中国乡村地域系统与乡村振兴战略

乡村地域系统是由人文、经济、资源与环境相互联系、相互作用下构成的、具有一定结构、功能和区际联系的乡村空间体系,是一个由城乡融合体、乡村综合体、村镇有机体、居业协同体等组成的地域多体系统。以乡村地域系统为对象,服务支撑国家乡村振兴战略,为新时期地理学创新研究提供了新机遇和新挑战。乡村振兴地理学研究,亟需以问题为导向、战略为指向,以人地关系地域系统理论和人地系统科学为指导,致力于地表人地系统交互作用下乡村地域系统结构、转型过程、演变机理、分异格局、地域功能,以及乡村振兴途径与模式综合研究,科学把握乡村地域系统类型及其分异规律。本文以全国39164个乡镇为基本单元,采用定量和定性相结合的研究方法,诊断识别了制约中国乡村地域系统可持续发展的主导因子,划分了中国乡村地域系统类型,揭示了乡村地域系统分异格局,探明了不同类型区乡村振兴科学途径。结果表明：① 地理环境、村镇化水平、资源禀赋、人口流动程度和老龄化水平等是乡村地域系统分异的主导因子,反映了乡村发展自然本底特征以及外援动力、内生动力的大小。② 通过主导要素聚类和空间叠加分析,将中国乡村地域系统划分为12个一级区、43个二级区。一级区采用“地理区位+主导要素驱动力/约束力”的方法命名,二级区采用“地域范围+主导要素驱动力/约束力+乡村经济发展水平”命名。③ 不同类型区乡村振兴地域模式和路径不同,乡村振兴战略与规划的落地要因地制宜、分类施策。

Rural regional system and rural revitalization strategy in China

Rural regional system is a spatial system with certain structure, function and inter-regional relationship, which is composed of humanity, economy, resources and environment that are connected and interacted with each other. It is a regional multi-body system, including urban-rural integrity, rural synthesis, village-town organism, and housing-industry synergy. Targeting the rural regional system and supporting the rural revitalization strategy provides new opportunities and challenges for innovation of Chinese geography in the new era. Guided by the theory of regional system of human-land system and the science of human-land system, the research on rural revitalization geography should serve national strategy by finding solutions to problems hindering rural sustainable development, and make contribution to the comprehensive study of rural regional system structure, transformation process, evolution mechanism, differentiation pattern, regional function, and rural revitalization path and model under the interaction of surface's human-land system. There is an urgent requirement to better understand and reveal differences in the types of rural regional system and their differentiation law. Taking 39164 townships in China as research object, this paper used quantitative and qualitative methods to detect and identify the dominant factors that restrict the sustainable development of rural regional systems in China. Then we divided the types of Chinese rural regional systems, revealed the pattern of rural regional differentiation and further proposed scientific approaches to rural revitalization in different areas. Results demonstrate that topographic conditions, climate conditions, ruralization level, land resources endowment, population mobility and aging level are the dominant factors restricting the sustainable development of rural regional system, of which reflects the level of resource endowment, endogenous power and external aid of rural development. Through cluster analysis and spatial overlay of dominant factors, China's rural regional system can be divided into 12 first-class zones and 43 second-class zones. The first-class zones are named by means of 'geographical location + driving force of dominant factors', and the second-class zones are named by means of 'regional scope + driving force of dominant factors + economic development level'. The driving force of rural sustainable development in different regional types are varied. The regional pattern and path of rural revitalization in different types of areas are varied, and promoting the rural revitalization strategy should be based on local conditions to realize the coordination and sustainable development of rural economy, society, culture and ecosystem.
