Abstract:The water supply sustainability of Fengjiashan Reservoir was evaluated by means of the sustainable development concept and the theory and method of risk analysis. In the evaluation, five performance parameters such as reliability, resilience, vulnerability, standard deviation and maximum soil water deficit were selected as sustainability index(SI). According to four kinds of water users, namely life, industry, ecological environment and agriculture, proper sustainability indices for these users were established as well. Further a sustainability index was built for the group composed of those four kinds of water users. The results showed that the water supply sustainability by group(SG)is as low as 35% in current situation, especially the SI for agriculture is 29% only. If the agriculture water demand is reduced by 30%, then the reliability and SI for all the users are improved. Under this condition, the SI for agriculture is 40% and the SG for the reservoir is increased to as high as 45%. Therefore, whatever water saving measures should be taken in areas under irrigation to reduce agricultural water demand and enhance the agricultural sustainability and improve reservoir water supply sustai-nability as well as reduce the risk of water deficit, eventually promote the sustainable development of reservoir.
