These two studies in 2021 and 2019 show that, in urban areas, the start-of-season usually occur earlier, and end-of-season latter, overall enhancing the length of the growing season.
There are, however, exceptions to this rule. The responses of start and end of season depend on the background climate of the urban area (latitude, spring day- and nighttime temperatures). The northern cities have greater urban-rural distinction than the southern cities.
The corresponding authors to these studies were Shuqing Zhao from Peking University, and Xinchang Zhang from Guangzhou University & Qinchuang Xin from Chinese Academy of Sciences and Sun-Yat Sen University.
