1. In the course of simulation , the model has no relation to kriging method , it only use the matrix information of covariance or variogram . so it can conquer the disadvantage that kriging method smooth the geological parameters , and fit the numerical simulation for the geological parameters such as permeability whose values change quickly and largely . it can estimate the distribution of extra high value and extra low value of permeability more perfectly and more accurately , which the geologist and field engineer mainly care for
   在模拟过程中，克里金方法本身不与模型发生关系，它仅利用协方差或变异函数这个矩信息，这样就克服了克里金方法对参数的光滑效应，使得其适用于象渗透率这样变化幅度较大的地质参数的数值模拟，对地质专家和油藏工程师最关心的渗透率的特高值或特低值的分布情况预测更为全面、准确。
2. The analyst of isotropy indicated that the sample spots of 12 soil nutrient contents ( except total nitrogen ) were correlated in given spatial range . the semi - variogram values increased when the distances were enlarged , and nugget lied in , which meant the existence of spatial variability structure , and sample spots were correlated in the 50 - meter of sampling distance
   各向同性分析的结果表明： 12种(除全氮)土壤养分在一定的范围内观测值之间存在着空间相关性，变异函数( h )随间距增大而增大，且有基台值，说明存在空间变异结构特征，在50m的采样间距内存在空间相关性。
3. This paper combines the critical rainfall in the typical areas of yunnan province , and carries on the analysis to the critical rainfall situation , and carries on a research to the variety regulation of the critical rainfall of the mountain flood disasters in yunnan province by the application of spacial variogram theory , and the kringing of spacial gridding methods , the inverse distance to a power method , the radial basis function method , and then draws up each isoline maps
   采用空间变异理论，应用克里金空间插值分析法、反距离加权插值法、径向基函数插值法对云南省山洪灾害典型区的临界雨量的情况进行对比分析，对其变化规律进行研究，并绘制相应等值线图。
4. The results show that the maximum likelihood classification based on variogram texture and spectral bands can perfectly define the grades of beach sandy land and inner desertification , and the maximal classification precision comes up to 92 . 4 % , which proves that geostatistical texture is effective in the application of desertification monitoring
   结果表明，运用变异函数纹理结合光谱波段的最大似然分类方法能够很好地界定海滩沙地和内陆荒漠地的等级，最高分类精度达到92 . 4 % ，证明了基于地质统计学的影像纹理在实现该地区遥感荒漠化监测方面的有效性。
