      niche similarity
    However, communities that are located within tens of kilometers of one another appear to show a large degree of order, probably due to underlying principles of niche similarity.
          


    In this paper we discuss the relations between several coefficients of community similarity in plant ecology, which are suggested sucessively by Jaccard(1912), Sφrensen (1948), etc, and analyse their reasonabilities, for instance, we show that the coefficient defined by Motyka is the same as Renkonen's(1938) coefficient of niche similarity and that the coefficient originated from Motyka's rule suggested by Spatz (1970) is irreasonable. Finally, we point out that it is suitable to measure the community...

Finally, we point out that it is suitable to measure the community similarity by use of the coefficient of niche similarity defined by Wang and Yang (1982).

    本文讨论了植物生态学中由Jaccard(1912)和Sφrensen(1948)等人相继提出的关于群落的相似系数之间的关系,并分析了它们的合理性,例如,我们指出,由Motyka定义的系数和Renkonen(1938)的生态位的相似系数是一致的,而Spatz(1970)根据Motyka的原理推导的相似系数是不合理的。最后,我们指出,作者和杨义群(1982)提出的关于生态位的相似系数同样可以用来度量植物群落的相似性,这是一种很恰当的度量。

    By applying quantitative methods. we measured the species diversity indices of the regenerated undergrowth in the Chinese fir plantation. The results show that its Shannan-Wiener diversity index (H) is 4.1641; the ecological dominance is only 0.1271; the diversity index of north-west slope is the highest among different habitats; the major soil factors affecting species diversity are organic material, total nitrogen and the thickness of A-layer soil. Six species of broad-leaved trees, including Adinandra millettii,...

Six species of broad-leaved trees, including Adinandra millettii, Evrya loquaina, Castanopsis fargesii and so on. have broad niche species. their breadth index of niche are all more than 0.8; other four species. including Randia cochinchinensis, Liquidambar formosana and so on. have narrow niche. Among the 24 tree species, there are 16 tree species couples whose niche similarity proportions are between 0.8- 1.0. The research will show great significance in constructing new cultivation model of Chinese fir plantation.
