摘　　要：基于GIS空间分析和数学统计方法,利用TERRA、AQUA和NPP-VIIRS卫星数据反演了西藏日土县植被归一化指数(Normalized Difference Vegetation Index,NDVI),并对不同卫星传感器反演结果的一致性进行了检验评估。结果表明:NPPVIIRS卫星反演的NDVI值略大于TERRA和AQUA的反演值,其估算结果与MODIS卫星估算值存在较好的相关性。NPP-VIIRS卫星可以用于西藏高原植被长势监测工作,为西藏生态文明高地建设提供更加丰富的遥感数据支撑。Based on GIS spatial analysis and mathematical statistical methods,the normalized difference vegetation index(NDVI)of Ritu County in Tibet was retrieved by using TERRA,AQUA and NPP-VIIRS satellite data,and the NDVI retrieval results of different satellite sensors were discussed.The results show that the NDVI value retrieved by the NPP-VIIRS satellite was slightly larger than that of TERRA and AQUA,and the estimated result had a good correlation with the estimated value of the MODIS satellite.Therefore,the NPPVIIRS satellite can be used in the vegetation growth monitoring of the Tibetan Plateau,and provide richer remote sensing data for the construction of ecological civilization of Tibet.
