摘要
土壤调查中常常需要解决曲面拟合问题，即根据有一定分布的有限个样本网络点数值（比如高程、地下水深度、土壤ｐＨ值等），计算研究区域中所有网格点的数值。这是一个经典的数学理论问题。本文将分形理论与数字滤波（数字信号处理）方法有机地结合起来，给出一种新型的曲面拟合计算方法，该算法可以适应研究区域中存在有隔离断裂曲面的复杂情况。
The
problem to imitate a camber often needs to be solved in soil survey. So-calledimitating camber
is to calculate the attribute data of whole grids in research areabased on a limited amount of
sample attribute data such as elevation data,underground water depth. soil pH.This is a
classical mathematical theory problem.This paper gives a new method to imitate camber,
which combines fractal theory withdigital filtering and is fit to process the complicated case with
a separating zone.
