讨论了中原新石器时代文化遗址14C年代序列的代表性;分析了新石器古文化与古气候的演变;根据陕西扶风案板遗址(傍龙寺)的孢粉资料,结合冰川前进、冰缘现象等因素,重建了代表中原地区的12～3kaB.P.的古年均气温和古年降水量曲线;又根据古文化与古气候关系的数学模型,进行了数学模拟。认为,在降水量超过500mm(主要因素)时,年均气温超过13℃是关中地区史前古文化繁盛的必要条件。

In this paper, we shall discuss the relationship between the paleoculture and paleoclimate of the middle of China in Neolithic Age. By means of the data about paleopollen and the glaciers, we give paleoclimate (the temperature and the precipitation) of the middle of China. The temperature about 10 ka B.P. had been same with today, but the precipitation reached present standard until 8 ka B.P. Therefore the Neolithic Culture was began. According to the data of ¹⁴C dating in various sites, we give the temporal sequence about the ups and downs of Neolithic Culture in the middle of China. We disscoved the fallowing basic facts. First, the colder climate (Δ t =0℃, Δ t is the temperature difference from today) cause downs of the culture, even ended the sequence of the culture in Neolithic Age. The warmer climate (Δ t =2℃) cause ups of the culture. Second, the colder climate cause the removal of the ancients, and the mixture together among different cultures, thus also cause the birth of new culture. Third, the paleoclimate contraled the development of the culture in Neolithic Age. In this paper, we also give a math model on the relation between the paleoclimate and the paleoculture, and give a result of the simulation.
