This paper aims to disclose the impact of urban high-speed rail (HSR) construction on the urban heat island (UHI) effect and predict the UHI effect in future. For this purpose, the radiation transmission method was adopted to investigate the UHI effect in south-eastern China’s Nanchang city, and forecasted the UHI effect from 2018 to 2025 in Nanchang via longitudinal greyscale simulation. The research results show that: the surface temperature is closely related to the urban HSR construction; the maximum surface temperature increases with the built-up area of the HSR; different factors have different effects on the UHI effect, among which population is the leading influencing factor; the mean temperature in 2018~2025 indicates the HSR construction in Nanchang has a severe HSR effect. The research finding shed new light on the studies of UHI effect and its influencing factors.
