Groundwater Vulnerability Fuzzy Evaluation in Qujing Basin

Abstract:

As the Qujing citys industrial development, how to use and protect groundwater is the primary problem of urban development because of the non-uniformity distribution of groundwater. This paper establishes a two-story DRASTIC fuzzy evaluation model using analytical hierarchy process, by Qujing basin groundwater survey and data analysis. The model was applied to evaluate the groundwater vulnerability of Qujing basin and the east and west sides of the mountain with the consideration of depth to the water table, net recharge, aquifer material, soil type, topography, impact of vadose zone and hydraulic conductivity of aquifer with the help of monitoring data. The research results show that the Qujing basin is of high vulnerability, we should pay attention to the protection of groundwater environment in the use of groundwater. At the same time show that the model is more sensitivity for evaluating and much simple for calculating. This method is better to reflect the groundwater vulnerability spatial continuity, and further enriched the groundwater vulnerability methods.
