长江干流全长6300余千米,是中国第一大河流与世界第三长河。它发源于青海省唐古拉山北麓,流经西藏、四川、云南、湖北、湖南、江西、安徽、江苏等省区,在上海市注入东海,流域面积达180799平方千米。青藏高原和长江中下游是我国湖泊最多的两个地区,而长江中游平原则是淡水湖分布最为集中的区域,主要有鄱阳湖、太湖、洪泽湖、洞庭湖等。拙文所探讨的原始文化和氏族部落,主要是长江流经的这些省区,而又侧重于四川及以下省区。
The total length of the Yangtze River trunk more than 6,300 km, is China’s largest river and the world’s third river. It originated in the northern foot of the Tanggula Mountain in Qinghai Province and flows through the provinces of Tibet, Sichuan, Yunnan, Hubei, Hunan, Jiangxi, Anhui and Jiangsu provinces. It injects into the East China Sea in Shanghai and covers an area of 180,799 km2. The Qinghai-Tibet Plateau and the middle and lower reaches of the Yangtze River are the two most abundant lakes in China. The middle reaches of the Yangtze River are the most concentrated areas for freshwater lakes. They are mainly Poyang Lake, Taihu Lake, Hongze Lake and Dongting Lake. The original culture and clan tribes discussed in this essay are mainly those provinces where the Yangtze River flows and focus on the provinces of Sichuan and below.
