区域土地利用变化信息图谱模型研究

信息图谱为区域土地利用变化提供了一种谱系化、定量化与定位化相结合的研究方法，借助信息图谱模型探讨区域土地利用变化及其时空过程的多维性与复杂性，为土地利用变化的驱动力诊断、机理模型与预测模型的构建提供科学依据。选取吉林省长岭县为研究区，在遥感与GIS技术支持下，以土地利用时空演变模式、空间扩展过程、景观特征等为框架，建立土地利用变化信息图谱模型，对图谱方法在土地利用变化研究中的应用进行实证分析。

Research on Geo- Informatic Tupu Model of Regional Land Use Change

Recently,geo-informatic Tupu has become the hot spot in geo-informatic science,which couples many advanced disciplines,such as cartography,computer science,geographic information science etc..A series of digital images or graphics are used to explore the spatial structure and the spatial-temporal rules of geographical objects and phenomena.The model of geo-informatic Tupu can visibly display essence attributes of complicated problems tersely,distinctly.It is characterized by multi-dimension graphics,dynamic of spatial-temporal etc..Most existing models of land use change confine their research to transformation of land use types,statistic analysis of land quality change and static explanation of spatial pattern.Taking Changling County of Jilin Province as research area,this paper discusses regional land use change and multi-dimension character of spatial-temporal process recurring to informatic Tupu model.Furthermore,the basic Tupu cell in different spatial scales by kinds of digital graphics is generalized,deepening the data mining and multi-dimension expression of land use change internal rules.Thus it would provide scientific evidence for driving forces diagnosis,mechanism model and forecasting model in land use change.Spatial-temporal evolvement patterns,spatial expanding process and landscape quality of land use change compose the main frame of land use change informatic Tupu model by means of RS and GIS.
