摘要
综合花粉、炭化种子等生物指标记录可以提供有关早期植被与农业活动方面的信息。研究显示,下河遗址地区在距今5300～4700 cal a BP之间植被类型以草原为主,仅在河谷地区与山区有少量乔木生长;该地先民在仰韶时代晚期农业活动以旱作农业为主,广泛种植粟类作物,伴随少量黍类作物;另外,较多数量草木犀植物种子的出现可能暗示该地先民利用植物资源饲养牲畜,但仍需进一步研究,以获得更多证据的支持。
The data of pollen and carbonized crop seeds may provide information of early vegetation and agricultural activities. It appears that the area of Xiahe featured a steppe environment with a few groves in the river valleys and mountains in 5300 - 4700 ca/ BP; people of the late Yangshao period cultivated dry crops, mainly foxtail millet, but tempered with broomcom millet. The presence of a large quantity of seeds of melilotus plants indicates that these people exploited them to raise their herds, but this point awaits confirmation from other lines of evidence.
