Xianghuang Banner is located in the semi-arid pastoral area, and the water supply of some areas can not meet the needs of economicdevelopment, and the water resources transfer project was urged to plan based on the evaluation of water resources carrying capacity. According tothe characteristics of water resources utilization, an evaluation indexes system was constructed based on the projection pursuit model. The resultsshow that: (1) The water resources carrying capacity of Xianghuang Banner is weak, and Wenggongwula Sumu is better than Xinbaolage Town,which is the weakest area of water resources carring capacity. (2) The degree of groundwater development, population density, water resources percapita, water consumption per unit of GDP and ecological water consumption rate have the great influence on water carrying capacity. Based onthe evaluation results, the water resources transfer project was made for water transfer from Wenggongwula Sumu to Xinbaolage Town, which canhelp to relieve water supply stress of both areas. The results can provide the scientific basis of water resources regulation plan for XianghuangBanner, and also provide reference for water resources management in other similar areas.
