社会——地理关系下粤西县域耕地流转的时空分异及其驱动机制

Spatiotemporal Differentiation and Driving Mechanism of Cultivated Land Transfer in County Areas of Western Guangdong under the Social Geographic Relationship

文章以粤西地区县域为研究对象,利用2012—2022年的面板数据,通过主成分分析法对耕地流转指标体系降维重归类,利用地理探测器和ArcGIS Pro等工具研究了粤西地区耕地流转的分异特征、影响因素和驱动机制。结果表明:①粤西地区的耕地流转存在着明显的空间分异,呈现“西部高、中部一般、东部低”的三级空间格局,但中部和东部区域的耕地流转差异趋于缩小,不平衡性减弱。②单因子条件下耕地面积、户籍人口、农村集中式供水工程、耕地灌溉面积等指标的解释力明显优于其他指标,双因素交互作用下耕地面积和农业生产总值之间的交互作用最为明显。③粤西地区耕地流转的地理空间分异是农业生产、经济发展、农村人口和农业投资等社会因素共同作用的结果。

Takeing counties in western Guangdong as the research object and based on the panel data from 2012 to 2022,this article uses the principal component analysis to reclassify the indicator system of cultivated land transfer.It studies the differentiation characteristics,influencing factors,and driving mechanism of cultivated land transfer in western Guangdong by the means of geographic detector and ArcGIS.The results show that:1)The cultivated land transfer shows the characteristics of significant spatial differentiation in the western Guangdong,presenting a three-level spatial pattern of"high in the western Guangdong,average in the central Guangdong,and low in the eastern Guangdong".However,the difference in cultivated land transfer between central Guangdong and eastern Guangdong tends to narrow,and the imbalance weakens.2)Under the condition of single factor,the explanatory powers of indicators such as cultivated land area,registered residence population,rural centralized water supply project,and cultivated land irrigation area are obviously better than other indicators.Under the interaction of two factors,the interaction between cultivated land area and agricultural GDP is the most obvious.3)The geographical spatial differentiation of cultivated land transfer in western Guangdong is the result of the combined effects of social factors such as agricultural production,economic development,rural population,and agricultural investment.
