| 摘 要： | 资源勘查过程是一个不断获取新的资源信息过程,选择最优勘查网度是降低勘查成本、加快勘查速度的关键之一,地质统计学方法在勘查网度研究方面有很大的优越性.本文选取中太平洋SA海山作为研究对象,利用地质统计学法,建立SA海山结壳厚度的理论变差函数模型.根据估计方差是勘探网度和网型的函数这一原理方法,分析认为当前的勘查网度无法控制该海山钻结壳的分布,还需加密调查取样,并模拟得出了最优勘查网度,为大洋矿产勘查航次设计提供参考. |

| Abstract: | Resource exploratory process is a process for continuously obtaining information about new resources.It is one of the key problems for reducing exploratory cost and accelerating exploratory velocity for choosing optimal exploratory grid.Geostatistics data have many advantages for evaluatiing exploratory grid.The geostatistics data were applied to analyzing the geological features of the SA seamount in the central Pacific.The theoretical variogram model of cobalt crust thickness on the SA seamount was established with the Ordinary Kriging method.Current exploratory grid could not control the distribution of cobalt crust on the seamount according to the variance laws of thickness being the function of exploratory grid and grid type.It is necessary to get more samples for investigation.The optimal exploratory grid was determined to provide references for designing of various voyages for ocean resource exploratory investigations. |
