地球植物区系分区提纲

An Outline on the Regionalisation of the Global Flora

全球植物区系区划，或植物地理分区，从甘世纪以来有过许多著名的、有影响的区划和著作．它们把中国中部及北部的植物归入泛北极区，而把华南的植物归于古热带区，这种区划是和中国植物区系起源的实际背道而驰的．非洲的热带区系和亚洲的热带区系各有本身的起源和发展道路，把二者归并为古热带植物区，是很不协调的．本文把全球植物区系划分为：劳亚植物界，华夏植物界、澳大利亚植物界、非洲植物界、南美植物界、南极植物界、热带红树植物界．

All the publications on the regionalisation of the world wide floras werecommonly based on the present condition of distribution and neglected the histosicalorigination and develpment of the flora,As to the primitive and integrated Chineseflora,it seems that they neglected the historical development of the Cathaydian flora,and included the northern China into the Pan-Arctic flora,and southern flora to thePalaeotropic,it is obviously broken the integration of the Cathaysian flora. Moreover,the African flora combined with the Asian tropic as Palaeotropical flora is inadequate,since the first was originated from Gongwana,and the latter was from Cathaysia.(Biology department, Zhongshan University, Guangzhou 510275)In this paper,according to the origination of the global flora,seven floral kingdomswere proposed. 1.Laurasia kingdom. 3 regions,34 provinces. 2.Cathaysia Kingdom. 3 regions,33 provinces. 3.Australia kingdon. 4 regions,7 provinces. 4.Africa kingdom. 2 regions,25 provinces. 5.South America Kingdom,4 regions,12 provinces. 6.Antarctic kingdom. 4 regions,15 provinces. 7.ropical mangroves kingdom. 5 regions,16 provinces.
