乡村多元价值实现视角下的耕地“非粮化”演变及其驱动机制——以重庆市为例

Spatio-temporal Evolution and Driving Mechanism of Non-grain Cultivated Land for Rural Multi-value Realization:A Case Study of Chongqing

文章在解析乡村多元价值内涵和理清其与耕地“非粮化”关联逻辑的基础上,以重庆市为研究区,通过空间特征分析和空间计量模型分析进一步探讨了2010—2020年重庆市耕地“非粮化”演变过程及其驱动机制,进而提出针对性建议。结果表明:(1)在乡村价值转型的不同阶段,乡村多元价值实现与耕地“非粮化”存在一定的互馈关系。(2)重庆市耕地“非粮化”率从2010年36.87%上升到2020年42.87%,各区县“非粮化”率空间分布趋于均衡,并呈现“西高东低、北低南高”的分布格局,高高集聚区集中在主城都市区并在长时间保持稳定。(3)耕地“非粮化”是在乡村多元价值实现进程中各价值要素综合作用的结果,在乡村要素发挥的多元功能引导下,乡村多元主体对乡村产业结构调整的行为响应最终驱动耕地利用的“非粮化”或“趋粮化”行为。

On the basis of analyzing the connotation of rural multi-value and clarifying the logic correlation between rural multi-value and "non-grain" cultivated land, this paper takes Chongqing as the research area, further discusses the evolution process and driving mechanism of "non-grain" cultivated land in Chongqing from 2010 to 2020 using the methods of spatial characteristics analysis and spatial econometric model analysis, and then puts forward specific suggestions. The results show that: 1) In different stages of rural value transformation,there is a certain mutual feeding relationship between the realization of rural multi-value and the "non-grain" cultivated land. 2) The "non-grain" rate of cultivated land in Chongqing increased from 36.87% in 2010 to 42.87% in 2020, and the spatial distribution of "nongrain" cultivated land in all districts and counties tended to be balanced,showing a uneven distribution pattern of "high in the west,low in the east,low in the north and high in the south". The high concentration areas were concentrated in the main metropolitan area and kept stable for a long time. 3) The "non-grain" cultivated land is the result of the comprehensive action of various value elements in the process of realizing rural multi-value. Under the guidance of the multi-function of rural elements,the behavior response of rural multi-subject to the adjustment of rural industrial structure ultimately drives the "non-grain" or "grain" cultivated land use.
