Research on Venture Judgment System of Dahuofang Drinking Water Source Protection Area

The risk assessment of drinking water source focused on quantitative assessment of contaminants detected in drinking water on human health risks, but the potential environmental risk assessment of source drinking water protection is rare research. Therefore, in this paper, expert systems and AHP were introduced into the conventional fuzzy comprehensive evaluation in order to improve the degree of judgments of decision-maker(s). Basing on fundamental principle of Analytic Hierarchy Process (AHP) and fuzzy comprehensive assessment, the indicator system is established for the source drinking water protection environmental risk. In addition, as a case study of Liaoning Province Dahuofang water-source protection, this model interprets the main risk in Hun River and helps the management distinguish the leading factors, select the appropriate preventive measures according to environmental risk model.
