摘要
地统计学近年来成为空间分析的重要工具 ,其应用领域广泛分布在自然科学的众多领域。系统地论述了地统计学理论方法的进展 ,给出地统计学的总体理论框架 ,它包括局部估值、不确定性预测、随机模拟及多点地统计学四部分。并指出所有这些方法的理论基础是随机变量理论 ,其核心是利用变异函数获得研究对象的空间分布规律。同时 ,分别介绍了每个部分的具体方法 ,特别提到了新发展的多点地统计学方法。最后对地统计学的软件应用加以总结 。
Geostatistcs has been an important tool for spatial analysis recently, it has been applied many fields of natural science, such as geography, ecology, soil science and so on. The paper discusses the progress in the theory method of Geostatistics. The whole framework has been pointed out, including estimation, local uncertainty, stochastic simulation and multi point simulation. Especially the new methods, for example Sequential Gaussian Simulation, LU Simulation, P field simulation, Annealing Simulation are described. The paper analyzes the difference between multi point simulation with the traditional geostatistics methods. That is the breakthrough of two point method variogram to training image to describe the spatial structure of objects. Meanwhile, the paper makes a comment on the software of Geostatistics. The need of graphic user's interface, high quality image input and output, together with the absence of spatial analysis function, caused the combination of Geostatistics and GIS is an inevitable trend.
