We analyzed the baseline for dietary study through stable isotopes in the Gan-Qing (Gansu and Qinghai provinces) region in prehistory. Total 283 animal samples from 4 sites were collected and analyzed. We found that herbivorous δ15N values did not change much in the Hehuang region between 3200 BCE and 2000 BCE, indicating that the range of nitrogen isotopic baseline was relatively stable in different time. The range of herbivorous δ15N values from the Hehuang region around the 2000 BCE is from...
