摘要：In accordance with the characteristics of water source, this study analysed its influencing factors. Pressure-state-response (PSR) model for drinking water source security was proposed. The security evaluation system with three levels was established based on the model; the indicator weights were determined by analytic hierarchy process. The five-grade assessment standard was adopted, and according to the choice principle of the indicator, 14 indicators were selected. Each grade range of every indicator was determined, and fuzzy comprehensive evaluation method applied to evaluate the security grade of criterion layer and the whole system. The evaluation results indicated that drinking water source security grade of Dahuofang reservoir was “high” level, but very close to the “medium” level. The corresponding protective measures for water source were put forward.
