Grey relational model based on AHP weight for evaluating groundwater resources carrying capacity of irrigation district

Abstract

In order to evaluate groundwater resources carrying capacity of irrigation district scientifically, grey relational analysis model is applied to evaluate groundwater resources carrying capacity. In this model, AHP theory is applied to determine the evaluated index weight. Then the evaluation model is applied to an irrigation district. The result shows that it is coherent to the actual condition. It validates the evaluation model is simple and feasible in synthetic evaluating groundwater resources carrying capacity. The result can offer a valuable reference for sustainable development of irrigation district.
