古代的“丝绸之路”形成了一个庞大的贸易和交换网络，通过定居的城市社区和移动的牧民，促进了商品和农产品在中世纪中亚的流动。考虑到食物消费模式作为社会经济相互作用的表达，我们分析人类遗骸的碳和氮同位素，以建立饮食摄入量，然后建立同位素生态位模型，以表征饮食多样性，并推断城市居民和游牧牧民社区之间的连通性。在城市群体中可见的低同位素变化与城市社区之间的同位素区别相结合，而不考虑当地的环境条件，这强烈表明本地化的粮食生产系统提供了基本的生存，而不是农产品交换沿着贸易路线。相比之下，游牧社区经历了更高的饮食多样性，反映了对移动的社区典型的各种各样的食品的参与。这些数据表明，城市中心紧密的社会联系明显地汇集了当地的食物产品，并在定居社区内使饮食摄入均匀化，而开放和机会主义的食物生产和流通系统则可能通过更移动的生活方式实现。
The ancient ‘Silk Roads’ formed a vast network of trade and exchange that facilitated the movement of commodities and agricultural products across medieval Central Asia via settled urban communities and mobile pastoralists. Considering food consumption patterns as an expression of socio-economic interaction, we analyse human remains for carbon and nitrogen isotopes in order to establish dietary intake, then model isotopic niches to characterize dietary diversity and infer connectivity among communities of urbanites and nomadic pastoralists. The combination of low isotopic variation visible within urban groups with isotopic distinction between urban communities irrespective of local environmental conditions strongly suggests localized food production systems provided primary subsistence rather than agricultural goods exchanged along trade routes. Nomadic communities, in contrast, experienced higher dietary diversity reflecting engagements with a wide assortment of foodstuffs typical for mobile communities. These data indicate tightly bound social connectivity in urban centres pointedly funnelled local food products and homogenized dietary intake within settled communities, whereas open and opportunistic systems of food production and circulation were possible through more mobile lifeways.
