湖北随州市黄土岗遗址新石器时代环壕的发掘

Excavation of the Neolithic Surrounding Ditch on the Huangtugang Site in Suizhou City,Hubei

2005年,在湖北随州市黄土岗遗址发现一处新石器时代环壕,整体近似椭圆形,南北长约316、东西宽约235米。壕沟平均宽度15～20、平均深度2.5～3米,最深处超过3.8米。沟内的出土遗物均为陶器。壕沟的形成年代应不晚于屈家岭文化晚期,延用至石家河文化早期,可能具有防御功能。

In 2005, archaeologists carried out drilling and trial excavation on the Huangtugang site in Suizhou City, Hubei Province. The site contains rich cultural deposits, which cover a long period of time and belong mainly to the Neolithic Age. On the site remains a sub-oval surrounding ditch of Neolithic times, with the periphery measuring about 316m （N to S） and 235m （W to E） . It surrounds an area of 57,120 sq m, and is 15-20 m in average width, 2.5--3 m in average depth and over 3.8 m in the maximum depth. The unearthed objects from the ditch are all pottery utensils. Its formation must go back to the time no later than the late Qujialing culture, and it must have functioned for defense down to the early Shijiahe culture.
