克里格法在整理放射性水化学区调资料中的应用

本文对东北地区5706km~2范围内的放射件水化学详细区调资料用克里格法进行了电算处理,编制了1:20万铀水文地球化学图件。用克里格法对水中铀含量进行变异结构分析、确定异常结构(方向,大小),然后,再进行克里格估值。编图效果显著。

APPLICATION OF KRIGING METHOD IN DATA PROCESSING OF REGIONAL RADIOHYDROCHEMICAL SURVEY

The detailed data of regional radiohydrochemical survey within an area of 5706 km~2 in a certain place, Northeast China was processed by kriging method and U-hydrogeochemical map at 1:200,000 scale was compiled. Variation structure analysis was made of the uranium content in the water using kriging method and the abnormal structures(directions and sizes) were established, and then, kriging estimatcd value was made. The mapping effect seems to be obvious.
