摘　　要：为分析山东省土地利用变化格局,以期为土地管理决策、生态环境保护和社会经济协调发展提供科学依据,利用山东省1997—2008年各市土地利用详细变更数据,选取农耕用地、牧草用地、园林用地、水域用地、城乡居住及工矿用地、交通用地和未利用土地等7种土地利用类型,在定量模型支持下对山东省不同时段及其内部不同区域土地利用类型变化格局进行了模拟和分析。结果表明:1997—2008年,山东省未利用地、耕地减少幅度较大,水域用地面积增长最显著;土地利用类型变化动态度为0.96%;水域、交通用地、未利用地变化较为显著,其变化动态度分别为25.85%、2.26%和-2.14%。此外,各市耕地、园地、未利用土地和牧草地的相对变化率相距悬殊,证明山东省土地利用类型变化具有显著的区域性差异。该研究揭示了山东省土地利用变化的时空特征,对土地可持续利用、生态农业建设与人地协调发展具有重要意义。The study analyzed the change of land use structure in Shandong Province in order to provide ascientific basis for ecological environment protection,land management decision-making and social economicdevelopment.Variations in land use of different periods and different land types,including cultivated land,garden land,grassland,water area,urban and rural residential and industrial and mining land,traffic land andunutilized land,were analyzed based on the data from 1997 to 2008 with the help of mathematical models.Theresults indicated that the changing rate of unutilized land and cultivated land decreased significantly from1997 to 2008.However,the most significant increasing land type was water area.The dynamic degree of landuse change was 0.96%.Water area,traffic land and unutilized land changed more significantly,and theirdynamic degree were 25.85%,2.26% and-2.14%,respectively.Moreover,the relative change rate ofcultivated land,garden land,grassland and unutilized land of every city in Shandong Province was different.The results indicated that the regional difference of land use change in Shandong Province was obvious.Theresearch revealed the special-temporal characteristics of land use change in Shandong Province and had agreat significance on sustainable utilization of land and coordinated development of human and land.
