伴随着智能手机在山区乡村的快速普及，使用短视频社交媒体已经成为村民重要的休闲方式，这促使乡村闲暇生活在时间和空间两个维度上产生了一系列变化。论文以秦巴山区的蒲陈村为例，采用统计分析、问卷调查和访谈法，对短视频社交媒体迅速发展背景下山区乡村闲暇生活的时空变化进行了分析。从时间维度来看，首先，使用短视频社交媒体造成乡村闲暇生活群体化的沉溺，村民绝大部分闲暇时间都被使用短视频占据；其次，由于短视频社交媒体的可选择性与可逆性，乡村的闲暇生活呈现舞台化的时间展演，真实的生活被在线重置；再次，由于内容制作与播放技术的变革，闲暇生活的时间被压缩，乡村生活的焦虑感增加。从空间维度来看，这种影响使得闲暇生活出现从“在场”到“缺场”，闲暇空间虚拟化；从“熟人圈”到“生人圈”，闲暇交际扩大化；从“群体”到“个体”，闲暇生活个体化等一系列空间转向。这种闲暇生活在时空上的变化，带来村庄发展凝聚力下降、责任伦理弱化、空间规划重整等一系列改变。研究对信息化背景下如何提升乡村发展内生动力，提高群众幸福感具有重要意义。

With the rapid popularization of short-video in mountainous villages, watching short-videos has quickly become an important way of spending leisure time for village residents, which has caused a series of changes in their daily life. In a case study of Puchen Village in the Qinling-Daba Mountains, we used statistical analysis, questionnaire survey, and interview methods to analyze the popularization of short-video both through time and across space. Temporally, change can be observed in the following three aspects. First, short-videos cause the addiction of village residents. In most of their leisure time, village residents watch short-videos. Second, due to the selectivity and reversibility of short-videos, leisure life on the countryside shows a kind of false image of performing on the stage. Last, due to the revolution of content creation and playback technique in short-videos, the time of leisure life is compressed, meanwhile, village residents' anxiety for life is increased. Spatially, there are also three changes caused by the use of short-videos on life. The first is a virtualization of leisure time, which shows a change from "presence" to "absence". Second, the use of short-video broadens the scope of communication from the circle of acquaintances to strangers. Third, from group activity to individual activity, people's leisure life tends to become individualized. These changes reduce the cohesion of village development, weaken the sense of responsibility and ethics of village residents, and change village spatial planning.
