本文通过Modis 1B数据计算了2009～2013年滇中地区内NDVI值，并用最大值合成法（MVC）获得了NDVI月时间序列数据，利用相关性分析和差值分析定量描述了农田、森林、灌丛和草地4种绿色覆被NDVI年内变化曲线在年际时间尺度上的协同性和差异性。%This paper calculates the NDVI values within the 2009-2013 in the central Yunnan Province by Modis 1 B data, and NDVI monthly time series data is obtained with maximum synthesis (MVC). By using correlation and difference analysis, the synergies and differences of NDVI curve during the year on interannual time scales of the 4 types of green cover:farmland, forest, scrub and grassland are described quantitatively.
