    Land use dynamic and driving force analysis of cultivated land change in Mengyin County

    • 摘要: 基于1987、1997和2007年的TM影像,利用土地利用动态度模型和主成分分析法,对蒙阴县1987—2007年的土地利用时空变化特征及耕地变化驱动力进行研究。结果表明:在时间序列上,20年间该区土地利用结构发生了明显变化,林地、城镇村及工矿交通用地面积增加,耕地等其他用地面积减少;在空间上,各类土地利用变化在呈现明显的区域分异,耕地减少去向被开发为林地和城镇村及工矿交通用地的面积较多;驱动耕地变化的因素是经济总量增长、社会发展和农业发展。研究成果可指导蒙阴县土地利用规划,为其生态环境保护提供参考。

       

      Abstract: Based on TM images in 1987,1997 and 2007,applied land use dynamic degree model and the land use general dynamic degrees to promulgate the land use spatial-temporal change characteristic comprehensively in the research area during 20 years.The result indicated that: from the time,land use changes significantly during 20 years,forest land and construction land increase,others decrease.From the space,each type of land use change has a dramatic spatial distribution.Factors which driving cultivated land change are total economic growth,social development and agricultural development.which is helpful for the land planning in Mengyin county and can provide reference for ecological environment protection.
