中文摘要：
以洛河流域为研究区域，以反照率为研究对象，根据同时相的ETM＋与MODIS数据探讨了地表参数的一致性问题．在对ETM＋影像进行地形与大气校正的基础上，利用窄波段反射率组合方法获取了研究区的地表反照率，通过ETM＋反演的反照率与MODIS二向反射函数（BRDF）反演的反照率产品的对比分析得出了两者间的关系．
英文摘要：
In a case study of Luohe River Basin, the consistency between the land surface parameters obtained from the ETM ＋ and MODIS data of the same phase was discussed. The ETM ＋ data was corrected according to the topographical and atmospheric information, and the land surface albedo of the studied area was obtained by the combination of reflectances of the narrow bands. The land surface albedo obtained from the ETM ＋ data was compared with that obtained from the inversion of MODIS BRDF （bidirectional reflectance distribution function） based on the land surface classification map, and a linear relationship between them was obtained.
