摘　　要：用胴体重数据作次数分配，参考繁殖及其它生长发育指标，将大耳猬（Ｈｅｍｉｅｃｈｉｎｕｓａｕｒｉｔｕｓ）区分为幼年组、亚成年组、成年Ⅰ组和成年Ⅱ四个不同年龄组．统计表明，各年龄组间胴体重重叠较小，均值差异极显著，可作为划分大耳猬年龄组的依据．依胴体重为主要指标确定的年龄组，分析了体重、耳长、晶体重、颅基长、颧宽、眶间宽、鼻骨长与年龄的关系．结果表明，耳长、晶体重、颅基长和颧宽的计量值可作为区别幼年猬、亚成年猬和成年１组猬的年龄指标，而体重、眶间宽和鼻骨长只能区别出幼年组和亚成年组．The age identification of long-eared hedgehog(Hemiechinus auritus)in Wuliangsuhai regiong of inner Mongolia are studied.With the body weight excluding viscera(bwev)as a major indicator and the reproduction as reference, the long-earde hedgehogs are divided into 4 age groups. The standards of these age groups are listed.below:Juvenile:BWEV is less than 119 g, mean 73. 88±6. 135; Sexually inactive;Subadult: BWEV is 120～199 g, mean 164. 35±5. 799; Sexually inactive;Adult I: BWEV is 200～279 g, mean 235.75±8.588;all reproductive;Adult Ⅱ: BWEV is more than 280 g, mean 326. 83±12. 128:all reproductive.The ear length, lens weigth,skull length and zygomatic width of the long-eared hedgehog also could be used for identification of the age of juvenile, subadult and adult Ⅰ; but the body weight, interorbital width and nasals length only could be used for distinguishing of the age between iuvenile and subadult.
