动态聚类法用于地下水位动态分类

DYNAMIC CLUSTER METHOD APPLIED TO THE CLASSIFICATION OF THE GROUNDWATER LEVEL REGIME

在研究地下水位动态观测网时,首先必须解决地下水位动态分类问题。本文以陕西两华(即华县和华阴县)地区地下水位动态观测网为例,将数理统计学中的动态聚类法应用于地下水位动态分类。通过计算,可将该区的地下水位动态分为四类,它们与实际的水文地质条件相符合。计算表明,对于大样本的地下水位动态,动态聚类法具有明显的优点,其主要优点是占用计算机内存比较少。

The first work is to classify the groundwater levet regime when studying the ground-water level regime monitoring network. The dynamic cluster method is introduced in this paper to study the classification of the groundwater level regime.The groundwater level regime at Huayin and Huaxian, Shaanxi province in China is taken as an example to be studied with this method. Having computed the example with this method, the groundwater levet regime above the area is classified into four types. The result is in agreement with the real hydrogeological conditions. It is shown that there is definite advantage with the method, especially, occupying fewer internal space of computation.
