| 摘 要： | 半变异函数的获取既有人为主观求取法,又有运用数学工具客观求取法,但是后者是今后的主要趋势。笔者在前人工作的基础上,归纳出多项式回归法、线性规划法和目标规划法三种求解半变异函数的成熟方法,以及非线性回归理论直接求解法、进化计算和积分面积三种新兴方法,并总结出各种方法的优缺点。最后概括出计算权重的两种方法。

| Abstract: | Subjective solving methods and solving methods using mathematical tools are the methods of acquiring semi-variogram,with the latter of which being the main trend in the future.Based on the summary of the early studies,this paper summarizes the three conventional methods of solving semi-variogram which are polynomial regression method,linear programming method and goal programming method,put forwards the three newly developed methods of solving semi-variogram which are non-linear regression direct solving method,evolutionary computation method and area integration method,and summarizes the advantages and shortcomings of the above methods.In the end,it gives out two methods of calculating the weighting. |
