摘　　要：从生态保护和建设的角度重构乡村聚落空间,是强化“山水林田湖草”生命共同体,实现生态宜居乡村建设的重要手段。以重庆市荣昌区为例,在分析其乡村聚落空间分异特征的基础上,结合景观生态学理论,运用最小累积阻力模型构建生态保护格局,根据乡村聚落现状布局对研究区生态保护的影响划分乡村聚落调整类型,并提出各类聚落的空间重构策略。结果表明:(1)研究区乡村聚落空间分异特征明显,总体上表现出布局散乱、数量多、规模小、沿河傍水等特征。(2)研究区乡村聚落空间布局现状不利于生态环境保护,将已有的乡村聚落划分为优先整治、限制扩张、适度建设、重点发展4种类型,结合乡村发展实际和区域生态功能定位,提出相应的重构策略。研究结果可为丘陵地区生态宜居乡村建设提供可靠的理论支撑和决策参考。Restructuring rural settlement space from the perspective of ecological protection is the main method of constructing the ecologically livable village and strengthening the community of life which is composed of mountains,rivers, forests,paddy field,lakes and grass. Taking Rongchang District of Chongqing Municipality as an example,the spatial differentiation characteristics of rural settlements were analyzed,the ecological protection pattern was constructed based on the model of minimum cumulative resistance and the theory of landscape ecology. According to the impact of the rural settlements on the ecological protection,rural settlements were divided into different types and spatial restructuring strategies were proposed. The results show that the rural settlements in Rongchang District had significant spatial differences. The rural settlements are characterized by scattered layout,large number,small scale,and near water sources. The current distribution of rural settlements is disadvantageous to ecological environment protection. According to the ecological protection theory,the existing rural settlements were divided into four types:to be restructured,to be expanded with certain limits,to be constructed moderately,and to be developed vastly. The corresponding reconstruction strategies have been proposed accordingly,based on the actual situation of rural areas and the position of regional ecological function. The research results would be useful for theoretical support and decision-making process towards the ecological and livable rural settlements in hilly areas.
