马尔柯夫链在江汉平原第四纪沉积环境分析中的应用

应用马尔柯夫链基本原理,在系统统计江汉平原监利县周老镇ZL01钻孔揭示的第四系基础上,结合该区的地质特征,进行了极限概率分析、差值矩阵分析、置换分析和熵分析.根据马尔柯夫链的综合分析结果,总结出江汉平原周老镇ZL01钻孔剖面的第四纪沉积主旋回,发现该剖面主要形成于河流沉积环境,并建立了该区第四系的地方性沉积相模式,为研究该地区的沉积作用、判断沉积环境提供定量的解释依据,对研究江汉平原的变迁历史及其保护和开发利用具有重要意义.

Markov Chain in Quaternary Sedimentary Environment of Jianghan Plain

This paper presents principles and analysis methods of Markov chain. The synthetic analysis has been made by using limit probabilities, difference matrix analysis, replacement analysis, entropy analysis in ZL01 bore of Jianghan Plain. The results exhibit the main gyration of ZL01 bore, and show that the section is mainly formed in the sedimentary environment of river. The paper also expounds the establishment of a land sedimentary facies model of this area, which would be of good use in ration analysis of the sedimentary environment. Meanwhile, it points out that the model is important in finding out the variance history of Jianghan Plain and its protection and application.
