本文通过对唐山市啮齿动物种群的调查,表明整个动物种群及密度与海拔高度的升降有某种程度的一致性。平原地带因地势平缓,动物种群由南向北逐渐升高;深山带因地势复杂,山势险峻,植被及小生境变化频繁,啮齿动物种群随之增加。山前平原分布黑线姬鼠、大小家鼠、大仓鼠及黑线仓鼠;山基底部分布林姬鼠、社鼠;山麓分布岩松鼠、花鼠;山上部分布鼯鼠、棕背(鼠平)。其活动幅度多明显限制在某海拔高程的一定限度中。各种啮齿动物种群因自己的内在生态习性对各种自然因素作选择性的适应。此次调查对各种因素反映的程度与自然符合度之间尚有一定差距,有待今后工作中进一步探讨和完善。
In this paper, a survey of rodent populations in Tangshan shows that there is a certain degree of consistency between the entire animal population and the density and altitude. Due to the gentle terrain in the plain, the animal population gradually increases from south to north. Due to the complicated topography and steep mountains, the rodent population increases with frequent changes of vegetation and niche. Piedmont plains distribution Apodemus agrarius, house mouse size, big hamster and black line hamster; mountain base part of Bu Lin Apodemus, community rats; foothills distribution rock squirrels, rat; Hill part of the cloth zebra, brown back ). The extent of their activity was significantly limited to a certain elevation in certain limits. Various rodent populations are selectively adapted to various natural factors because of their intrinsic ecological habits. There is still a certain gap between the degree to which various factors are reflected in the survey and the degree of natural conformity, which is yet to be further explored and improved in future work.
