| 摘 要： | Pollen, plant seeds and phytoliths from an AMS dated sediment profile at the Xishanping site indicate that the cultivation of rice might start no later than 5070 cal. a BP in the region of Tianshui, Gansu Province. It continued from 5070 to 4300 cal. a BP. This is so far the oldest and the most northwestern record of cultivated rice in Neolithic China, which extends the known region of prehistoric rice cultivation at least 2° longitude to the west. This finding provides important evidence for reconstructing the cultivation region of rice at 5000 a BP （an important time period）, and its spreading history in East Asia, during the Neolithic.

| Abstract: | Pollen, plant seeds and phytoliths from an AMS dated sediment profile at the Xishanping site indicate that the cultivation
of rice might start no later than 5070 cal. a BP in the region of Tianshui, Gansu Province. It continued from 5070 to 4300
cal. a BP. This is so far the oldest and the most northwestern record of cultivated rice in Neolithic China, which extends
the known region of prehistoric rice cultivation at least 2° longitude to the west. This finding provides important evidence
for reconstructing the cultivation region of rice at 5000 a BP (an important time period), and its spreading history in East
Asia, during the Neolithic.
