文章首先介绍了利用克立格插值方法建立地下水数字水位模型的原理,然后在此模型的基础上,按照地下水降落漏斗的基本定义,提出了一种自动化提取降落漏斗的算法。最后通过一个算例的实现,对比地下水等水位线,证明了根据该算法提取的结果较准确地反映了地下水降落漏斗的水文地质含义,科学、客观地表达了水位下降区的空间形态,是数字地下水建设的有益探索。
Firstly, the paper introduces the principle of using Kriging interpolation method to establish groundwater digital water level model. Based on this model, an algorithm of automatic extraction of landing funnel is proposed according to the basic definition of groundwater dropping funnel. At last, an example is given to compare the water level of groundwater. It is proved that the results extracted by this algorithm can accurately reflect the hydrogeological meaning of groundwater dropping funnel, and scientifically and objectively express the spatial form of water level descending zone. Beneficial exploration of groundwater construction.
