在中国中北部，生存方式从狩猎和采集过渡到以小米为基础的农业在全新世早期和中期之间。为了更好地了解古代环境变化如何影响这种转变的生存策略和人类活动在区域到地方的水平，我们进行了孢粉学和岩性分析的放射性碳定年沉积物岩心从洛阳盆地，河南省西部。我们的孢粉学结果表明，植被从阔叶落叶林（9230-8850 cal yr BP）草原草甸植被（8850-7550 cal yr BP），然后与稀疏的树木草原（7550-6920 cal yr BP）。岩性分析还表明，洛阳盆地的河漫滩的稳定后，~8370 cal yr BP可能吸引了人们进入盆地，促进了粟为基础的农业出现在裴李岗文化时期（8500-7000 cal yr BP）。一旦农业实践出现，气候最佳后7550卡年BP可能促进了仰韶文化（7000-5000卡年BP）在中国中北部的扩张。随着农业生产的加强，与人类活动有关的花粉类群，如荨麻，大量增加。
In north-central China, subsistence practices transitioned from hunting and gathering to millet-based agriculture between the early and middle Holocene. To better understand how ancient environmental changes influenced this shift in subsistence strategies and human activities at regional to local levels, we conducted palynological and lithologic analyses on radiocarbon-dated sediment cores from the Luoyang Basin, western Henan Province. Our palynological results suggest that vegetation shifted from broad-leaved deciduous forest (9230–8850 cal yr BP) to steppe-meadow vegetation (8850–7550 cal yr BP), and then to steppe with sparse trees (7550–6920 cal yr BP). Lithologic analyses also indicate that the stabilization of the Luoyang Basin’s floodplain after ~8370 cal yr BP might have attracted people to move into the basin, promoting the emergence of millet-based agriculture during the Peiligang culture period (8500–7000 cal yr BP). Once agricultural practices emerged, the climatic optimum after ~7550 cal yr BP likely facilitated the expansion of the Yangshao culture (7000–5000 cal yr BP) in north-central China. As agriculture intensified, pollen taxa related to human disturbance, such as Urtica, increased in abundance.
