基于RS和GIS的土地利用/覆被变化及驱动力分析——以新津县为例

     

摘要

Land use/cover change(LUCC) has a profound impact on the development of regional nature, economy, and eco-environment as well. Taking Xinjin as an example, this paper, on the basis of remote sensing and GIS software, probes into the spatial pattern of land use/cover change from 2004 to 2009 through quantitative and qualitative analysis. The results indicate that area of arable land and other land decreases, while that of woodland, residential land and rivers increases; there lies mutual transformation among various land use types; the immerse spatial changes have taken place in land use and cover, and the structure of land uses has stepped into the rapid adjustment period. Policies, urbanization as well as economic development are the major driving force for the change of land use types.%土地利用/覆被变化对于区域的自然、经济和生态发展有着深刻的影响.本文以新津县为例,借助遥感和GIS软件,从定量和定性的角度分析新津县2004-2009年土地利用/覆被变化空间格局.结果表明:耕地和其他用地面积减少,林地、居住用地和河流水域面积增加;土地利用类型之间存在相互转换的情况;土地利用覆被的空间变动较大,土地利用结构处于快速调整期.政策制度、经济发展、城镇化进程是土地利用类型发生变化的主要驱动力.
