基于ArcView的地形分析在新农村建设规划中的应用

Application of ArcView Topography Analysis in the Planning for Construction of New Rural Area

地表的坡度、坡向的分布对城市规划和建设有着多方面重要的影响。利用ArcView软件处理AutoCAD格式的全要素地形图数据,通过地理信息技术建立数字高程模型(DEM),以甘肃省天祝藏族自治县华藏寺镇新农村建设规划项目为例,进行地形坡度和坡向分析,解决新农村建设规划中对建设用地的坡度、坡向的分布和统计问题,为村庄建设提供有效的规划建议。

The distribution of the slope and ascent of the earth＇s surface has influence on the city planning and construction in many ways.With ArcView software the geography diagram data of AutoCAD format was dealt with and the Digital Elevation Model（DEM） was built through the geographical information technique.In this essay the layout project of the new countryside construction of Huazangsi town of Tianzhu Tibetan autonomous county in Gansu Province being taken as an example,the topographical slope and ascent were analyzed to resolve the distribution and the statistical problems in use of the slope and ascent of planning for construction of new rural area,so as to provide programming suggestion for the village construction.
