【 摘 要 】

The water resources system is composed of water resource utilization system, water environmental quality system and water disaster system. This paper analyzes the process of vulnerability formation of water resources utilization system from the aspects of natural endowment of water resources, development and utilization of water resources and water use efficiency. The vulnerability model of water resources utilization system was constructed, and the research on vulnerability level was carried out. Based on the trapezoidal fuzzy number of the difference coefficient, an evaluation method based on the number of trapezoidal fuzzy numbers is proposed. The application results show that the principle of the method is clear and the calculation process is simple. It avoids the error that may exist when the value of the component coefficient has a wide peak distribution, and can more accurately reflect the objective actual situation.
