摘要

The Peiligang culture (ca.7000-5000 cal BC) is the earliest Neolithic culture in the middle Yellow River valley and represents the emergence of cereal farming in the region [1].It has long been considered representative of millet farming [2],which requires a dry field,a certain amount of rainfall,and minimal crop management,but new records reveal that mixed farming of millet and rice (Oryza sp.) took place during this period [3].Therefore,it is possible that millet farming coexisted with mixed farming in the Peiligang culture rather than one or the other.The environmental conditions required for mixed farming should be different from those required for millet farming,because rice generally requires more soil moisture and nutrients than millet.Thus,there is a need to know how these agricultural modes were distributed in these sites and what the influencing environmental factors were.However,crop assemblages from the different Peiligang culture sites have rarely been comparatively studied previously;therefore,the spatial distribution patterns of millet and mixed farming are still unknown.
