多点模拟算法与试验对比分析

与基于变差函数的传统地质统计相比,多点地质统计学能够很好的用于复杂几何形态地物的建模,而且还有更好的计算速度。本文讨论了多点地质统计,模拟算法(SNESIM)的基本原理以及在其基础上的各种改进。另通过实例分析了SNESIM模拟算法的工作原理及对各种改进算法的比较,提出了一些模拟时的建议。最后,对多点模拟的理论和应用前景作了展望。

Multi-point Statistics, Algorithm and Simulation Analysis

Compared with the traditional geostatistics based on variogram model, multiple-point simulation not only can be perfectly applied to the modeling of geographical objects which have complex geometry structure, but also has faster speed in simulating. This paper discussed the fundamental principle of multiple-point geostatistics and its simulation algorithms (SNESIM), and compared to improve simulation algorithms. The conceptual arguments are further substantiated by an example in third section. The efficiencies of various improved algorithms are also compared in this example and some suggestions are followed. We then conclude our paper with a summary and give potential applications of multiple-point simulation to remote sensing in section 4.
