摘　　要：土地利用转型与农业生产结构调整密切相关,具有互馈关联和交叉耦合的重要特征。如何认知其过程的网络关系已成为响应快速城镇化和乡村转型的一个重要话题,也是乡村振兴所关注的农村焦点问题之一。本文利用四川省土地利用和农村经济统计数据,分析了土地利用转型与农业生产结构调整的特征以及网络关联性。研究结果表明:1)1980—2018年期间,草地和水田减少的面积最多,其土地利用变化率分别为-0.72%和-0.64%,而城乡、工矿、居民用地和林地呈大幅增加,同时粮食作物产量占比大幅下降,而蔬菜产量占比增加了20.43%;2)土地利用转型与农业生产结构调整两大系统之间互馈关联的特征突出,尤其是林地和水域面积的变化同相对应的农产品变化表现出高度的关联性,而旱地变化的关联性具有分异性,突出了当前农业结构由粮食向蔬菜与经济作物转型的趋势;3)四川省五大经济区的土地利用转型与农业生产结构调整网络关联性的空间分布格局差异显著,表现为区域农业发展的主导产品与用地类型相互之间的影响关系最突出,而其余相对较弱。Land use transition and adjustment of agricultural production structure have the important characteristics of complex network nexus and cross coupling.Recognizing the network nexus of their coupling process has become a key point responding to rapid urbanization and rural transformation,and it is also the focus of rural revitalization.Based on the statistical data of land use and rural economy in Sichuan Province,this paper analyzed the characteristics and the complex nexus of land use transition and adjustment of agricultural production structure.Results show that:1)During 1980—2018,the area of grassland and paddy field decreased the most,and the land use change rates were-0.72%and-0.64%respectively.While the urban-rural residence land,industry development land,and forest area increased significantly.Meanwhile,the proportion of grain production decreased the most,while the proportion of the vegetable production increased by 20.43%;2)The network nexus between land use transition and adjustment of agricultural production structure is prominent.Especially the changes of forestland and water area are highly correlated with the corresponding changes of agricultural products.While the changes of dryland are differentiated,which highlights the trend of the current agricultural structure transition from grain to vegetables and cash crops;3)The spatial pattern of the network correlation between land use transition and agricultural restructure is obviously different among the five economic zones in Sichuan Province.The relationship between regional agricultural development leading products and land use types is the most prominent,and the rest are relatively weak.
