The detail of FCM16. (a,b) are the map and the local statistical accuracy of the FCM16 respectively. (c–g) represent the high-resolution satellite maps and the FCM16 for the five sites (c–f) in sub-image (a) respectively. Site (c) is located in the densely forested distribution area in south China; site (d) is located in the Sichuan basin, where forests are small and interspersed with farmland; site (e) is located in the transition area of the Loess Plateau, where vast ecological protection forests have been planted; the site (f) locates in the Northeast, where a large number of planted forests are distributed; and the site (g) locates in the Altai Mountains, where the forests are relatively homogeneous and dominated by coniferous forests.
