Embodiment 1

[0045] see figure 1 As shown, the testing method of the groundwater vulnerability assessment result that the embodiment of the present invention provides, comprises:

[0046] S11. Based on the groundwater vulnerability assessment results obtained by the groundwater vulnerability assessment method, determine the vulnerability zone where the highest concentration of pollutants is located and the vulnerability zone where the lowest concentration is located; wherein, the groundwater vulnerability assessment results include: groundwater vulnerability index and groundwater vulnerability classification results, the pollutants mentioned are certain types of characteristic pollutants;

[0047] S12. According to the results of groundwater vulnerability classification, determine the average concentration of pollutants corresponding to each level of groundwater vulnerability;

[0048] S13. Calculating the degree of correlation between the pollutant concentration and the groundwater vulne...

Abstract

The invention provides a ground water vulnerability evaluation result check method and can check validity and reliability of a ground water vulnerability evaluation result. The method comprises steps that a), a vulnerability zone with highest concentration of pollutant and a vulnerability zone with lowest concentration are determined; b), an average pollutant concentration of each ground water vulnerability grade is determined; c), a correlation degree between pollutant concentration and a ground water vulnerability index is calculated; d), through variance statistics F check, a statistical magnitude F value is determined; and e), the ground water pollutant concentration and the ground water vulnerability evaluation result are divided into same-quantity grades, an absolute value of a grade difference value is calculated; according to the a), b), c), d) and e) steps, comprehensive comparison and analysis on the ground water vulnerability evaluation result is carried out, and an evaluation result is reliable. The method is advantaged in that the method is applicable to the ground water environment science and ground water pollution risk management field.

Description

technical field [0001] The invention relates to the fields of groundwater environmental science and groundwater pollution risk management, in particular to a test method for groundwater vulnerability evaluation results. Background technique [0002] In recent years, groundwater vulnerability assessment is the main measure to prevent groundwater pollution. Groundwater areas with different vulnerability levels are delineated by distinguishing the sensitivity of groundwater to pollution in different regions. Pollution prevention and control programs, regional land use and development policy formulation, urban waste dump site selection and groundwater quality monitoring network layout all have certain theoretical guiding significance. [0003] The accuracy of groundwater vulnerability assessment results is not only a yardstick to measure the accuracy of the assessment object and assessment method, but also the most concerned issue for decision makers. Currently, there is no dir...
