摘要/Abstract

摘要： 为揭示乡村振兴背景下典型山地丘陵区乡村聚落的时空演化规律与驱动逻辑,以赣南地区为研究对象,综合运用景观格局指数、平均最近邻分析、二元Logistic回归模型与最优参数地理探测器（OPGD）,对2000—2020年乡村聚落的空间格局演变特征及多尺度驱动因素进行系统解析。结果表明,2000—2020年,乡村聚落发展呈由分散的微型聚落向规模化聚落演进的态势,形成微型聚落持续萎缩、小型和中型聚落相对稳定、大型聚落显著扩张的格局。从动态变化上来看,赣南地区乡村聚落的整体发展模式趋于向大型聚落转变,发展方向由西向东扩张,高聚集度区域范围持续扩张,形态结构向不规则化演变。驱动机制主要从区域人地关系主导向社会经济背景主导转型,各驱动因子之间主要表现为非线性增强效应和双因子协同增强效应。其中,坡度是影响聚落分布的主要因子,气候、交通与人口密度因子对聚落空间演变的交互作用显著。这反映出赣南地区乡村聚落具有明显的地域分异特征,需实施“分级分类、分区引导”的空间治理策略,强化交通网络支撑,推进地形适应性聚落建设,以促进赣南乡村聚落格局优化与高质量发展。

Abstract: In order to reveal the spatiotemporal evolution patterns and driving logic of rural settlements in typical mountainous and hilly areas under the background of rural revitalization, this study took the Gannan region as the research object. It comprehensively applied the landscape pattern index, average nearest neighbor analysis, binary Logistic regression model, and optimal parameter geographic detector (OPGD) to systematically analyze the spatial evolution characteristics of rural settlements and their multi-scale driving factors from 2000 to 2020. The results showed that from 2000 to 2020, the development of rural settlements presented a trend of evolution from dispersed micro-settlements to larger-scale settlements, forming a pattern where micro-settlements continuously shrank, small and medium-sized settlements remained relatively stable, and large settlements expanded significantly. Regarding dynamic changes, the overall development mode of rural settlements in the Gannan region tended to shift towards large settlements, with the development direction expanding from west to east. The area of high-aggregation regions continued to expand, and the morphological structure evolved towards irregularity. The driving mechanism mainly transitioned from being dominated by regional human-land relationships to being dominated by socio-economic backgrounds. The interactions among various driving factors were mainly manifested as nonlinear enhancement effects and two-factor synergistic enhancement effects. Among them, slope was the main factor affecting settlement distribution, while climate, transportation, and population density factors had significant interactive effects on the spatial evolution of settlements. This reflected that rural settlements in the Gannan region had obvious regional differentiation characteristics. It was necessary to implement a spatial governance strategy of "hierarchical classification and zonal guidance", strengthen the support of the transportation network, and promote the construction of terrain-adaptive settlements to optimize the rural settlement pattern and promote high-quality development in the Gannan region.
