【摘要】 两汉时期，河西地区逐步改变了以游牧业为主的经济模式，转变为农业与畜牧业并重的发展模式，旨在应对因统治区域扩大和民族风俗差异带来的军事与行政挑战。通过文献分析可见，汉代河西地区的畜牧结构以牛、羊、鸡、鱼为主，体现了农牧业侧重点的变化及饮食习俗的交融。河西地区的自然条件和牲畜习性等客观因素决定了畜牧品种的选择，而经济结构的变化、牲畜的投入回报率和特殊功能等主观因素推动了畜牧结构的形成与细化。畜牧结构变化促进了农牧业发展规模化、牲畜利用科学化以及社会阶级化，此三方面均体现了两汉政府对河西地区政治统治和军事职能的重视，农牧业成为二者顺利运行的物资保障。更多还原

【Abstract】 During the Han Dynasty, the Hexi region gradually transformed its economic model from one dominated by pastoralism to a development model that equally emphasized both agriculture and animal husbandry. This shift aimed to eliminate military and administrative barriers caused by the expansion of the territory and differences in ethnic customs. Through literature analysis, it is evident that the livestock structure in the Hexi region during the Han period was primarily composed of cattle, sheep, chickens, and fish, reflecting the changing focus of agriculture and animal husbandry as well as the blending of dietary customs. The natural conditions of the Hexi region and the habits of livestock, among other objective factors, determined the choice of animal breeds. Meanwhile, subjective factors such as changes in the economic structure, the return on investment from livestock, and the special functions of animals, drove the formation and refinement of the livestock structure. The changes in the livestock structure facilitated the large-scale development of agriculture and animal husbandry, the scientific use of livestock, and the social stratification. All three aspects demonstrate the Han government’s emphasis on political control and military functions in the Hexi region, with agriculture and animal husbandry providing essential material support for effective governance and defense.更多还原
