摘要
带状剖面方法使用高程的最大值、最小值、平均值和标准差四个统计参数来定量描述一定区域内的地形起伏特征,并把地形剖面图对线状地形起伏特征的描述转化为对面状地形起伏特征的描述。根据该方法,用ArcView3.3内嵌的Avenue语言开发的带状剖面工具扩展了地形剖面图的绘制功能,实现了带状剖面图的自动绘制。应用到实际的地貌分析中,能准确地反映出高程变化的统计特征,有助于地形与地貌之间空间关系的提取和分析。
The swath profile method uses four statistical parameters including maximum, minimum, average and standard deviation to describe the topographical feature in a certain area quantitatively, and turns the description of the hypsography characteristic of topography in line into the description of topography in a certain area by the topographical profile graph. According to this method, the swath profile tool by the Avenue language embeded in ArcView 3.3 is developed. It expands the function that draws the topographical profile graph and realizes the automatic drawing of the swath profile graph. While being applied to the practical morphometric analysis, it can reflect the statistical characteristic of elevation change accurately and is of advantage for abstraction and analysis of the spatial relationship between topography and landform.
