摘要:

明确乡村功能与定位, 可以为加快农业农村现代化发展、有效推进乡村振兴战略实施提供决策参考。通过构建乡村多功能综合评价指标体系,以甘肃省县域为研究单元,采用ArcGIS自然间断点法、纵向比较系数等方法,对全省乡村功能发展水平进行综合评价。结果表明:(1)2000—2019年乡村综合功能指数平均值不断上升,乡村综合功能增强,总体呈现东高西低的空间格局;农业生产功能逐步增强,粮食作物主产区范围不断扩大,并不断向陇中、陇南地区方向移动;经济发展功能呈现西北高东南低的空间格局,外围区县发展受到中心城区辐射带动作用;居住生活功能异质性明显,大部分区县乡村居住生活水平较低;生态保育功能受政策影响,逐步改善且高值区不断扩大。(2)乡村综合功能2010年后差距扩大,但各功能变异系数整体趋于稳定,变化幅度较小。(3)乡村多功能纵向比较系数空间分布特征显著,部分地区之间有一定的空间集聚特征,总体表现为增强趋势。根据甘肃省乡村功能类型区呈现的地域差异化提出了相应的调整策略。

Abstract:

Clarify rural functions and positioning, can accelerate the modernization of agriculture and rural areas, and provide decision-making reference for effectively promoting the implementation of the rural revitalization strategy. In this paper, by constructing a comprehensive evaluation index system of rural multi-function, taking the county area of Gansu Province as the research unit, using the ArcGIS natural discontinuous point method, longitudinal comparison coefficient and other methods, a comprehensive evaluation of the development level of rural functions in the province is carried out. The results show that:(1)From 2000 to 2019, the average values of the rural comprehensive function index continued to rise, the rural comprehensive function was enhanced with an overall spatial pattern of high in the east and low in the west. The function of agricultural production was gradually enhanced, and the scope of the main food crop production areas continued to expand and moved to the direction of Longzhong and Longnan areas. The economic development function presented a spatial pattern of high in the northwest and low in the southeast, and the development of peripheral districts and counties was driven by the radiation of the central urban area.The heterogeneity of residential and living functions was obvious, and the living standards of most districts and counties were low in rural areas. The ecological conservation function was gradually improved due to the influence of the policy, and the high-value area was constantly expanding. (2)The variation coefficient of each function tended to be stable as a whole. (3)The spatial distribution characteristics of the longitudinal comparison coefficients of rural multi-functions were significant, and there were certain spatial agglomeration characteristics between some regions.

Key words: rural multi-function, rural revitalization, type identification, urban-rural integration, Gansu Province
