清代民国时期,农奴制度下的藏族居民在婚姻形态上具有鲜明的民族性、地域性和复杂性,存在着一夫一妻、一夫多妻、一妻多夫等多种婚姻家庭形态。考察西藏居民的婚姻家庭形态变迁,必须将其置于藏族特定历史阶段的生产方式、道德观念、宗教信仰、地理环境等因素中考量。尽管藏族的婚姻与家庭保留了较多的、落后的婚姻形式残余,但其中也有很多合理并与其地域特征相适应的因素。 During the period of the Qing Dynasty and the Republic of China, Tibetan residents under the system of serfdom had distinctive nationality, geography and complexity in the form of marriage. There were many forms of marriage and family, such as monogamy, polygamy and polyandry. When examining the changes in the marriage and family patterns of Tibetan residents, they must be considered in factors such as the mode of production, moral values, religious beliefs and geographical environment in a particular historical stage of Tibetans. Although Tibetan marriages and families retain more and less remnants of marital forms, there are many factors that are reasonable and appropriate to their geographical features.
