ArcGIS processing of remote sensed and investigated data of Guizhou forest resources in 2000 gives rise to forest resource distribution map, forest age class structure, and the distribution map of forest canopy. Analysis of these data shows that: (1) though there are multiple types of forest resources, forest coverage is low (only 25.27%, excluding sparse woodland, shrub and underage-forest);(2) the geographical distribution of forests is quite uneven, mainly in the southeast of the province and in Zunyi prefecture; (3) the zonal evergreen broad-leaved forests have been seriously destroyed, and the forest has obvious secondary features, with coniferous forest and shrubbery accounting for the greatest proportion of Guizhou forest; (4) the area of timber-forest is much larger than that of shelter-forest and economic forest; (5) young-and-middle age forests account for greater proportion than near-and-over matured forest; and (6) the forest of Guizhou is not enough to effectively protect the environment of karst mountain areas of the province.
