【摘要】 舒哈特和施密特提出了语言传播的波浪说，这一假说认为语言的传播像石头在水中激起的波浪，由中心向四周扩散，距离中心越近，传播力度越强，距离中心越远，传播力度越小。卡瓦利–史弗萨、王士元对太平洋群岛语言传播的研究证明了传播距离和传播力度的相关性，也证明了波浪说假说的有效性。田野调查证明，在中国西南地区，由于高山峡谷的阻隔，语言波浪传播有难度，茶马古道的兴起促进了西南官话的传播和内部统一，也证明了语言传播还有另一种模式，即古道网络传播模式。更多还原

【Abstract】 Schuchardt and Schmidt proposed the wave theory of language propagation, suggesting that language propagation is like waves created by a stone thrown into water, radiating from the center outward. The closer to the center, the stronger the propagation, whereas the farther away from the center, the weaker the propagation. CavalliSforza and Wang Shiyuan’s research on language transmission in the Pacific Islands has demonstrated the correlation between transmission distance and intensity, thereby validating the wave theory hypothesis. Field investigations have shown that in the southwestern region of China, language waves are impeded due to the barriers of high mountains and canyons; the rise of the Tea Horse Road promoted the dissemination and internal unity of Southwest Mandarin,thus proving the existence of another mode of language dissemination, namely the network transmission mode along ancient routes.更多还原
