- 摘要:
- 通过统计分析方法确认颗分试验法得到的非饱和带平均粒径和定性测定法得到的平均粒径可作为协同区域化变量的基础上，通过将颗分试验平均粒径数据作为主变量，利用与它有协同区域化关系的定性测定法获取的非饱和带大量平均粒径数据用协同克立格法对研究区非饱和带平均粒径进行了大尺度估值。用估值结果对非饱和带平均粒径变异性进行了分析评价，给出了平均粒径空间变异分区图。
- Abstract:
- This paper is based on the identification by that the average grain diameter by size grading approach and by qualitative determination approach can work as co-regionalized variable, then took more average grain diameter information by qualitative determination approach and let them as main variables to estimate average grain diameter of rock formation of unsaturated zone in large scale by co-kriging approach. The variability of average grain diameter of rock formation of unsaturated zone has been analyzed by those estimated information and the spatial variability map for average grain diameter of rock formation of unsaturated zoon has been given too. This study not only got accuracy results but also provide a simple approach for getting the spatial variability of average grain diameter of rock formation of unsaturated zone.
