| 摘 要： | 水系分维反映了水系的发育程度,体现了河道的复杂程度.以TM遥感数据和分形几何理论为基础,应用图像分析软件ENVI对长白山火山区水系进行了盒维数计算,经统计分析得到了该区四个子区域水系及整个区域水系的分维数.结果表明:长白山火山区水系分维数西部最大D=1.425,东部最小D=1.212;四个分区分维数的差异直接反映了其流...

| Abstract: | The values of fractal dimension of river system reflect their degree of development and complexity of river channel.On the basis of remote sensing data,fractal geometry and image analysis software,the values of box-counting fractal dimension for the radial river system of Changbaishan volcanic area are calculated,and carried out statistical calculations in EXCEL.The region can be subdivided into four distinct areas characterized by different geomorpholo-gic features and their values of fractal dimension als... |
