重庆市华岩新城区夏季热岛效应研究

STUDY ON HEAT ISLAND EFFECT OF HUAYAN NEW CITY IN CHONGQING IN SUMMER

用流动观测法分别于夏季的昼间和夜间测试重庆市华岩新城区范围内观测线路上各点的空气温度值,对测试数据进行同时性订正后,绘制出华岩新城区等温线图。分析结果后发现:华岩新城区夏季昼间和夜间的热岛中心均位于北部道路侧的工业区,且夜间南部的一个农村出现了热岛副中心。新城区的水体对夏季昼间的热环境降温效果不明显,而在夜间由于水体将昼间的蓄热量散失,反而加剧了夜间的热岛效应。结合郊区温度测试数据,计算出华岩新城区夏季夜间和昼间的热岛强度分别为1.3～1.4℃和0.4～0.8℃。此外,对用于华岩新城区室外热环境信息化管理的《城镇热岛信息管理系统——华岩》(UHIIMS-HY)软件作了简要介绍。

Temperatures of each point on the observation route were gathered in Huayan new city during the daytime and nighttime in summer by moving observations. Then, the isotherms for Huayan new city were presented after correcting data to be synchronous. The results showed that the heat island center of Huayan new city in both daytime and nighttime in summer locates in the northern industrial district by roadside, and a sub-center of urban heat island appears in a village in the southern part. The water body in the new city has an unapparent effect on lowering the temperature during daytime in summer, however, it aggravates the heat island effect at night as the water body releases the heat stored during the daytime. Additionally, with the survey data in suburb, the urban heat island intensity in ordinary summer nighttime and daytime are about I. 3-1.4℃ and 0.4-0.8℃, respectively. Furthermore, the Urban Heat Island Information Management System--Huayan （UHIIMS-HY） software was briefly introduced, which was used for the information management of outdoor thermal environment in Huavan new airy_
