提出一种采用植被物候校正的指数VPAUI,并将其应用于中部城市群的建设用地扩张监测.首先利用植被物候参数对NTL数据进行去饱和处理并构建VPAUI,然后建立建设用地丰度和VPAUI的线性关系模型.以中部城市群的3个省会城市武汉、长沙和南昌为研究区域,利用VAPUI指数进行长时序的监测.结果表明,利用VPAUI提取的建设用地丰度能更好地解决夜间灯光强度饱和现象,能有效辨识出城市扩张的热点区域.在2001年-2013年间,武汉和长沙新增建设用地面积相当,扩张速度由慢变快,发展迅速,南昌建设用地扩张面积偏少,扩张速度由快变慢,发展滞后于武汉和长沙.

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 pa rameters. 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...
