摘　　要：利用2009—2019年肇庆市郊自动站逐日逐时的气温观测资料计算近10年肇庆热岛强度,统计分析了肇庆城市热岛效应的变化特征。研究表明:肇庆城市热岛强度有明显日、月和季节变化特征,一般日间出现"冷岛"而夜间出现"热岛",春季最小秋季最大,10月热岛强度最大,4月热岛强度最小;肇庆热岛效应常年稳定存在,热岛强度呈缓慢增加的趋势;近10年平均热岛强度为0.61℃。Using the day-to-day hourly temperature observations from the automatic weather stations in suburban Zhaoqing from 2009 to 2019, this work computes the intensity of heat island effect over this period of time and statistically analyzes its variation characteristics. The result is shown as follows. Being the smallest in April(spring) and largest in October(autumn), the intensity of the urban heat island effect varied significantly on the daily, monthly and seasonal scales, usually with a "cold island" appearing during the day and a "hot island" at night. In Zhaoqing, the heat island effect was present all year round, with the intensity gradually increasing at an average rate of 0.61 ℃ over the 10 years.
