摘　　要：乡村振兴战略实施及社会主要矛盾转型背景下,乡村景观文化服务(LCS)成为乡村景观演化的重要动因,目前乡村景观空间分异研究与乡村景观功能多样化发展之间存在缝隙。以重庆市典型山地乡村为例,应用乡村游憩数字足迹等多源数据,提出了基于乡村景观文化服务的供给能力(S)、潜在需求(D)及感知偏好(P)相结合的乡村景观分异及类型识别方法,将研究区分为了5种乡村景观识别区,并应用MaxEnt模型解析了不同乡村景观类型中的景观感知偏好的影响因子。结果表明,山地乡村LCS供给、需求及偏好的冷热空间分布差别显著,乡村LCS的S-D-P关系具有显著的集合性和地域性,5种识别区的景观管理需要集体尺度上的价值观、规则和行动;同时发现公众的景观偏好多集中在旱地景观中,而林地景观中的偏好度差异度最大,同时影响水田、旱地及林地景观中感知偏好的环境因素有所不同。研究结果可为快速演化分异的乡村景观管理提供理论支持。Under the background of the implementation of the rural revitalization strategy and the transformation of social contradictions the rural Landscape Cultural Service(LCS)has become an important motivation for the evolution of rural landscape.At pres-ent,there is a gap between the research on the spatial differentiation of rural landscape and the diversified development of rural landscape functions.Taking a typical mountain village as an example,using multi-source data such as rural recreation digital footprint,this paper proposes a rural landscape differentiation and type identification method based on the combination of supply capacity(S),potential demand(D)and perceived preference(P)of rural landscape cultural services.The study area is divided into five rural landscape identification areas,and the MaxEnt model is used to analyze the impact factors of landscape perception preference in dfferent rural landscape types.The results show that the spatial distribution of supply,demand and preference of LCS in mountainous villages was significantly different.and the S-D-P relationship of rural LCS was character-ized by aggregation and regionality.The landscape management in the five identified areas required values,rules and actions on a collective scale;At the same time,it is found that most of the public's landscape preference are concentrated in the dry land landscape,while the preference difference in the forest land landscape is the largest.At the same time,the factors that affect the perception preference in the paddy feld,dry land and forest land are different.This research can provide theoretical support for the management of rapidly evolving and differentiated rural landscape.
