摘要
本文从理论生态学的角度,运用模糊聚类方法,结合生化、动物地理区划和生物种群分布理论,对中国鼠疫菌17种生态型进行了近缘分析,发现某些中国鼠疫菌型具有生物学上的易变性;同时揭示了某些鼠疫菌生态型的营养需求与宿主、地区无关的现象。本文从生态学角度称此现象为居间性,并通过这种居间性探索各生态型衍生变化的关系路经。
On the basis of theoretical ecology, 17 ecotypes of Yersinia pestis in China were analysed by using the method of fuzzy cluster combined with biochemistry, zoogeographical divisionsand the theory of biocommunity distribution and some of these ceotypes found to have varia bility i. bloogical characters.
At the same time, the study also revealed the phenomenon that nutrthonal reqnirement
of same ecotypes were not correlated with both bosts and distries The phenomenon is called interm adiaty'in terms of ecology in this paper, and the correlative pains by which derivation may take piace in different ccotypcs of Yersinia pestis have been reveated throngh this phe nomenon called ''intermediary'.
