2001年,黑龙江省文物管理委员会对凤林古城进行了实测和发掘,这次发掘的遗存可以分为早、晚两期。早期遗迹有房址,遗物有陶器和玉器。晚期遗迹有房址、灰坑和城垣,遗物有陶器、石器、骨器、铜器和铁器等。通过发掘,我们了解了这一时期城址、城墙、房址的特殊形式,并进一步认识到这是一种新的文化类型。 In 2001, Heilongjiang Provincial Cultural Relics Management Commission conducted a survey and excavation of the ancient city of Fenglin. The remains of this excavation can be divided into two phases, early and late. Early ruins have room sites, relics pottery and jade. There are sites of late ruins, pits and walls, relics pottery, stone, bone, bronze and iron and so on. Through excavation, we learned about the special forms of city sites, city walls and houses during this period and further realized that this is a new type of culture.
