基于MODIS的干旱区植被覆盖度反演及植被指数优选OA北大核心CSCDCSTPCD
Remote Sensing Inversion of Vegetation Coverage and Optimization of Vegetation Index Based on MODIS Data in Arid Area
为进一步掌握塔里木河下游输水后的生态恢复程度,以输水河畔的植被覆盖度为研究对象,采用MODIS数据构建研究区多种植被指数;结合现场实测植被覆盖度,给出离散坐标下实测植被覆盖度与各种植被指数间的二维散点图,据此得出二者相关方程,反演区域植被覆盖度.结果表明,基于MODIS数据构建的NDVI、MSAVI、SAVI和EVI等植被指数均与植被覆盖度有较好的相关关系,采用这些植被指数反演植被覆盖度的精度由高到低依次为NDVI、EVI、MSAVI及SAVI.…查看全部>>
To further understand the ecologic restoration level after water supplying, the authors studied vegetation coverage (Fv)in the water supply area of the lower reaches of the Tarim River. Correlation equation and twodimensional scatter plot between Fy and vegetation index (Ⅵ) could be obtained based on MODIS data by constructing a variety of Vis in combination with measured Fvs, and the value of Fv could be figured out based on the relevant equation. The resul…查看全部>>
