An update of the vegetation classification in China

The vegetation classification in China was updated by referring to recent advances for vegetation classification worldwide and on the basis of our former paper Recognition and Proposal on the Vegetation Classification System of China (hereafter, "Recognition and Proposal"). In this revision, the criteria for vegetation classification were discussed and unified, and a quantified standard for high, medium, and low level units in a new hierarchical classification scheme was supplemented. Compared with the old classification scheme in "Recognition and Proposal", the units at the level of vegetation type were substantially changed. Finally, in order to improve mutual communication among international peers, a comparison was carried out between the new revised scheme and each of International Classification and Mapping of Vegetation of UNESCO, The National Vegetation Classification Standard of United States, and The Braun-Blanquet Classification Scheme.
