摘要
本文将随机水文学理论和地质数学理论有机地结合在一起 ,提出了用时空随机函数观点去分析水文数据的多时段空间剩余协克立格模型。该模型仅利用有限站的多变量水文时间序列数据即可建立起反映每一时段多变量时空相关特征的变差函数模型 ,从而能够在局部范围内对多个水文变量进行最优估计或外推预测。
A multi-period spatial residual Cokriging model combining Stochastic Hydrology with Geomathematics,was used to analysis hydrology data with spatial and temporal random function. The model can take optimal estimation and extrapolating forecast to more hydrology variables located at local area in terms of variogram model which has been obtained from multivariate hydrology time series at limited station describing multivariate time-space correlative properties at one time period.
