摘要
城市热岛是城市地区温度高于周边农村地区的一种现象,也是城市气候研究中最为关注的热点之一。目前国内外学者对城市热岛问题进行了广泛研究,但研究对象主要集中在大城市或特大城市,对于中小城市研究偏少,基于此,以泰安市为例,对中等城市热岛时空演变及其影响因素进行分析。冠层热岛具有显著的日变化和季节变化特征,其强度与城市发展、下垫面粗糙度息息相关。主要采用山东省泰安市2016—2020年5年逐日地面气象观测资料,选取代表城市的5个站点(财源、东湖、上高、泰安二中、泰山区),以及代表郊区的6个站点(夏张、满庄、房村、马庄、良庄、颜谢坝)的平均气温和降水资料,并采用统计方法研究了泰安城市热岛年际变化特征及其与降水的关系,发现城市热岛效应强度与降水的负相关关系。
Urban heat island was a phenomenon that the temperature in urban areas was higher than that in surrounding rural areas. It was also one of the most concerned topics in urban climate research.At present, scholars at home and abroad had conducted extensive research on Urban Heat Island, but the research objects were mainly concentrated in large cities or mega cities, and there was little research on small and medium-sized cities. Based on this, this paper takes Tai’an city as an example to analyze the temporal and spatial evolution of heat island and its influencing factors in medium-sized cities. Canopy heat island had significant diurnal and seasonal variation characteristics, and its intensity was closely related to urban development and underlying surface roughness. Based on the daily surface meteorological observation data of Tai’an city in Shandong province from 2016 to 2020, the average temperature and precipitation data of 5 stations representing the city(Caiyuan, East Lake, Shanggao,Tai’an No. 2 middle school and Taishan District) and 6 stations representing the suburbs(Xiazhang, manzhuang, Fangcun,Mazhuang, Liangzhuang and yanxieba)were selected, and the interannual variation characteristics of urban heat island in Tai’an and its relationship with precipitation were studied by statistical methods, It was found that the intensity of urban heat island effect was negatively correlated with precipitation.
