摘要
陕西南部地形复杂,采用小波分析的方法对陕西南部地形观测数据进行分解计算,结果表明:小波分解结果中的高频部分反映了陕西南部地形的局部构造特征,不同频率的分解结果反映了陕西南部不同的地形特征。
The topography in the south of Shaanxi province is very complex. In this article, the wavelet transform method is applied to compute the topography data across the south of Shaanxi, the computed results show that the high frequency part of the wavelet transform have something with the local topographic characteristics in this area, and different scale wansform is the result of different topographic characteristics in the south of Shaanxi province.
