摘要

There are not more studies on whether the improved set pair analysis(SPA) could apply to risk assessment of shallow groundwater pollution. In order to make the most of this method, this paper firstly puts forward the pollution risk analysis model according to the pollution process and constructs a risk assessment system of shallow groundwater pollution even associates it with unascertained measure theory and analytic hierarchy process. The analytic hierarchy process is used to determine the weight of each layer; The measure function decides the membership degree of the index layer for calculating the unascertained evaluation matrix of the system layer; The connection number of set pair analysis is linked to the level of pollution risk assessment. The evaluation example is used to identify the feasibility about the method of the improved set pair analysis, and the result is entirely feasible. Moreover, this improved approach shows the actual pollution risk situation.
