通婚圈是用来描述择偶规律和结构的重要“指标”，表示某一社会群体成员配偶对象的来源范围。它可以从“社会距离”和“地理距离”两个不同的维度进行定义和测量。通婚圈的变化反映婚姻交往的变化，通婚圈扩大意味着人们择偶范围的扩大，远距离交往交流的扩展；通婚圈缩小意味着人们的择偶空间变小，地域交往封闭或不对称。文章以蒙藏汉聚居区青海湖南岸蒙古村为田野调查点，从人类学视角对其通婚圈的形成、特点及其发展变迁进行了调查研究。认为，蒙古村的通婚圈按照通婚形式可分为族内通婚和族际通婚，而通婚圈的变迁主要表现在通婚辐射半径逐渐延长、两性通婚圈的不对等和通婚民族趋于多样化等方面。

A intermarriage circle is an important "indicator" used to describe the pattern and structure of mate choice, indicating the range of sources of spouses for members of a particular social group. It can be defined and assessed with two different dimensions, "social distance" and "geographical distance". The changes in a intermarriage circles reflect the changes in marital interactions, with the expansion of a intermarriage circle implying the expansion of the scope of people's choice of spouses and the expansion of long-distance interactions and exchanges, while the narrowing of a intermarriage circle implying the reduction of the scope of people's choice of spouses and the blocked or asymmetrical geographic interactions. The article takes the Mongolian village on the south shore of Qinghai Lake, with Mongolian, Tibetan and Han people living there, as a field research site, and investigates the formation and characteristics of the intermarriage circles there as well as their development and changes from an anthropological perspective. It is believed that the intermarriage circles in Mongolia village can be divided into intra-ethnic and inter-ethnic intermarriage according to the forms of intermarriage, and the changes of the intermarriage circles are mainly reflected in the gradual extension of the radius of intermarriage circles, the asymmetry and diversification of intermarriage of ethnic groups, and so on.
