摘 要:晚更新世晚期的大窑文化遗址经历了气候转干与植被退化。进入全新世后,大青山地区气候转向适宜。距今9400-6900年,该地区出现了植被的部分退化与气候冷干的反复,人类活动范围扩大。距今6900-4000年,大青山地区气候适宜,人类活动的重心主要分布在大青山南麓第一、第二级台地。农业生产水平提高,聚落形态相对成熟。距今4000年之后,大青山地区的气候环境条件不断下降,人类活动大幅减少,聚落遗址数量减少,催生了种植与放牧相结合的混合旱作农业。The site of Dayao culture at the end of the late Pleistocene experienced climatic drying and vegetation degradation.After entering Holocene,the climate in Daqingshan area turned to be suitable.From 9400 to 6900 years ago,there was a partial degradation of vegetation and the repetition of cold and dry climate in this area,and the scope of human activities expanded.During the period from 6900 to 4000 years ago,the climate was suitable,and the center of human activities in Daqingshan area was mainly distributed in the first and second class platform at the southern foot of Daqingshan.With the improvement of agricultural production level,the settlement form is relatively mature.4000 years from now,the climatic and environmental conditions in Daqingshan area continued to decline,human activities were greatly reduced,and the number of settlement sites decreased,which gave birth to the mixed dry agriculture combining planting and grazing.
