基于耦合关系的县域乡村发展格局与优化——以寒亭区为例

基于评价体系和耦合关系，以寒亭区为例探讨县域乡村发展格局及优化，发现：①多数村庄得分较低，中高值村庄集中于寒亭区中南部，各子系统得分结构具有差异化特征，社会经济方面对乡村发展影响较大但空间分异也更明显；②子系统间、子系统与指标间均有一定耦合关系，指标之间的协同优化有助于实现子系统的高效提升；③相当一部分村庄呈中低值、强耦合特征，发展有赖于区域性优势带动与补偿为重点、邻近村庄优势溢出与合作发展为补充的外部带动，高-高集聚区应从产业着手带动低-低集聚区，高-低/低-高集聚村庄应促成邻近村庄合作发展行业、协同治理乡村、共同向高-高集聚转化。此外，耦合关系视角下的合作与优化应注重实际，以科学实现乡村振兴发展。

RURAL DEVELOPMENT PATTERN AND OPTIMIZATION IN COUNTY REGION BASED ON COUPLING RELATIONSHIP: A CASE STUDY OF HANTING DISTRICT

Combined with multi-source data such as statistics, remote sensing, research, etc., based on evaluation index system and the perspective of coupling relationship, according to the analysis framework of county rural development mode and optimization with coupling relationship embedded, this paper takes Hanting district as an example to conduct empirical discussion and optimization analysis. Results show that: 1) The scores of most villages in Hanting district are relatively low. From the perspective of spatial distribution, the villages with higher scores are mainly concentrated in the south-central part of Hanting District, while the scores of remote villages in the north and east of Hanting district are significantly lower, with a center periphery structure as a whole. 2) There is a certain coupling relationship between the subsystems and between the subsystems and the indicators. For example, indicators such as road network density, life service industry have good explanatory power to the social and economic subsystems after interaction. Only the characteristics of villages, especially the rural governance, are relatively independent. Above analysis shows that more efficient rural development can be achieved through the collaborative optimization of different indicators; 3) A large number of villages show the characteristics of low value and strong coupling relationship, and their development needs certain external power based on the results of external coupling relationship.
