Abstract:

Chinese bamboo resources distribute mainly in south area of Qinling-Huaihe line. According to the study of archaeological materials and historical literatures, the bamboo distribution area in China has changed distinctly since 5 000 a B.P.. Before Tang dynasty, there distributed much bamboo in Yellow River Valley. The north boundary then was at north latitude 39-40°. But today it is at 35°N, moved back toward south for about 4～5°N. The reason is that climate has been getting colder and drier than 5 000～1 000 a B.P.. Bamboo can be used to indicate climate transition as its sensitivity. Being climate changing warm in the present age, it will be much favourable introducing bamboo to Yellow River Valley.

Key words: Yellow River Valley, bamboo resources, distribution in history
