| 摘要 | Based on the observation data of meteorological observation stations in Jining City during 1970-2024, MK mutation test and principal component analysis (PCA) were used to study the evolution characteristics of urban heat island intensity (UHII) and the contribution rate of various influencing factors in Jining City over the past 55 years. The results show that from 1970 to 2024, the UHII in Jining City generally rose at a rate of 0.1 ℃/10 a. On the interannual scale, the correlation between temperature and UHII was most significantly positive. On the seasonal scale, there was a strong negative correlation between wind speed and UHII. PCA reveals that temperature had a significant positive impact on the increase of UHII in Jining City. |
