利用地下水水位资料推求水文地质参数

INVERSION OF HYDROGEOLOGICAL PARAMETERS FROM SURVEYED GROUNDWATER LEVEL

依据模糊集合理论,提出了反求水文地质参数的一种新方法,即用模糊模式识别评价计算水位与观测水位的拟合程度,依模糊ISODATA聚类法的原理建立目标函数,以相应的聚类中心作为要求的水文地质参数。

Based on the fuzzy set theory, a new method is put forward in this paper for inversion of hydrogeological parameters. By use of the fuzzy pattern recognization, we have succeeded in inevaluating the degree of conformity of the calculated water level to the practical water level. Referring to the fuzzy ISODATA cluster, the object function is set up and the elements of the cluster centres are regarded as the hydrogeological parameters.
