(上接《中国农史》2014年第5期)三、海侵、海退:新石器早中晚期传承与绝传的情况有关海侵的发生,地质气候学的研究测验显示,从距今1.3万年前起,冰川期逐步结束,前北方期和北方期温度上升,海侵则一波又一波地开始,不过,这期间也经历过了数次上升与下降的过程,直到距今近万年前,海洋停止前进并再度稍微退了一点。不过,之后在大西洋期,温度又快速上升,并循着北冰洋的部分冰盖融化,而在距今8200年后,全球水位也快速上升。到了距今7800-7400年间,水位基本上到达现在的海平线。
(Continued from “China’s Agricultural History” 2014 the fifth period) Third, the transgression, sea retreat: Neolithic early and mid-late inheritance and transmission of the case of the occurrence of transgression, geological climatology research tests show that from now on 1.3 thousand years ago, the glacier period gradually came to an end, and the temperature in the northern and northern parts of the country rose. The transgression began to wave after wave. However, it also experienced several ups and downs during this period, Ten thousand years ago, the sea stopped moving and receded slightly again. However, during the Atlantic Ocean, the temperature rose rapidly thereafter, following the melting of part of the Arctic Ocean’s ice sheet. After that, 8200 years ago, the global water level also rapidly increased. To 7800 - 7400 years ago, the water level basically reached the current horizon.
