| 摘 要： | 对最近取得的中国南海大陆坡上的火山地形的等高线进行分维测量 ,发现火山及其附近的等高线具有稳定的分维数。利用分维数可以将火山及其附近的地形分成三类 :火山口附近、较陡峭的火山腰部和火山附近较平坦的海底。它们的分维数均低于大陆上等高线的一般分维值 ,平均为 1 .1 1 8。说明玄武岩火山即便不很古老 ,仍可具有标度不变性 ,并且与附近海底一起接受了较厚的海底沉积后 ,又具有了略为不同的分维数。

| Abstract: | A fractal measurement was made to the contours of the sea floor volcano of South China Sea, which shows that the contours of the volcano and its vicinity have stable fractal dimensions Using fractal dimension the topography of the volcano and its vicinity can be divided into three parts: the volcanovent, the steep moutainside of the volcano and the plane sea floor near the volcano Their fractal dimensions are about 1 118 which are lower than those of the land This indicates that the basalt volcano has scale inflexibility even it is not very old, and it has a fractal dimension with little difference after receiving thick marine deposit |
