摘要/Abstract

摘要： 深刻解读耕地利用转型内涵,基于乡村振兴与耕地利用转型的系统逻辑构建相关评价指标体系,运用探索性空间数据分析（ESDA）和标准差椭圆（SDE）等方法,对2002年、2007年、2012年和2017年淮海经济区耕地利用转型效度进行评测,据此揭示乡村振兴战略背景下耕地利用转型的时空格局及转型路径。结果表明：（1）15年间淮海经济区耕地利用转型呈现整体上升、区域均衡的时空格局。（2）耕地利用转型空间集聚现象明显,南北差异显著。空间转型集聚程度逐渐减弱,功能转型呈现先降低后升高、再降低又趋于平缓的态势。（3）耕地利用转型呈现东北—西南格局,以徐州市为区域重心,在南北方向上持续收缩、东西方向上不断平移,导致转型空间形态呈C状分布;系统要素的交流耦合渐进增长且上升通道具有收缩趋势,最终形成“分散—聚拢—分散—聚拢”重叠形态的转型路径。建议研究区未来发展重点聚焦转型发展内源动力的协调融合,引导耕地利用转型由“C形”扩散转向“O形”收敛的圈层式包容增长格局,并不断提升耕地多功能融合增益的共享程度,将地理系统的均衡机制转化为乡村振兴的现实效能。

Abstract: The connotation of cultivated land use transition is deeply interpreted, and the relevant evaluation index system is constructed based on the systematic logic of rural revitalization and cultivated land use transition. This paper uses the methods of exploratory spatial data analysis (ESDA) and standard deviation ellipse (SDE) to evaluate the effectiveness of cultivated land use transition in 2002, 2007, 2012 and 2017 of Huaihai Economic Zone, so as to reveal the spatial-temporal pattern and path of cultivated land use transition under the background of rural revitalization. The results indicated that: (1) The cultivated land use transition showed a spatial-temporal pattern of overall rise and regional equilibrium during the past 15 years in the study area. (2) The spatial agglomeration of cultivated land use transition is obvious, and the difference between north and south is significant. The agglomeration degree of spatial transition is gradually weakened, and the functional transition shows a trend of decreasing first, then increasing, again decreasing and fainally tends to be stable. (3) The cultivated land use transition presents a northeast-southwest pattern, with Xuzhou as the regional center of gravity, which continuously shrinks in the north-south direction and shifts in the east-west direction, resulting in a C-shaped distribution of transition spatial form; the exchange coupling of system elements gradually increases and the ascending channel has a shrinking trend, and finally forms a transition path of "dispersion-gathering-dispersion-gathering". It is suggested that the future development of the study area should focus on the coordination and integration of the internal driving forces of transformation and development, and guide the cultivated land use transition from "C-shaped" diffusion to "O-shaped" internal collection, a circle inclusive growth pattern, and constantly improve the sharing degree of multi-functional integration benefits of cultivated land, and transform the balance mechanism of geographical system into the practical efficiency of rural revitalization.
