如何深入浅出讲解变差函数的内涵

How to Explain the Connotation of Variogram in Simple Terms

作为一门地质资源类的专业课程,地质统计学已在多所高校开设。在储层地质建模和地质统计学课程的授课过程中,须特别注重基本概念的讲述,这些基本概念包括空间区域化变量、空间自相关性以及变差函数等。为了让学生更容易理解变差函数概念,文章深入浅出地展现变差函数的物理意义及特点,并以多个实例演示不同空间结构模型的变差函数形态,让学生掌握变差函数的本质。

As a professional course of geological resources,geostatistics has been offered in many universities.In the course of teaching reservoir geological modeling and geostatistics,special attention should be paid to the description of basic concepts,including spatial regionalization variables,spatial autocorrelation and variation function.In order to make it easier for students to understand the concept of variation function,the article shows the physical meaning and characteristics of variation function in simple terms,and demonstrates the form of variation function of different spatial structure models with multiple examples,so that students can master the essence of variation function.
