Abstract:

After Daxi culture flowering, the ancient culture in the Yangtze Gorges region showed the recession around 5 kaBP, and full recession around 4 kaBP, which corresponds exactly to the transformation process of regional climate from stability to instability. The instability of climate increased evidently in the process of its transformation. The original planting was essentially out of the regional economy. The composition of fishing and hunting always occupied the absolute advantage in this period. The subsistence economy showed highly dependent relationship with natural conditions. In general, during 6～2 kaBP, the subsistence economy in the Yangtze Gorges region showed the evolution characteristics from “fishing and hunting-farming economic” to “fishing and hunting economic”,
and to “fishing and hunting-salt industry economic” again. The ancient culture connotation showed the special phenomenon of “progress during recession” and “transition during recession”. All above, on the one hand, reflect the progressive of the environmental perception and active adjustment of ancient culture; on the other hand, they also reflect distinctly the cultural identities of local environmental adaptability.
