摘要
用分形与多重分形的方法研究地球化学场中地球化学指标的分布规律具有重要的意义。本文运用多重分形矩方法研究了新疆塔里木盆地艾协克 -桑塔木南地区 2 0 0 0 km2 内采集的 2 0 85个土壤样中 2 0项油气化探指标的多重分形谱函数形态特征。结果表明 ,主要成油气指示指标的多重分形谱基本上呈单一“钩状”,显示较弱的多重分形或单一分形 ;而其他指标多显示较强的多重分形特征。这些性质在研究区广泛存在 。
It is of great significance to study the distribution of geochemical indexes in geochemical fields by means of non-linear approaches. In this paper, a typical multifractal model called the method of moments is applied to study the distribution patterns according to the multifractal spectrum forms obtained based on 20 oil and gas indexes from 2085 soil samples over 2000 km 2 in the southern Aixieke-Sangtamu Region in Xinjiang, China. The results indicate that the major oil and gas indexes helpful for petroleum prospecting have relatively weak multifractality or these indexes are nearly single-fractal ones, whereas the other indexes are strongly multifractal. This property is universal throughout the study region and it is believed to provide insight into the evaluation of petroleum resources.
