QUANTITATIVE STUDIES ON THE SEED PLANT FLORA OF CHINAI. COMPUTER PROGRAMS FOR THE STATISTICALANALYSIS OF THE SEED PLANT FLORA

摘要:

本文根据吴征镒教授对中国种子植物属分市区类型研究结果,研制出定量化研究区域性种子植物区系的电子计算机程序,应用本程序可完成某区系的分布区类型统计分析,科属组成分析和与其它地区以共有属关系构建的相似性系数的谁知盘中计算,同时可大量节省研究人员的劳动强度和时间,对提高研究水平有一定的效果。

Abstract:

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.

Key words:Seed plant flora; Areal-type classification; QX program
