摘要:
提出一种使用音高和时值对沿分水线布设的地形剖面线进行分析的方法.以5 m分辨率的数字高程模型(DEM)数据为基础,选取神木县、绥德县、延川县、富县县、宜君县、淳化县等6个典型研究样区,并选择安塞样区对实验结果进行验证.研究结果表明:6个样区分水线剖面线的声音指标存在差异,其声音模式与实际地貌类型存在明显的对应关系;7个声音指标可以直接进行地貌类型的区分,安塞与绥德样区地貌类型最接近,欧式距离为最小值48.456.说明声音指标可以用来分析分水线剖面线特征,比单一的高程信息蕴涵更多的地形起伏、转折信息,可以从乐理角度整体刻画地貌类型.
Abstract:
A method of using pitch and time value to analyze the characteristics of terrain profile along the watershed is proposed. Based on the 5 m resolution digital elevation model(DEM)data, six typical study areas, Shenmu County, Suide County, Yanchuan County, Fuxian County, Yijun County and Chunhua County, were selected for the experiment, and Ansai sample is selected to verify the experimental results. The research results show that there are differences in the sound indexes of the Catchment Boundary Profile of the six sample areas, and there is an obvious corresponding relationship between the sound mode and the actual geomorphic types; the seven sound indexes can directly distinguish the geomorphic types, and the geomorphic types of Ansai and Suide sample areas are the closest, and the minimum European distance is 48.456. Therefore, the sound indexes can be used to analyze the characteristics of Catchment Boundary Profile, and it can also contain more relief and turning information than a single elevation information. It can describe the overall landform type from the perspective of music theory.
