利用5250 ~ 4300 cal a BP期间甘肃西山坪遗址的花粉、种子和植物岩等考古生物学指标，重建了该遗址的作物类型和农业特征。西山坪的农业活动在5100 cal a BP开始加强。在距今5070 cal a BP的中国最西北地区出现了最早的史前水稻种植。针叶树的突然消失和栗树的扩张很可能是大约4600 cal a BP的针叶树选择性采伐和栗树栽培的结果。在4650 ~ 4300 cal a BP之间，西山坪地区存在谷子、糜子、水稻、小麦、大麦、燕麦、大豆和荞麦8种作物类型，覆盖了东亚和西亚两个起源区的主要作物类型。不仅小麦和大麦被批准传播到中国西北，而且新石器时代中国最早的复杂农业出现在甘肃天水。
The crop types and agricultural characteristic are reconstructed using the archaeobiological proxies of pollen, seed and phytolith at Xishanping site in Gansu Province between 5250 and 4300 cal a BP. The agricultural activity strengthened in Xishanping from 5100 cal a BP. It appeared the earliest cultivation of prehistoric rice in the most northwest China at 5070 cal a BP. The sudden disappearance of conifers and expansion of chestnut trees is likely to be the result of selective hewing of conifers and cultivation of chestnuts at about 4600 cal a BP. There existed 8 crop types of foxtail millet, broomcorn millet, rice, wheat, barley, oats, soybean and buckwheat at Xishanping between 4650 and 4300 cal a BP, which cover the main crop types of the two origin centers of East and West Asia. Not only has the wheat and barley been approved to spread to northwestern China, but the earliest complexity agriculture in Neolithic China appeared in Tianshui, Gansu Province.
