摘　　要：为定量描述北方沙区生态承载状况,运用生态足迹模型计算了处于毛乌素沙地南缘的盐池县官滩村2006年的生态足迹与生态承载力。结果表明:官滩村人均生态足迹为2.011 9 hm2,人均生态承载力为1.656 8 hm2,人均生态赤字为0.355 1 hm2。其中,草地的供需矛盾突出,耕地的供需基本相当,林地和建筑用地供给充足。其中供给以耕地为主,需求以草地为主,供需结构不对称。生态赤字的存在,揭示了当前生态经济系统的不安全与不可持续性。In order to quantificationally evaluate ecological capacity in the north sandy land of China, ecological footprint model was used to calculate the ecological footprint （EF） and ecological capacity of Guantan village in Yanchi county of Ningxia ,which locates on the southern edge of Mu Us Desert, with the data in 2006. The result shows that the per capita EF of Guantan village is 2.011 9 hm^2 ,the per capita ecological capacity is 1. 656 8 hm^2 ,and the per capita ecological deficit is 0. 355 1 hm^2. The contradiction between the supply and demand of grassland is serious. The supply and demand of cultivated land is equal. There is sufficient supply for building land and woodland. The supply is mainly with cultivated land,while the demand mainly with grassland, the structure of supply and demand is dissymmetry. The existence of ecological deficit reveals that the current system of ecological and economic is insecurity and non-sustainable.
