Abstract: Authors suggest to define "East Asian forest subkingdom" and "Hengduang -Himalayan M ts.forest subkingdom" instead of "Sino -Japan forest subkingdom" and "Sino -Himalayan forest subkkingdom" for the regionalization of Chinese Flora, because both "Sino" do not be used for the representations of geography of whole country. Otherwise, it would be equitable to introduce the "Sino -C. Asia steppe & desert subkingdom", "Sino -Pamir Plateau subkingdom" and "Sino -S. Asia tropical forest & Savanna subkingdom" instead of "Asiatic desert subkingdom", "Eurasia steppe subkingdom",、"Qinghai -Xizang plateau subkingdom" and "Malaysian subkingdom".Authors also suggest to divide the subtropical zone in China, into cool, central and warm subtropical subzones for the climatic and plant vegetative zones instead of North, Central and South subtropical subzones, because it is easy to be confused by the subtropical zones in North, "Central" or in South Hemispheres and it is also named the cold temperate, temperate and warm temperate subzones instead of North, Central &South temperate subzones.All of nomenclatures are equitable to be used in both Hemispheres.
