通过对十二桥文化成都平原类型和渝东类型典型遗址所出动物骨骼的可鉴定标本、最小个体数和肉量估算的统计来考察其生业方式,结果显示前者的肉食资源以家畜为主,而后者则以狩猎为主。与香炉石文化的生业方式进行比较,并认为在早期文明阶段,同一考古学文化的不同类型其生业方式不尽相同,而不同的考古学文化间的生业方式则可能趋同。
Through the 12th Bridge culture Chengdu Plain and the typical ruins of eastern Chongqing animal identifiable specimens, the smallest individual number and the amount of meat to estimate the statistics to examine the method of their employment, the results show that the former predators of the meat-based livestock , While the latter mainly hunting. Compared with the practice mode of censer stone culture, we think that in the early stage of civilization, different types of the same archaeological culture have different ways of producing their own jobs, and different archeological cultures may converge.
