Embodiment Construction

[0049] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0050] The embodiment of the present invention proposes a groundwater vulnerability assessment method, such as figure 1 shown, including:

[0051] 1. Selection of evaluation indicators

[0052]The accuracy of the evaluation results depends on the representativeness of the selected impact factors, while the accuracy of the evaluation results depends on the quantity and reliability of the data. According to the specific conditions of the irrigated area of ​​the target area, combined with some common factors in the vulnerability assessment, and referring to the groundwater vulnerability assessment results in other areas, especially arid areas, the influencing factors suitable for the groundwater vulnerability assessment in the study area were analyzed and selected.

[0053] (1) Groundwater depth

[0054] The depth of groundwater determines the depth of ...

Abstract

An embodiment of the invention provides a groundwater vulnerability assessment method, comprising the steps of selecting an assessment index for determining an assessment index affecting groundwater,wherein the assessment index is at least one of groundwater burial depth, net recharge amount, aquifer medium type, vadose zone medium type, topographic slope, soil salt content and aquifer hydraulicconductivity coefficient; determining the weight of the evaluation index, which is used for determining the influence degree of the evaluation index on the groundwater vulnerability by using the analytic hierarchy process to determine the weight of each evaluation index; the evaluation step being used for calculating the vulnerability index of the research area by superposing the evaluation indexes according to the weights through ArcGIS by using the evaluation indexes and the corresponding weights.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a groundwater vulnerability evaluation method. Background technique [0002] With the development of society, more and more fields are beginning to use data analysis and data processing technology. Water resource is an indispensable resource for human society, which is directly related to human survival and social stability. Many cities have exploited groundwater for urban water use, but many cities have the problem of overexploitation, resulting in damage to the natural circulation system of groundwater. Although there are some evaluation methods for groundwater vulnerability in the prior art, the stacked index method is a classic and commonly used method in the evaluation of groundwater vulnerability at present, and it is suitable for qualitative, semi-quantitative or quantitative index factor systems. Compared with other methods In comparison, it has the advantages o...
