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.
