Classification and Spatial Pattern of Rural Multifunction from the Diversify of Construction Land Use:Taking Tongshan District of Jiangsu Province as a Case Study

The development of rural area in suburban(RAS)is comprehensively influenced by the mixed processes of non-farming,local urbanization and rural industrialization and has distinctive multifunctional features on the socioeconomic and resource utilization.Multifunctional reconstruction in the RAS is mainly manifested by changes in the quantity and structure of the construction land use(CLU).We took Tongshan District of Jiangsu Province as the study case.Following the logic of identifying,clustering,and diagnosing,we assessed the functional features of CLU and analyzed the differentiation of the scale and structure of CLU in RAS,with the aim of identifying the types and characteristics of multifunctional development in these regions.This study found that:1)typical RAS were experiencing multifunctional space reconstruction,and their multifunctional value was emerging and highlighted.The CLU was rapidly expanding,and the types of CLU were evolving from single to multiple uses;2)based on the dominant function of diverse rural CLU,we classified RAS into five types,dominated by the following functions,respectively:commercial services,industrial production,residential living,basic support and public service;3)according to the dominant function and spatial pattern,the development types of RAS were classified into agricultural service,comprehensive services,and integrated industries service,showing a circular spatial pattern from the suburbs to distant suburbs.The results can provide policy implication by creating new development impetus from rural multifunction perspective to promote the RAS revitalization.

功能-要素-流视角下的乡村活力空间识别与评价——以中国杭州市临安区为例

Rural vitality is the life force expressed by a combination of endogenous dynamics and external influences. Exploring the complex relationship between rural functions, elements and flows could achieve sustainable rural development. This study constructed a theoretical framework guided by the four functions of production, living, ecology and culture with the support of mobile big data. Furthermore, the network centrality of villages was estimated to reflect the intensity of urban-rural social mobility ties. The results indicated marked spatial disparities in rural vitality, and the coupling of ecological-cultural vitality has a high degree of coherence. Four rural vitality grades were identified: high level(38, 14.08%), medium-high level(66, 24.44%), medium-low level(110, 40.74%) and low level(56, 20.74%), covering 270 administrative village units. The flow intensity of social linkage elements is consistent with rural vitality and the socioeconomic spillover effect of urban centers on neighboring villages was noticeable. Topographic complexity negatively affected the living function, mainly in the T1 and T2 terrain gradients;the rural ecological function was not fully correlated with urban adjacency, and proximity could lead to adverse effects such as urban sprawl and resource destruction. The application of this study is to explore the importance of “flow” by utilizing mobile big data to refine the evaluation unit to the village scale. Accelerating the construction of network coverage and information interconnection and promoting the elemental flow of people, transportation and information between urban and rural areas are important ways to enhance rural vitality.

中国沿海乡村多功能演变及其自然和社会经济影响因素

Rural decline has become a global problem.To address this issue,the division of rural functions and identification of driving factors are important means of rural revitalization.Taking the town area as a unit,this study conducts a division and evolution analysis of rural regional functions in Jiangsu province in coastal China by constructing an evaluation system using the spatial econometric model to diagnose endogenous and exogenous driving factors of rural multifunction formation.The results show that the functions of agricultural supply and ecological conservation have decreased,while the functions of economic development and social security have increased.Agricultural production functions are concentrated in northern and central Jiangsu.The economic development function is mainly based on industrial development,and is the strongest in southern Jiangsu.Social security functions are concentrated in suburban area,county centers,and key towns.High-value areas of ecological conservation are concentrated along lakes,the coast,and hilly areas of southern Jiangsu.The multifunctional development of villages and towns is affected by endogenous and exogenous factors,including economic geographic location,natural resources,economic foundation,human capital,traffic conditions,market demand,infrastructure,and environmental governance.Natural factors have a significant impact on the supply of agricultural products and the formation of ecological conservation functions.The effects of socioeconomic factors on these four functions differ significantly.This study expands the theory of rural development functions,the classification and zoning paradigm,and the quantitative study of driving mechanisms.The results provide a reference for practical value and policy significance for the reconstruction of rural functions and rural revitalization.
