Social transformation of the 7th millennium Neolithic communities in Mesopotamia and its relationship with the climatic changes

通过对叙利亚东北部Tell Seker al-Aehimar地区的田野调查，研究了美索不达米亚第七千年新石器时代社区的社会转型及其与气候变化的关系。考古发掘和相关研究重建了聚落历史：聚落建立于PPNB晚期，在PN早期pre - proorot Hassuna阶段成为最大聚落，在原-Hassuna阶段逐渐变小，并在此之后形成最终的abaon不。实地考察还揭示了公元前7千年早期相当有利的气候条件的证据。研究表明，公元前7千年晚期的人类定居放弃和新石器时代群落的转变可能反映了8.2ka事件，这是一个全球性的气候恶化事件。

Social transformation of the 7th millennium Neolithic communities in Mesopotamia and its relationship with the climatic changes were investigated through fieldwork at Tell Seker al-Aehimar, northeast Syria. The excavations and related studies resulted in the reconstruction of the settlement history as follows: the settlement, which was established in the Late PPNB, became largest at the Pre-Prorot Hassuna phase of the early PN, and became smaller in the Proto-Hassuna, with the final abaondont afterwards. The filedwork also revealed evidence of rather favourable climatic condition in the early 7th millnnium BC. The present study suggests that the settlement abandonment in the late 7th millennium BC and the later transformation of the Neolithic communities might reflect the 8.2ka event , a global climatic deterioration episode.
