| 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:NPP-VIIRS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。

| Abstract: | 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 NPP-VIIRS 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. |
