Abstract:: The standardized runoff index (SRI) of river runoff was selected as drought evaluation index for the description of drought severity grade in Yarkand River Basin. Water shortage in Yarkand River Basin was calculated at the different drought grades. An optimal assessment model was developed to aim at comprehensive benefit satisfaction index with respect to different increasing income and reducing expenditure measures. Based on the model, six optimal emergency deployment plans of water resources that well considered the optimization of the overall benefit including economic, environmental and social demand were assessed in Yarkand River Basin. The results show that water shortage rate can be reduced from 20.68% to 6.23% during very serious drought periods, the sixth emergency plan can significantly reduce water shortage situation and effectively ease the contradiction of water supply and demand in Yarkand River basin.
