摘　　要：探究差异化乡村振兴路径下村域土地利用时空变化特征及其驱动机制,对于优化土地利用格局和制定乡村振兴路径有重要意义。以长江流域浅丘河谷区2个地形地貌相似、历史发展情况接近、乡村振兴路径迥异的行政村——芳阴村和横山村为例,基于无人机航测和多期Google Earth卫星影像,从土地利用转移、核心用地扩张模式、像元级地块属性和边界二值变化等视角综合探讨了两村在2017~2021年的土地利用变化特征,并引入地理探测器模型,从自然、社会经济、政策因素等多个方面定量归因。结果表明:(1)研究期内两村均经历了较为剧烈的土地利用变化过程,以蔓延式的园地扩张为主,最后芳阴村和横山村分别形成了农旅融合型和农林复合型的发展格局,并且芳阴村的土地利用变化过程较横山村更具多样性和均衡性。(2)像元层面上,芳阴村的地块属性和边界变化均较为剧烈,且二者在超50%的村域范围内存在显著的空间集聚效应,而横山村仅地块属性变化较为明显,地块边界变化度整体低于芳阴村。(3)村域土地利用变化受到自然、社会经济和政策多重因素的交互影响,不同乡村振兴路径下村域土地利用变化的驱动类型和驱动解释力度存在差异,对于有明确政策区划驱动的芳阴村而言,政策因素占据了主导地位的解释效力,而没有明确政策区划的横山村,自然因素则更具有解释力。Exploring the changing characteristics of land use over time and space and their driving attribution in village areas under different rural revitalization paths is of great importance for optimizing land-use patterns and formulating rural revitalization paths.Two administrative villages with similar topography and geomorphology,close historical development but quite different rural revitalization paths-Fangyin and Hengshan villages in the shallow hill valley area of the Yangtze River Basin are taken as examples.Based on unmanned aerial vehicle(UAV)aerial surveys and multi-period Google Earth satellite images,the land-use shifts,expansion patterns of core land,binary changes of parcel attributes and parcel boundaries at the pixel level were synthesized to explore the characteristics of land-use change in the two villages from 2017-2021.Along with a geodetector model was introduced to quantify the drivers from various aspects such as natural,socio-economic and policy factors.The results show that:(1)Both villages underwent a dramatic land-use change process during the study period,mainly spreading expansion of the orchard.Fangyin and Hengshan villages respectively formed the development pattern of integrated agro-tourism and integrated agroforestry,and the land-use change process in Fangyin was more diverse and balanced than in Hengshan.(2)At the pixel level,both parcel attributes and parcel boundaries changed dramatically in Fangyin,and there was a significant spatial clustering effect between the two at over 50%of the village area,while only parcel attributes changed obviously in Hengshan,and the degree of parcel boundary change was overall lower than in Fangyin.(3)Land-use change in village area is influenced by the interaction of multiple factors,such as natural,socio-economic and policy factors.There are differences in types of drivers and the strength they can explain to land-use change in the village area under different rural revitalization paths.In the case of Fangyin,which has a clear policy zoning drive,
