摘要: Abstract Urbanization has increasingly become a prevailing issue confronting scientists worldwide due to its effects on temperature and environment. This study explored of decadal urbanization local from Landsat data in Cantho city, Vietnam 1996 2016. The mapping results built-up areas achieved the random forests (RFs) indicated overall accuracies Kappa coefficients higher than 89.5% 0.79. city had been drastically expanded with increasing 1,274.0 ha 2,932.7 ha 2006, 3,428.8 ha 2016, respectively. by transforming opened lands artificial surfaces led temperature. retrieved revealed obtained for range 25.7–37.1 °C, while values 2006 2016 falling between 26.3–37.3 °C 24.1–40.2 °C, average urban increased 0.8 °C 31.7 °C 32.5 °C Considering 32 °C as an uncomfortably hot threshold that may affect human health environment, only 637.7 ha was observed 1996, those 1,131.9 ha 2,155.4 ha,
