摘要
将空间域上的克立金方法延伸到时空域中,得出当时间信息量大于空间信息量时区域化变量的无偏最优估计形式,进而给出时间域上克立金的估计形式,最后利用该方法对某湿地近几年水体中BOD-DO的未来的趋势进行了预测,实例说明该方法是一种比较稳健的预测方法.
Taking Kriging method in space domain develop to space-time domain, it can be obtained best estimation of regionalized variables by space-time information and best estimation of spatial components in the case of time information larger than space information. This paper studies the basic theories of statistics method of multivariate information in space-time domain. Based on the statistics of BOD and DO of recent years using the method of multivariate information in a pure time area to forecast changing trend of BOD-DO of some wetland in the last.
