基于土地利用视角的乡村居业协同多尺度分析——以徐州市为例

“乡村振兴”战略是解决城乡发展不协调、乡村发展不充分问题的重要抓手。居业协同作为乡村人居融合发展的高级形态,其程度能够反映乡村振兴的质量与成效。采用土地利用数据从结构和利用两个维度探索淮海经济区中心城市徐州三个尺度下的居业协同格局,结果表明：（1）徐州市土地在供给方面表现出居业失衡,宅基地供给相对于经营性建设用地优势明显;但由于使用中宅基地的空废,二者利用状态表现得更协同。（2）不同空间尺度下,居业协同状态有所差异,其中乡镇尺度居业空间关系较为稳定,基本维持相对平衡,本文认为乡镇是土地资源配置、实施乡村振兴战略的最佳尺度。（3）后续研究中,居业用地适宜的比例及农用地对居业协同的影响都需要进一步探索。

Multi-scalar analysis on rural housing-industry symbiosis through the lens of land use: A case study of Xuzhou

Industrialization and urbanization have intensified the development transition and spatial restructuring of rural areas, which leads to the problems of urban-rural uncoordinated development and inadequate rural development. The "rural revitalization" strategy proposed by the 19th National Congress of the CPC in 2017 became the starting point of high-quality agricultural and rural development. As an advanced form of rural residents and settlements integrated development, the symbiotic degree of housing and industrial land can well reflect the quality and effect of rural revitalization. In this paper, Xuzhou, the central city of Huaihai Economic Zone, is selected as a case study. Land use data are used to explore the spatial symbiotic degree of residential and industrial land. From two dimensions of structure and function, this paper explores the symbiotic pattern of housing-industry in three spatial scales, namely district/county, town and village. The results show that: (1) The land supply of Xuzhou shows the imbalance of housing-industry. Housing space is more dominant than industrial space. Due to the current vacant land or abandoned land, the residential and industrial lands in use are more symbiotic. We propose to explore ways to allow the conversion of housing land into commercial land to increase the rural industrial space. At the same time, the government should guide the industrial development and revitalize the industrial spaces around central towns to improve the utilization efficiency of rural land. (2) The state of the symbiotic degrees at the three spatial scales has differences. The relationship between residential and industrial space at township scale is relatively stable and basically maintains in a relatively balanced state. It is concluded that township is the best scale for allocating land resources and implementing rural revitalization strategy. Villages exercise their own functions so that all of the villages form an organic combination at township level. Then, they will achieve the state of symbiosis. (3) In the following studies, the appropriate ratio of housing-industry land and the impact of agricultural land on housing-industry symbiosis need further exploration and analysis.
