The diversity of regional functions in the county leads to the difference in the degree of regional multi-functional coupling and coordination, and affects the development of rural residential land consolidation. Takes Wannian County, Shangrao City, Jiangxi Province as an example, based on the calculation of regional multi-functional coupling coordination degree, combined with the evaluation results of rural residential land suitability, the consolidation strategies of rural residential areas under different regional multi-functional coupling coordination degrees are analyzed. The results show that: (1) The demand for rural residential land consolidation in Wannian County is affected by the results of regional multi-functional coupling coordination and land suitability to a certain extent; (2) According to this, the existing rural settlements are divided into five categories: reserved development, internal transformation, industrial drive, central village integration and whole village relocation, with an area of 1839.48 hm², 948.99 hm², 1087.73 hm², 342.18 hm² and 23.03 hm², respectively; (3) Corresponding consolidation strategies are proposed for different types of rural settlements. From the perspective of regional multi-functional coupling and coordination, the results of this study can provide new ideas and reference for the development and implementation of rural residential land consolidation and rural revitalization.
