| 摘 要： | 研究以滁州市2007年Landsat TM遥感影像为数据源,分别应用Haar小波和Daubechies小波系中的Db2、Db4小波基,对样区的主要景观类型进行了特征尺度研究。研究结果表明,Haar小波和Db2小波基的二维小波分析均检测出滁州市主城区主要特征尺度存在5个像元150m处,而Db4小波基景观尺度检测效果较差,不适用于对基于遥感数据源的城市景观特征尺度的检测。

| Abstract: | Based on landsat TM image taken in 2007,wavelet analysis was conducted to study the structural features of the urban landscape in the Chuzhou central urban area.Three common wavelets,Haar,Db2 and Db4,were used and characteristic scales were distinguished.The results indicated that the Haar,Db2 wavelet was suitable for detecting characteristic scales of the urban landscape,while Db4 wavelet was not capable of detecting characteristic scales with remote sensing data. |
