乡村住区下垫面表面温度实测及影响因素分析——基于冬季红外热成像航拍实验数据

Measurement of the Underlying Surface Temperature of Rural Settlements and Analysis of Influencing Factors—Based on Winter Experiment Data With Thermal Imaging Aerial Photography

住区下垫面对室外热环境有重要影响,关于乡村住区下垫面研究存在缺失。文章选取上海市闵行区丰收村的一处住区组团作为实验场地,利用热成像无人机作采集数据,获取冬季典型日白天时段下垫面的表面温度。研究结果表明:太阳辐射、下垫面的材质、色彩等要素对于下垫面得热情况具有显著影响;硬质下垫面的温度普遍高于自然下垫面;遮挡可以减少气温波动幅度。文章揭示出乡村住区下垫面得热差异及内在机制,可为乡村室外环境设计提供科学依据。

The underlying surface of the residential area has an important impact on the outdoor thermal environment.Existing related researches are mainly concentrated in urban areas,while less attention is paid on the underlying surface of rural settlements.Reasonable design of the underlying surface is an important aspect of improving the rural living environment,and revealing the heat gain of different underlying surfaces is the basis of the above work.This paper selected a residential cluster in Fengshou Village,Minhang District,Shanghai as the experimental site,and used thermal imaging UAV to collect data to obtain the surface temperature of a representative underlying surface during a typical winter day.This paper reveals the difference in heat gain and the internal mechanism of the underlying surface temperature of rural residential areas through the actual measurement and analysis of the underlying surface temperature of rural residential areas,which can provide a scientific basis for the planning and design of rural outdoor underlying surfaces.
