空间变异理论在土壤特性分析中的应用研究进展

Research Progress of the Spatial Variability Theory in Application to Soil Characteristic Analysis

空间变异理论是研究随机变量空间变异性的理论。该理论是建立在地统计学基础之上,其研究的主要对象就是那些在空间上具有一定变异性的随机变量。空间变异理论被广泛应用到土壤学、生态学、地质学、水文学、气象、资源环境及其存在"空间变异性"的领域。对空间变异理论的研究方法进行简要的介绍,并且对空间变异理论在土壤的物理、化学特性及微量元素中的应用研究进行介绍。在对空间变异理论的研究方法和在土壤特性中应用的归纳和分析中,指出空间变异理论在理论和应用中存在的问题并为其提出展望。

Spatial variability theory is the theory of studying space variability of random variable. The main research objects of this theory that based on the geostatistics are those random variables with certain variability on space. The spatial variability theory is widely applied to agrology, ecology, geology, hydrology, weather, resource environment and other fields with ＂space variability ＂. This paper briefly introduces the means of study of the spatial variability theory and the application of this theory in study of physical,chemical characteristics and microelements in soil. By concluding and analyzing the means of study and the application in soil characteristic of this theory, this paper indicates problems existing in theoretics and applications of this theory and gives the expectations.
