五大连池老黑山西部熔岩流张裂的多重分形分析

Analysis of Multifractual of Lava's Extension Fracture on the West of Laoheishan Volcano,Wudalianchi

分形与多重分形理论不断兴起与发展,在此背景下,本文应用q阶矩结构分割函数法对我国休眠活火山之一的老黑山西部熔岩流张裂进行了分析,通过多重分形谱曲线,并结合Δα、Δf两个重要的多重分形谱曲线参数,得出Δα=3.736,不接近0点,同时多重分形谱离差Δf>0,熔岩流张裂分布相对密集具有强烈的多重分形特性.为今后定量化研究熔岩流张裂提供了一条新的途径与方法.

As the continuous development of fractal and multifractal theory, this research analyzes the extension tracture of lava on the west of Laoheishan volcano, which is one of the dormant acting volcanoes in China. The conclusion isthat Δα=3.736, which is not approaching 0 point, using the curve line of multifractal spectrum and Δα、Δ, which are two of the most important parameters of this line. Another conclusion is that Δf〉0, the so-called Af is the deviation of multifractal spectrum. Therefore it can be assessed that the distribution of the lava＇ s extension fracture has the character of multifractal. This paper has provided a new method to the quantification of lava＇ s extension fracture.
