摘要: 本次研究利用MODIS植被指数产品以及DMSP/OLS遥感影像数据，通过重新投影、影像裁剪、栅格计算等方法，反映出贵州省2000~2009十年间年际和空间的夜间灯光和NDVI动态变化。结果表明：2000~2009十年里，贵州省的NDVI呈现出升高趋势，高植被覆盖度区域面积明显增加；灯光强度持续增强，且有从以城市为中心向周边城郊扩张的趋势；而且NDVI与夜间灯光强度呈反相对关系。
Abstract: This research is aimed at reflecting the lights and NDVI dynamic changes in the inter annual and spatial night of Guizhou during the 2000-2009, by using the MODIS vegetation index and the re-mote sensing images from DMSP/OLS, through some methods, like reprojection, image clipping, grid computing and some other methods. The results show that during 2000 to 2009—the ten years, the NDVI of Guizhou Province and show an upward trend, high vegetation coverage area increased significantly; the light intensity continued to improve, with the trend of expanding from the city which as a center to the surrounding suburban; and the NDVI and nighttime light intensity is an inverse correlation relationship.
