小拉哈文化以小拉哈遗址的第二期遗存为代表,同类遗存在黑龙江省肇源县狼坨子、南山头、卧龙、白金宝和吉林省镇赉县坦途西岗子等遗址亦有发现。依据小拉哈遗址提供的层位关系,同时结合对其它遗址出土材料的比较,可将目前出土的小拉哈文化遗存区分为早晚两期。通过对陶器组合、造型特点和碳十四测年数据等方面的分析,初步判定小拉哈文化的年代应该处于夏至早商时期。 The small Laha culture is represented by the second remains of the site of Little Laha. Remains of the same kind were also found in sites such as Langtuozi, Nanshantou, Wolong and Baiyinbao in Zhaoyuan County, Heilongjiang Province, and Xigangzi, Shunde, Jilin Province. Based on the stratigraphic relationship provided by the Xiaolaha Site and the comparison of the unearthed materials from other sites, the present Xiaolahaha cultural relic can be divided into two phases sooner or later. Based on the analysis of pottery assemblages, modeling features and carbon-14 dating data, it is initially determined that the era of small-scale Laha culture should be in the early summer solstice.
