Abstract：A Vegetation Phenology Adjust Urban Index (VPAUI) was proposed and applied to the monitoring of the expansion of built-up areas in Central China. Firstly， VPAUI was constructed by desaturating the NTL data using vegetation phonological parameters. Secondly， the linear relationship model between built-up fraction and VPAUI was established. Finally， the long-term time-series monitoring was carried out using the VAPUI index in provincial capitals of Wuhan， Changsha and Nanchang in the Central China. The results show that built-up fraction based on VPAUI is able to better solve the intensity saturation problem in nighttime light， and effectively identify the hot spot of urban expansion.
