赤峰东山嘴遗址属于夏家店下层早期。该遗址简报有目前这一文化唯一的遗址平面图。从图中我们可以看出两类灰坑：一种是距房址很近的规整的深坑；另一种是距房址较远的不规则浅坑。前者主要出土陶器与农具；后者多出与手工业相关的器物，其中骨针多为完好的。简报认为前者是窖穴，后者是垃圾坑。我们认为前者应为窖穴，但后者应是从事家庭手工业的场所，这里地穴式房址采光极差也可以印证这个推论。通过对另外十几个夏家店下层文化的遗址房屋出土物的分析也发现有农具集中和非农具集中的两类房屋。这种现象还有待更多的资料来证实和解释。 Chifeng Dongshan mouth site belongs to Xiajiadian lower early. The site briefing has the only site plan of the present culture. From the figure we can see two types of pits: one is a regular pit close to the house and the other is a shallow pit far away from the house. The former mainly excavated pottery and farm tools; the latter more artifacts related to the handicrafts industry, of which the bone needles were mostly intact. The briefing thought the former was a cellar and the latter was a garbage pit. We think the former should be pit cellar, but the latter should be engaged in family handicraft industry, where the poor lighting of the cave site can also confirm this corollary. Through the analysis of the unearthed buildings of the other dozen Xiajiadian lower cultural sites, two types of houses with concentrated farm tools and non-farm tools were also found. This phenomenon needs more information to confirm and explain.
