Abstract

The invention discloses an underground water chemical partitioning method based on Arcgis. The underground water chemical partitioning method comprises the following steps: collecting seven basic iondata of underground water in a target area all the year round; based on the seven ion data, determining the water chemical type by using a Schcav classification method; and establishing a Thiessen polygon by utilizing Arcgis neighborhood analysis, and carrying out fusion analysis on the Thiessen polygons with the same hydrochemical type to obtain a hydrochemical partition. According to the underground water chemical partitioning method based on Arcgis, seven ion data and latitude and longitude coordinates are used for carrying out hydrochemical partitioning, the hydrochemical partitioning result is reasonable, certain novelty is achieved, operation is easy, practical application is easy, and a new method and a new idea are provided for underground water chemical partitioning.

Description

technical field [0001] The invention relates to the technical field of groundwater chemical zoning, in particular to an Arcgis-based groundwater chemical zoning method. Background technique [0002] Groundwater chemical zoning is a very critical and fundamental process in hydrogeological work. In the process of studying groundwater chemistry, most of them are analytical methods and numerical methods. Most of these methods are relatively cumbersome to operate and consider complicated factors. The present invention provides a simple and qualitative water chemical partitioning method for this problem. Contents of the invention [0003] 1. Purpose of the present invention [0004] In view of this, the present invention provides a qualitative chemical zoning method aimed at the deficiency of the groundwater chemical zoning method. [0005] 2. Technical scheme of the present invention [0006] In order to achieve the above object, a field of the present invention, specificall...
