plant debris

汉语语境:

中国北方新石器时代晚期史前先民的基本食物来源是各类农作物和家畜，但对于不同地区而言，其具体的食物结构却鲜为人知。山东日照两城镇遗址出土的浮选植物标本和植桂体表明，稻米和粟是该遗址龙山先民重要的食物来源，但由于动物骨骼保存较差，今人对他们的肉食来源所知甚少。而采用碳氮稳定同位素法探讨古人的食性和食物结构，对各种同位素含量不同的食物在当时人们食谱中的相对重要性提供了补充定量的数据。

英语语境:

In Neolithic North China, various types of crops and domestic animals were the pre-historic people's basic food source, but the specific diet in different regions was still little known. Plant debris and phytolith specimens obtained from the Rizhao Liangchengzhen site in Shandong by means of floatation showed that rice and millet were important food for the Longshan people of the site. As for their meat source, we have few data because the animal bones excavated from the site were in poor condition. However, the C-N stable isotope method is applied to probing into ancient people's diet character and structure, which has provided supplementary qualitative data for investigating the relative importance of different types of foods varied in the content of isotope in the people's diet at that time.
