【摘要】 以宽甸县2004年土地利用现状数据提取的农村居民点矢量数据为研究基础,利用GIS的空间分析功能,将居民点矢量数据与DEM矢量数据、坡度、坡向以及公路、河流矢量数据叠加,对宽甸县居民点空间分布特征进行定量分析.研究结果表明:①宽甸县农村居民点的分布格局受海拔、坡度、坡向、道路、河流的影响比较明显.②宽甸县农村居民点缺少整体的规划,部分居民点分布在不适宜人们居住的区域,有待调整.因此本研究对今后乡村规划和农村居民点建设具有重要的借鉴意义.更多还原

【Abstract】 Based on land-use data of Kuandian County in 2004,the authors make use of GIS spatial analysis functions,extract rural settlements vector data,stacking settlements vector data with DEM vector data,slope,aspect,roads and rivers vector data,quantitatively analyze the spatial distribution of settlements in Kuandian County.The results show that: ①In Kuandian County,the distribution of rural settlements effected by the elevation,slope,aspect,roads and rivers relatively obvious.②In Kuandian County rural settlements lack of overall planning,some people living in unsuitable areas.So this study has an important reference on the future village planning and the building of settlements in rural areas.更多还原
