| Abstract: |
| Objective To study the influence of urban heat island effect on the ambient temperature. Methods Temperature data from 1960 to 2015 from the small and medium-sized cities and rural (CK) reference climate stations in central and western Liaoning was used to have quantitative study on the interannual variation characteristics of temperature in small and medium-sized cities and its urban heat island warming effect with the statistical comparative analysis method. Results In the late 1980s, the urban air temperature had obvious "abrupt changes" in climate, and the "abrupt changes" in air temperature mainly came from the influence of urbanization heat island. Compared with the rural temperature change, the urban heat island increased the annual average temperature by 0.65 ℃, and the urban heat island effect was 147.7%. Urban heat island increased the average temperature in spring, summer, autumn and winter by 0.41, 0.41, 0.72 and 0.80 ℃ respectively. The urban heat island effect in four seasons was 59.4%, 256.3%, 450.0% and 106.7% respectively. In the annual change, the maximum warming value of urban heat island effect was in January, and the contribution to heat island warming was the greatest from September to March of the following year. Conclusion The meteorological monitoring stations are located in cities. The temperature data tested are affected by the urban heat island phenomenon, which masks the actual situation of natural climate change, resulting in high temperature detection results, thus affecting the application of temperature indicators in agriculture and agricultural scientific research, civil construction and bridge and culvert construction. |
