基于IPAT-S脚本语言的土地利用情景分析及其应用

    Land use scenario analysis based on the IPAT-S script language method and its application

    • 摘要: 建立一种土地利用情景分析方法,该方法以土地利用转换系统最小变动为原则,对不同土地利用的情景设置,利用线性目标优化的Markov链方法生成逐年土地利用面积转换矩阵和各土地利用类型面积。IPAT-S脚本语言实现了上述方法,并提供了上述方法与土地利用空间格局模拟进行耦合的接口。应用上述方法对海淀区2002~2015年土地利用变化进行了多情景分析,结果表明不同的土地利用情景设置对土地利用结构具有明显影响,城镇和工矿用地的集约度对耕地和园地面积的缩减速度具有决定性的作用。

       

      Abstract: The land use change scenario analysis method is established through linear goal program optimized land use area transition matrix produced by Markov chain. The method is based on the principle of minimal change of the land use type conversion system. With the method the annual area transition matrix among the land use types and the total area of each land use type can be calculated under different scenario setting. The method is implemented through IPAT-S script language. Land use changes from 2002 to 2015 was analyzed under four scenario setting schemes in Haidian District, Beijing. The results show that the scenario settings strongly influence the land use structure; the land use intensities of urban and industrial land are the most decisive factors to the decrease of arable and orchard land.
