摘　　要：Based on 60 years of climate data from three national-level stations in Ziyang City,the characteristics of interdecadal variations of temperature,humidity,precipitation and sunshine that were closely related to heat island effect were analyzed.The data of township regional stations were used for comparison.The results show that the heat island effect value of Ziyang was between 0.3 and 4.3℃.It was the highest in 2015,up to 4.3℃;the minimum 0.3℃ appeared in 2011.The average heat island strength in the past 10 years was 1.2℃,and the average heating rate was 0.12℃/a.Among the four seasons,the highest value of heat island effect was 3.2℃ in summer,while the lowest value was 1.2℃ in winter.The order of heat island value in various seasons is as follows:summer>autumn>spring>winter.
