As an important potential space for improving the utilization efficiency of land resources, land consolidation of rural residential areas is an important part of promoting sustainable rural construction. Towns are the social, economic and cultural centers of the region. The relationship between towns and villages restricts the space potential of rural residential development while the relationship between villages and land parcels reflects the suitability of the layout of rural residential areas and the coordination of resource utilization. In the context of promoting the construction of "New Village" and harmonizing urban and rural development, this study integrates a hierarchy "town-village-land parcel" into a proposed strategy analysis framework to facilitate the spatial association of the behavior subjects in rural areas and the coordination among impacts of different spatial scale factors on land consolidation in rural residential areas. Meanwhile, this study constructs an evaluation system of rural residential land consolidation potential from aspects such as the development of town radiation, the suitability of the village layout and the coordination of land use and applies it to evaluate contemporary programs aiming at promoting the rural residential land consolidation based on the analysis of the elements and structure of rural residential land system. Finally, the study conducts a case study in Xinyi city, Jiangsu province. As a result, the rural residential land consolidation area within the city has been classified into five categories: the priority consolidation area, the key consolidation area, the moderate potential tapping area, the optimal consolidation area and the special consolidation area. Corresponding land consolidation modes and optimization means have further been discussed in order to provide a useful reference for the general rural residential land consolidation programs and promote the sustainable and harmonious urban and rural development.

| 土地利用协调性C | 用地结构C1 | 居民点用地比重 C11 | I=Ji/Si | 表征评价单元土地利用结构的合理度,居民点用地比重越大,居民点分布越集聚 |
| 基础设施用地比重 C12 | I=Hi/Si | 评价单元内基础设施用地面积与总面积之比,基础设施用地比例越大,村庄用地结构越合理 | ||
| 土地利用形态C2 | 距生态敏感区距离 C21 | 实际测量 | 表征评价单元邻域的生态环境质量,评价单元距生态敏感区越近,越不适宜进行农村居民点布局 | |
| 建设用地增长率 C22 | 反映评价单元的建设用地对外扩张速度。Ki表示评价单元第i年的建设用地面积;n为年数。建设用地增长率越大,评价单元建设用地对外扩张越迅速 | |||
| 道路用地占比 C23 | I=Ri/Ki | 反映村内道路拥有量,道路面积占比越大,评价单元交通越便利 | ||
| 居民点本底C3 | 人均居民点面积 C31 | I=Si/Pi | 反映评价单元土地利用集约度,人均居民点面积越大,土地利用集约度越低 | |
| 斑块密度 C32 | I=Wi/Si | 反映农村居民点的空间分布特征。Wi为评价单元i的居民点斑块数量;Si为评价单元i的面积。斑块密度越大,农村居民点分布越集聚 |
