摘要
通过对合肥城市热岛效应的研究 ,发现合肥全年存在热岛效应 ,热岛强度 (ΔTu-r)年变化表现为 6、7月份最强 ,1 2、1月份最弱 ;ΔTu-r日变化出现两个峰值 ,与市中心人流、车流高峰一致 ;合肥城市热岛中心位置随季节变化 ,合肥热岛强度(ΔTu-r)随人口增长而逐年增强 ,1 998年最高值达 5.9℃。根据灰色预测 ,到 2 1世纪初随着人口增长ΔTu-r可能达 9.2℃ ;绿化效应的研究为城市规划。
In this paper, the effect of the urban heat island of Hefei was studied. The results showed that the effect appeared all over the year, and the strongest was in June and July, the weakest was in December and January. The two peaks of diurnal variation of the effect consisted with the peak flow of the people and vehicles. The center of the urban heat island changed with the seasons and Δ T u-r increased with population with the highest reaching 5.9 ℃ in 1998. According to the gray forecast method, the intensity of the urban heat island would be 9.2℃ with the increasing of the population at the beginning of the 21th century. This study of greening effect provides a scientific basis for the city planning and greening construction.
