| 摘 要： | 土地利用是区域经济社会活动的基本形式和重要载体,土地利用变化会对区域社会系统产生重要影响。从土地利用变化视角切入,探究其对干旱区乡村社会恢复力时空演变的影响,对缓解干旱地区乡村人地矛盾、促进其乡村转型发展具有重要现实意义。研究基于恢复力评估分析框架,从社会、经济、人文和基础设施4个方面构建干旱区乡村社会恢复力评价指标体系,并以民勤绿洲作为案例区,综合运用ArcGIS空间分析、地理探测器等方法,分析了石羊河流域重点治理前后民勤绿洲乡村社会恢复力时空演变特征,探讨了土地利用结构和功能变化对乡村社会恢复力的影响。研究结果表明：①民勤绿洲乡村社会恢复力呈现中部和南部乡村不断升高,北部乡村先降低后升高的演变过程;②土地利用结构和功能变化会对乡村社会恢复力时空分异产生显著影响。其中,耕地和生态用地之间的相互转移对恢复力变化方向的影响具有不确定性,2000—2007年草地向耕地转移以及2007—2015年耕地向生态用地转移会提升恢复力;不同时期影响恢复力的主导土地利用功能因子存在差异,流域重点治理前土地垦殖率和人口密度的影响更显著,流域重点治理后生态用地占比和乡村人口人均耕地面积的影响更显著。 |

| Abstract: | Land use is the basic form and important carrier of regional economic and social activities. Land use change will pose a significant influence on regional social systems. Examining the impact of land use change on the temporal and spatial evolution of rural social resilience is of great practical significance for alleviating the conflict between humans and land and promoting the rural transformation and development in arid areas. Based on the analytical framework of resilience assessment, this study constructed an evaluation indicator system of rural social resilience in arid areas from four aspects of society, economy, people, and infrastructure, and took the Minqin Oasis as a case area. ArcGIS spatial analysis, land use transfer matrix, and geographical detector were used to analyze the temporal and spatial change characteristics of rural social resilience of the Minqin Oasis before and after the key watershed management project of the Shiyang River Basin and to explore the impact of structural and functional changes of land use on rural social resilience. The results show that: (1) Rural social resilience of the Minqin Oasis presented different processes of change in different regions. The resilience of the central and southern villages increased continuously, while the northern villages decreased first and then increased. (2) The structural and functional changes of land use have a significant impact on the temporal and spatial differentiation of rural social resilience. From the perspective of the impact of land use change on the change of resilience, the transfer of grassland to cultivated land enhanced the resilience from 2000 to 2007. However, the transfer of cultivated land to ecological land improved the resilience from 2007 to 2015. With regard to the dominant influencing factors of social resilience in different periods, the impact of land reclamation rate and population density on the spatial differentiation of resilience was more significant before the implementation of the key watershed management project, while the impact of ecological land proportion and per capita cultivated land area of rural population was even more significant after the key watershed management project implementation. |
