- Abstract:
-
Based on the LCCS, this article proposed a method for assessing the relative consistency of large scale land cover products, hereafter GLOBCOVER and MODIS COLLECTION5 were used as validate data to prove the method. The results show that the percentage of higher affinity value is lower because of the difference of category threshold, and concentrated in northern China, Sichuan basin, Taiwan Province, northwest desert and eastern Himalayas. The zonal statistics demonstrated the significant differences, for example, in Northeast, the percentage of high value and low value is almost identical, the value was between 0.5~0.7, occupying the 35%; in northern China, the high value showed an apparent advantage, there was about 63% of area great than 0.9; in southeast region, the region of high value is more than low value, but in Tibet alpine, the tend is adverse compared with southeast region; Sichuan basin has the similar vegetation composition, so the affinity value distribution is analogous with northern China; the affinity value percentage showed a uniform distribution, there was no predominant value interval.
