摘要:

关中平原作为我国西部重要的粮食主产区,其耕地利用生态效率研究对协调粮食安全与资源可持续利用之间的矛盾具有重要意义。基于2013—2022年县域面板数据,采用非期望产出Super-SBM模型量化耕地利用生态效率,并结合空间自相关分析与地理探测器方法,系统探究其时空演化特征及其驱动因素。结果表明:(1) 2013—2022年关中平原生态效率整体呈“U”型演变,空间上形成“中部高、西部次之、东部低”的梯度格局,高效率区以西安、咸阳为核心向西扩散,铜川、渭南等地则长期处于低效率状态。(2) 生态效率空间集聚特征显著,高效率集区以乾县向南扩展,低效率集区则稳定集聚于东部。(3) 自然、社会、经济和政策因子协同驱动效率空间分异,其中年降水量、高程等因子影响强度随时间动态演变,城镇化率与农民人均可支配收入促进作用持续增强,且多维因子交互增强效应显著。

Abstract:

As a key grain-producing region in western China, the Guanzhong Plain requires a critical balance between preserving the nation’s food security and sustainable land use. This study employed county-level panel data from 2013 to 2022 to evaluate the ecological efficiency of cultivated land use using the Super-SBM model incorporating undesirable outputs. Spatial autocorrelation analysis and the Geodetector method were applied to systematically investigate the spatiotemporal evolution of ecological efficiency and its underlying driving mechanisms. The results reveal a distinct “U-shaped” temporal trajectory in ecological efficiency, accompanied by a spatial gradient pattern characterized by higher efficiency in the central region, followed by the west. Meanwhile, the east saw lower efficiency. High-efficiency clusters were primarily concentrated in Xi’an and Xianyang and exhibited a trend of westward diffusion. Meanwhile, Tongchuan and Weinan remained in persistently low-efficiency states. Significant spatial agglomeration was also observed, with high-efficiency clusters expanding southward from Qian County and low-efficiency clusters consistently located in the eastern plain. This spatial heterogeneity of ecological efficiency has been shaped by a synergistic interplay of natural, socioeconomic, and policy-related factors. The influence of variables like annual precipitation and elevation demonstrated dynamic temporal variability, while the positive effects of urbanization rate and per capita disposable income of rural residents revealed a sustained upward trend. The interactions among these multidimensional factors yielded pronounced reinforcing effects on ecological efficiency.
