2012、2013年在宝鸡石鼓山墓地发掘的M3、M4两座竖穴壁龛墓非常有代表性,即两座墓葬规模相似,均有熟土二层台,高于二层台的东、北、西三面设壁龛,南面无壁龛。以往在关中地区虽然也有类似的发现,但是在讨论墓葬形制与族属的关系方面显得并不太严谨。本文通过梳理不同类型的竖穴壁龛墓,结合这种墓葬形制的起源和传播来探讨壁龛作为一种表现身份等级的产物,并不是体现姜姓戎人的一种葬俗特征,并推测石鼓山墓地的族属可能与碾子坡文化有着一定联系。 In 2012 and 2013, the two cemetery niches M3 and M4 excavated at the Shugushan cemetery in Baoji are very representative. The two tombs are similar in scale and both have the second floor of the mature land, which is higher than the east and north of the second floor. , West side set niche, south niche. Although similar discoveries have been made in the Guanzhong area in the past, the relationship between the tombs and the tribes seems less rigorous. This paper discusses the niche as a product of identity class by combing different types of vertical niche tomb and combining the origin and spread of such a burial pattern, The clan of Shuguishan cemetery may have some connection with the culture of Nianzi slope.
