摘　　要：利用生态足迹计算模型和分析方法,对陕西省榆林市2006年的生态足迹和生态承载力进行了研究和分析。结果表明:榆林市人均生态足迹需求为1.272 hm2,人均生态承载力为1.716hm2,人均生态盈余为0.444 hm2,属于较小程度上可持续发展状态。但是,近年来榆林市对自然资源的利用逐年增加,目前已接近或超出了自然生态系统的生态承载力范围,生态足迹与生态承载力之间的矛盾加剧,现有的发展模式是不可持续的,生态环境处于不安全状态。The ecological footprint and ecological capacity in Yulin in 2006 were studied. The results showed that the average personal ecological footprint demand was 1. 272 hm2 , and average personal ecological capacity was 1. 716 hm2 , with an ecological deficit of 0. 444 （hm2/person）. The research indicated that the utilization of natural resource in Yulin is increasing, which is beyond the capacity of the natural ecological system, the conflicts between ecological footprint and ecological capacity are intensifying, the present developing model is not sustainable, the ecological environment is at risk.
