摘要
[目的]刻画耕地利用转型变化特征,揭示耕地转型发展规律,为汾河流域耕地资源保护和乡村转型发展提供理论支撑和参考依据。[方法]基于1980年、1990年、2000年、2010年、2020年土地利用遥感影像数据,利用耕地转型速度、转移矩阵和地理探测器方法,分析了汾河流域耕地利用转型的时空分异特征,并探测了其驱动因子。[结果](1)1980-2020年,流域内耕地面积减少10.59万hm^(2),其中,耕地转为建设用地的面积最大,草地是转入耕地最多的地类,占转入总面积的59.37%。(2)1980-2020年,汾河流域耕地利用转型速度呈波动下降趋势,其中中游耕地减少最明显,人地矛盾突出。(3)自然因子对耕地转型影响程度明显强于社会经济因子,其中气温q值最大,达0.72。自然因子之间的交互作用对耕地转型的解释力更强。[结论]汾河流域耕地利用转型受自然和社会经济因素共同影响,先后经历了缓和平稳、转型加剧、矛盾尖锐和收敛平衡不同阶段,空间集聚性特征显著,将指导该流域耕地资源合理、有序利用。
[Objective]The aims of this study are to describe the characteristics of cultivated land utilization transformation,to reveal the pattern of cultivated land transformation and development,and to provide theoretical support and reference for the protection of cultivated land resources and rural transformation and development in Fenhe River Basin.[Methods]Based on the remote sensing data of land use in 1980,1990,2000,2010 and 2020,the spatiotemporal characteristics of land use transition in Fenhe River Basin were analyzed by using the methods of velocity,transfer matrix and geographic detector,and the driving factors were explored.[Results](1)From 1980 to 2020,the area of cultivated land in the basin decreased by 1.059×10^(5)hm^(2),among which the area of cultivated land converted into construction land was the largest,and grassland was the land type converted into cultivated land,accounting for 59.37%of the total area.(2)From 1980 to 2020,the transformation rate of cultivated land use in Fenhe River Basin showed a fluctuating downward trend,among which the decrease of cultivated land in the middle reaches was the most obvious,and the contradiction between man and land was prominent.(3)The degree of influence of natural factors on cultivated land transformation was significantly stronger than that of social and economic factors,and the temperature q value was the largest,reaching to 0.72.The interaction between natural factors had a stronger explanatory power for cultivated land transformation.[Conclusion]Under the influence of natural and social economic factors,the transformation of cultivated land use in Fenhe River Basin had experienced different stages of smooth easing,intensified transformation,sharp contradiction and convergence balance.The spatial agglomeration features are significant,which will guide the rational and orderly utilization of cultivated land resources in the basin.
