西南シルクロードと焼畑的水田稲作からひもとくヒマラヤ東部 : 地域体系研究の端緒として

Abstract

This paper analyzes the extent to which the eastern Himalayan world has made itself felt in the following 1) the various Tibet-Burman language groups that are distributed along the Southwestern Silk Road; 2) Wet rice cultivation by the Hani People of Southern Yunnan, and the Apatani People of Arnachal Pradesh, both of which may share the same origin of their swidden wet rice cultivation; 3) the similar tropical monsoon weather of the eastern Himalaya and southern Yunnan. It proposes the working hypothesis that Tibet-Burman language groups like Hani and Apatani may have moved around between the southern Yunnan and the eastern Himalaya in or around B.C. 10 C via the Southwestern Silk Road. One of Hani sub-groups may have also migrated in search for suitable places for swidden wet rice cultivation in hilly areas between the southern Yunnan and the eastern Himalaya.
