内蒙古中南部岱海地区考古学文化的发展受到环境条件的制约。原始农业文化的兴起与发展对应于全新世暖期的暖湿条件;农业文化的间断、南移与由农向牧的转变与4～35kaBP发生的变冷、变干的突变事件相对应;而原始农业文化阶段中间每一次文化的间断、侵入、融合总是可以在气候变化中找到相应的变化阶段,与短期寒冷事件的开始或结束对应。

The central-southern part of Inner Mongolia which lies in the edge of monsoon area of northern China is sensitive to the climatic change. It is important to research the relationship between the environmental change and the changes of pre-historical cultures in the region.The archaeological research in the central-southern part of Inner Mongolia indicates that the development of pre-historical cultures in the study area is divided into two phases.The first one is the period of primitive agricultural culture from ca1.7ka BP to ca1.3.5ka BP. The second is the period of farming-grazing transitional culture from cal.3.5ka BP to present. The change of the land use from farming to grazing happened in ca1.4-3.5ka BP.Environmental change is the major driving force for the development of archaeological cultures, such as land use patterns, the growth or decline of agriculture comparing to the pasturage culture in this area. The primitive agricultural cultures were developed and flourished during the warm and humid Holocene Megathermal Period. The sub-phases or interruption of the culture during the primitive agriculturalphase are responded to the phases of climatic change during the Holocene MegathermalPeriod. The transition of land use from farming to grazing duringcal.4ka BPto 3.5ka BP was a result of theabrupt cold-dry event that ended the Holocene MegathermalPeriod.
