| 摘 要： | 相似性系数的正确理解和运用。对植物区系地理学中的植物区系分区，过渡区的植物区系地理属性及植物区系起源演化都具有重要的理论意义，本文通过对相似性系数，种相似性系数，属相似性系数和科相似性系数等术语的阐述，提出了“区系相性系数（ｃｏｅｆｆｉｃｉｅｎｔｏｆｓｉｍｉｌａｒｉｔｙｏｆｆｌｏｒａ）”概念，简要介绍了属或种（或科）相似性系数在应用中存在的问题和解决的办法。并建议：在植物区系地理化比较研究中，采取

| Abstract: | It is most imporiant in Floristic Geography for diving floristic region, geographical features of transitional floristic region and evolution of flora that correcting and using the coefficient of sidrilarity. The author have cornmented the formulas and definitions of different coefficient in flotistic research,give the definition of the Coefficient of Similarity of Flora, brief introduce exit problems and solved the way in application of coefficient of similarity to floristic geography in the paper. The author also suggests adopting a same and scientific mathematical formula in the comparison study of floristicgeography in the future. |
