摘要: 探究新型城镇化与耕地利用生态效率的耦合协调关系对促进城乡融合发展和生态文明建设具有重要意义。以湖北省79个县级单元为研究对象,运用熵值法、非期望产出SBM模型和耦合协调度模型探究了2000~2018年新型城镇化水平与耕地利用生态效率时空演变特征,并揭示两者间时空耦合关系。结果表明:(1)湖北省县域新型城镇化水平呈现缓慢波动上升的趋势,空间上呈现以武汉为中心的“核心-外围”的格局。(2)湖北省耕地利用生态效率整体处在较低水平但呈现明显递增趋势,空间上呈现“中东部高,西部低”的分布特征。(3)湖北省县域新型城镇化水平和耕地利用生态效率的耦合协调度表现出缓慢增长态势,截止2020年,绝大多数县域的耦合协调等级达到了勉强协调及以上水平;空间上“东西”差异逐渐明晰。未来湖北省应因地制宜地推进城镇化建设和耕地可持续利用,并建立统筹协调机制以积极推进生产要素的跨域流动。

Abstract: Exploring the coupling coordination relationship between the new-type urbanization process and the farmland utilization eco-efficiency is of great significance for urban-rural integration development and ecological civilization construction. Taking 79 counties in Hubei Province as the research objects, this paper explored the temporal and spatial evolution characteristics of the new-type urbanization level and the farmland utilization eco-efficiency from 2000 to 2018. The entropy method, SBM-undesirable model and coupling coordination degree model were adopted. The results showed that: (1) The county level of new-type urbanization showed a slow upward trend with minor fluctuations. Spatially, there was a "core- periphery" pattern centered on Wuhan. (2) The overall farmland utilization eco-efficiency was at a relatively low level, but it showed a significant increasing trend. The spatial pattern tended to be stable with a general characteristic of high in the central and eastern and low in the western. (3) The coupling coordination degree showed a slow upward trend. By 2020, the coupling coordination level of the majority of counties had reached a barely coordinated or higher level, and the spatial differences of the coupling degree in the "east-west" direction were gradually apparent. In the future, Hubei Province may promote the urbanization construction and sustainable farmland utilization according to local conditions, and establish a comprehensive coordination mechanism to actively promote the cross-regional flow of production factors.
