中国种子植物区系定量化研究——Ⅰ区域性种子植物区系研究实用程序工作原理(QX—系列程序)

In the present paper, practical programs for the quantitative study of the seed plant flora of any a given region of China are worked out according to the areal-type classification of seed plants of China proposed by Professor C. Y. Wu. By use of these programs, the statistical data of the seed plant areal-types, composition of families, genera and species of any a given seed plant flora as well as the Jaccard's similarity coefficient of genera of this flora with another one can be readily and exactly obtained.
