Mixed land use advocates that the land has multiple uses and functions, which is an important way to improve the vitality of economic development and the intensive use of land. At present, mixed land use is mainly applied in urban land use evolution and planning practice. With the intensification of urban-rural interaction, the urban-rural boundary tends to be blurred, and the internal structure and function of rural residential land in urban suburbs are gradually diversified, showing significant mixed utilization characteristics. Based on this, this paper attempts to apply mixed land use to the evolution and planning of rural residential land use. On the basis of reviewing the theory of mixed land use and its application, according to the logic of "connotation characteristics-quantitative evaluation-driving mechanism-practice approach", the systematic analysis of the mixed use of rural residential land in urban suburbs was carried out, and the optimization of rural residential areas was proposed. Finally, we take Yaocun village, which is located in the suburbs of Tianjin, as an example to demonstrate the research framework proposed in this paper. The ideas and plans for the mixed land use theoretically enrich the methods and framework for the transformation of rural residential land use, and provide scientific support for the preparation of village planning and the implementation of the strategy for rural revitalization in practice.
