摘要:
[目的] 分析陕西省土地利用变化及驱动因素,为促进该省土地资源综合优化配置和社会经济可持续发展提供科学依据。[方法] 基于2000,2010和2018年陕西省的土地利用遥感监测数据,通过土地利用动态度、土地利用转移矩阵、空间自相关等方法定量分析陕西省土地利用的时空演变特征,并利用主成分分析法对其土地利用变化的驱动力进行分析。[结果] 各土地利用类型面积均有不同程度的变化。其中,耕地面积下降最多,工矿建设用地面积增速最快,水域面积变化最小。土地利用类型受自然条件的影响,空间差异性显著。农村居民用地、未利用地、耕地、林地、草地的空间聚集性强,水域、城镇居民用地和工矿生产用地的空间集聚性性相对较弱,草地、工矿建设用地形成新的集聚区。陕北高原和关中平原土地利用转移相对频繁,陕南山区土地利用转换相对较小。榆林市和延安市主要表现为耕地向林地和草地转移以及未利用地和草地向工矿建设用地转移,西安市主要表现为耕地和农村居民用地向城镇居民用地转移。土地利用变化的主要因素是城市化发展过程中社会经济的发展以及产业结构的调整。[结论] 陕西省土地利用变化区域差异较大,应因地制宜制定土地利用规划,促进人口—经济—生态之间的协调发展。

Abstract:
[Objective] The land use change and its driving factors in Shaanxi Province were studied to provide a scientific basis for promoting the comprehensive optimization of land resources and sustainable social and economic development. [Methods] Based on the remote sensing monitoring data of land use in Shaanxi Province in 2000, 2010, and 2018, the spatiotemporal evolution characteristics of land use in Shaanxi Province were quantitatively analyzed through methods such as land use dynamics, land use transfer matrix, and spatial autocorrelation, and principal component analysis method to explore the driving forces of the land use change. [Results] The area of each land use type changed in different degrees, among which, the area of cultivated land decreased the most, the area of industrial and mining construction land increased the fastest, and the area of water changed the least. Land use types were affected by natural conditions, and the spatial differences were significant. The spatial agglomeration of rural residential land, unused land, cultivated land, woodland, and grassland was strong, while the spatial agglomeration of water, urban residential land, and industrial and mining production land was relatively weak. Grassland and industrial and mining construction land form new agglomeration areas. The land use transfer in the Northern Shaanxi Plateau and Guanzhong Plain was relatively frequent, and the land use conversion change in the mountainous area of Southern Shaanxi Province was relatively small. The transfer of cultivated land to woodland and grassland, and the transfer of unused land and grassland to industrial and mining construction land were obvious in Yulin and Yan’an City, and the transfer of cultivated land and rural residential land to urban residential land was obvious in Xi’an City. The main factors of land use change were the development of social economy and the adjustment of industrial structure in the process of urbanization. [Conclusion] The regional differences of land use change in Shaanxi Province are great, and land use planning should be formulated according to local conditions, so as to promote the coordinated development of population-economy-ecology.
