基于地学信息图谱的龙口市土地利用动态变化研究

Study on Dynamic Change of Land Use in Longkou City Based on Geo-Information Map

摘要:

阐述了地学信息图谱的内涵及其概念模式，以山东省龙口市为例，在RS和GIS技术支持下，利用1989年和2003年数字遥感图像、土地利用图及自然、社会经济统计数据，建立了龙口市土地利用动态变化信息图谱。根据信息图谱从空间和时间两方面分析了龙口市土地利用动态变化过程，推测出其土地利用变化的主要驱动力。

Abstract:

In this paper, content and conception of geo-information map are introduced. Setting Longkou city in Shandong province as an example, supported by RS and GIS technology, by using digital remote sensing images in 1989 and 2003 , maps showing land use plans, and natural, social and economic statistical datas, information map showing dynamic change of land use in Longkou city is set up. According to information maps, dynamic changes of land use in Longkou city are analyzed from the spatial and temporal parts, and major driving factors caused dynamic changes of land use are predicated.
