| 摘 要： | 多时段泛克立格模型是研究水文随机函数最优估计和空间预报的比较优越的方法。针对水文数据在时间上缺乏而空间上富足的特点,为了较好地解决小流域或局部区域内少站点情况下水文变量的最优估计问题,本文用多时段泛克立格模型对滦河内蒙古段闪电河流域各测站年降水量缺测资料进行了插补并在流域内进行了空间插值预报,结果表明插值预报精度较高,所得结论比较可信。

| Abstract: | The universal kriging spatial estimation with multiple time period is one of the best methods in studying optimal estimation and spatial forecasting of hydraulic random function.The characteristic of hydraulic data is limited in time while plentiful in space,in order to solve the problem of optimal estimation in small drainage area with few stations,the method is used in this paper to interpolate missed annual precipitation data of each station and to forecast data in space in Shandian River drainage area.T... |
