摘要: 三峡库区是独特的移民与生态敏感地理单元,探究库区耕地绿色低碳利用时空格局及驱动因素,为实现区域耕地生态保护和粮食安全提供参考。采用DEA-EBM模型、全局空间自相关以及地理探测器模型,分析2005~2022三峡库区耕地绿色低碳利用时空格局,并揭示其驱动因素。研究结果显示:(1)耕地绿色低碳利用测度值整体呈波动上升趋势,空间格局呈现高水平区片状聚集,低水平区点状分布的非均衡特征。(2)耕地绿色低碳利用存在空间自相关性,并呈现“负集聚-正聚集”的趋势规律,2005和2010年耕地绿色低碳利用水平空间呈负相关,区域差异显著。2015和2022年空间呈正相关,区域出现聚集现象,且耕地绿色低碳利用水平空间聚集不断增强。(3)社会经济、耕地禀赋条件、农业现代化、自然环境和农业生产条件等多因素共同影响研究区耕地绿色低碳利用时空格局,其中农业机械化水平和乡村人均GDP对耕地绿色低碳利用时空格局的影响起主导作用。因此,应从推进适度规模经营,提高农业机械化水平;改善农业生产条件,提升农业科技服务能力;推动数字化平台建设,促进耕地利用碳减排等方面推动三峡库区耕地利用绿色低碳发展。

Abstract: The Three Gorges Reservoir Area is a special geographic region that is distinguished by ecological sensitivity and immigration. In order to achieve regional cultivated land ecological preservation and food security, this study examined the spatiotemporal pattern and the associated driving factors of green and low-carbon utilization of cultivated land in the reservoir area. The geographical detector model, global spatial autocorrelation, and the DEA-EBM model were used to investigate the spatiotemporal pattern of cultivated land low-carbon and green utilization between 2005 and 2022 and to identify the factors that may influence these patterns. The findings showed that: 1) There was a non-equilibrium feature indicated by the measurement values of green and low-carbon utilization of cultivated land, which displayed an overall fluctuating rising trend with a spatial pattern characterized by high-level clustered areas and low-level scattered locations. 2) The green and low-carbon utilization of cultivated land exhibited geographic autocorrelation, displaying a "negative aggregation - positive aggregation" tendency. Between 2005 and 2010, there was a negative spatial link between the amount of cultivated land used for green and low-carbon purposes and notable regional variations. It demonstrated a positive geographic correlation with new aggregation phenomena in 2015 and 2022, and the spatial aggregation of the amount of farmed land used for low-carbon and green purposes had been steadily increasing. 3) The degree of agricultural mechanization and per capita GDP in rural areas were identified as the two main factors that jointly influenced the spatiotemporal pattern of green and low-carbon utilization of cultivated land. Other factors included socioeconomic conditions, cultivated land endowment, agricultural modernization, the natural environment, and agricultural production conditions. In order to improve the green and low-carbon development of cultivated land utilization in the Three Gorges Reservoir Area, it is advised to encourage moderate-scale operation and increase the level of agricultural mechanization.The agricultural production conditions should be improved and the capabilities of agricultural technology services should be enhanced. It is encouraged to develop the digital platforms to facilitate the reduction of carbon emissions in cultivated land utilization.
