Rice, domesticated in the Yangtze River Basin, was introduced to the Guanzhong Plain, and became prominence alongside millets during the Longshan period (ca. 4600-4000 B.P.). This study analyzes flotation samples from the Yangyuan site, revealing a significant abundance of charred rice grains and spikelet bases, surpassing those found at other contemporaneous sites in the Guanzhong Plain. The high concentration suggests substantial rice utilization by the site's ancient inhabitants. The Yangshao period, was marked by rice use influenced by external factors, whereas during the Longshan period, local inhabitants in the Guanzhong region gradually adopted the uses of rice as a self-sustaining practice, with possible regional transport of rice. These findings offer valuable insights into the agricultural practices and dietary preferences of the Neolithic Guanzhong Plain, highlighting the region's evolving civilization and its mixed agriculture of rice and millets.

新石器时代晚期（约公元前 4600-4000 年）关中地区大规模水稻利用的证据：习阳原遗址案例研究


水稻在长江流域驯化，被引入关中平原，并在龙山时期（约公元前 4600-4000 年）与小米一起成为突出品种。本研究分析了阳原遗址的浮选样品，揭示了大量烧焦的米粒和小穗基，超过了关中平原其他同时代遗址发现的浮选样品。高浓度表明该遗址的古代居民大量使用稻米。仰韶时期的特点是受外部因素影响的水稻使用，而在龙山时期，关中地区的当地居民逐渐采用水稻的使用作为一种自给自足的做法，并可能进行水稻的区域运输。这些发现为新石器时代关中平原的农业实践和饮食偏好提供了宝贵的见解，突出了该地区不断发展的文明及其水稻和小米的混合农业。
