日间对周边热环境降温作用明显,但该处在夜间容易形成热岛效应;树荫、构筑物的遮挡作用具有明显的降温效果;实测结果表明传统滨水步道、冷巷、廊棚等公共空间对夏季过热环境的缓解具有积极作用。研究结果可为城市微型空间热环境的调节优化,创造低碳舒适的人居活动环境提供参考。

On the basis of the theory of local climate zoning and adopting on-site temperature observation, the temperature distribution characteristics of Xinchang Ancient Township in Shanghai were researched, and the influence relationship between traditional settlement form and temperature distribution was explored. The result shows that: the water body gets the surrounding thermal environment significantly cooled during daytime, but it is easy to form a heat island effect at night;the shade of trees and structures have obvious cooling effects;the actual measurement results show that traditional waterside walks, cold lanes and corridors have positive effect on alleviating the overheated environment in summer. The research result can provide reference for adjusting and optimizing the thermal environment in urban micro-space and creating low-carbon and comfortable living environment.
