摘 要:为探究庆阳市的耕地“非粮化”状况、时空演变格局及驱动因素,以甘肃省庆阳市及8个县区为研究区域。通过地理探测器进行数据分析,利用因子探测及交互探测模型揭示庆阳市耕地“非粮化”的时空演变特征及其成因。结果表明,(1)2017-2021年,庆阳市耕地“非粮化”率由18%上升到26%,存在缓慢增长趋势,耕地“非粮化”的时空变化整体呈现出由低度“非粮化”向中高度“非粮化”逐渐发展的态势。(2)经济发展维度的影响力较为明显,自然禀赋维度的影响力相对较小,两个维度的大部分因子之间的相互作用是双因子增强的结果,说明二者共同作用对耕地“非粮化”水平的影响程度优于单因子。这一研究结果为更好地管控耕地“非粮化”指明了方向,对保障国家粮食安全具有重要意义。In order to explore the situation of“non-grain”cultivation,spatial and temporal evolution pattern and driving factors in Qingyang City,Qingyang City of Gansu Province and 8 counties were taken as the research area.Through data analysis by geographic detector,the factor detection and interactive detection model can reveal the spatial and temporal evolution characteristics of the cultivated land and its causes of“non-grain”cultivation in Qingyang City.The results show that,(1)from 2017 to 2021,the“non-grain”rate of cultivated land in Qingyang City increased from 18%to 26%,and the space-time change of cultivated land is gradually developing from low-degree“non-grain”to medium-grain.(2)The influence of economic development is obvious,the influence of natural endowment is relatively small,and the interaction between the factors of the two dimensions is the result of double factor enhancement,indicating that the influence of the combined effect of cultivated land is better than that of single factor.This research result points out the direction for better control of“non-grain”cultivated land,and is of great significance to guarantee national food security.
