Abstract: | There are a lot of key qualitative variables in factors affecting groundwater vulnerability. The processing of qualitative variables of the existing superimposed index method generally relies on experience, so the results are normally subjective. Quantitative theory can handle qualitative variables quantitatively, achieve the unity of quantitative and qualitative indicators, highlight the decisive role of the main factors and reflect the actual situation more objectively. We took Yulin City as the research area to verify the feasibility and applicability of quantitative theory III, which is used for the quantitative evaluation of groundwater vulnerability. The results show that it has obvious advantage in the screening of indicators and the groundwater vulnerability partition, so it can be used as a quantitative calculation method of groundwater vulnerability assessment |
