世界农业起源可以概括为两种基本模式，一种是农业是在当地采集狩猎经济基础上发展起来的，如中东“新月形地带”、中国、中美洲、安第斯一亚马逊河地区、美国东部、非洲撒哈拉地区、西非热带雨林地区、埃塞俄比亚以及新几内亚；另一种是本地农业的发生是周围其它地区农业扩散的结果，如欧洲大陆以及北美的Great Basin地区（图一）。

Two patterns are used to represent the origins of agriculture in the world, either agriculture independently evolved from the local hunter-gathering or agriculture introduced from the surrounding area. Of perhaps ten instances of agriculture origin known worldwide, the northern China is the only one where it does not seem to unfold in situ from local hunter-gatherers. In this article, we are trying to rebuild a whole picture of agriculture development in the reaches of Hulu and Xihanshui by floatation. The results suggest that Panicum miliaceum was firstly domesticated in Dadiwan Phase I, prospered in the Late Banpo of Early Yanshao Culture and then was replaced by Setaria italica since Miaodigou of Middle Yangshao Culture. This indiactes that hunter-gathering was quite prevalent with few domesticated seeds during 8 -7kyr BP, but it turned into developed agriculture in the period of Late Banpo after 6. 2kyr BP. Linking seed ubiquity and statistical analysis, stone tools, cumulative probability of 14C dates, and archaeological sequence gap with climate change in northern China, the author hypothesizes that drier and colder climate may trigger the transition from hunter-gathering to agriculture in northern China.
