摘　　要：不同生物对一个环境因子有不同的生态幅,同一生物在不同生长期对同一环境因子有不同的生态幅。我们基于相关研究,从哲学的角度提出了生物的生态幅波动和遗传变异规律假说:不同生物或同一种生物在不同生长期对一个环境因子的耐受极限与耐受的时间成反比;不同生物或同一种生物在不同生长期的生态幅不是恒定的,如果不同生物或同一种生物在不同生长期,总是生活在生态幅范围内的某一个适点的小范围内,或者频繁生活在生态幅范围外,它们的生态幅都会发生变化,生物在这一过程中将变异,如果繁衍后代将可能导致遗传变异现象。这一假说既可以比较完满地解释环境因子是如何对生物遗传变异产生作用的,进而说明导致生物多样性和生物种内多样性的根本原因以及它们的变化趋势,同时也为人们制造和控制新品种生物提供了一条新思路新方法。Different living beings have different ecological amplitude to one environmental factor, identical creatures have different ecological amplitude to the environmental factor with all its life in different growth period. Based on the research of relationship, from the＂ philosophy, We summarize the hypothesis of law about ecological amplitude fluctuating and hereditary variation of the living beings ; the tolerance limit of deferent living beings or different growth period of all its life of same living beings to one environmental factor is being inverse proportion to time of tolerance ; ecological amplitude of different living beings and its different growth period is not invariable, if different living beings and its different growth period always lives among circle of a bit righter of ecological amplitude, or live frequently outside ecological amplitude, its ecological amplitude will change, the living beings will make a variation in this course, if it multiply the offspring this time, their offspring may cause the hereditary phenomenon. This hypothesis can explain more satisfactorily how function emerges to biological hereditary variation for environmental factor, and then explain the basic reason and tendencies of bio-diversity; and offer a new method and a new assortment for making and control new living beings at the same time.
