摘　　要：基于生态足迹原理,对咸阳市1999—2006年生态足迹与生态安全进行了定量研究。结果表明,咸阳市人均生态足迹逐年增加,人均生态承载力逐年下降,人均生态赤字、生态压力不断增加,表明该市的发展模式是不可持续的,其生态环境具有不安全性,社会经济发展与生态环境的协调性很差。万元GDP生态足迹虽呈逐年下降趋势,但仍大于1999年的全国水平,说明咸阳市的资源利用方式仍处于消耗型、粗放型阶段。并针对以上问题提出了咸阳市可持续发展的合理途径。Based on the principle of ecological footprint, the ecological footprint and ecological safety of Xian- yang City from 1999 to 2006 were quantitatively analyzed. Results showed that the ecological footprint per capita gradually increased year by year, the ecological capacity per capita gradually decreased, the ecological deficit per capita and ecological tension continuously increased, and the social economic development was not coordinated with ecological environment, which indicate that the development of the city is not sustainable and its ecological environment is not safe. Though the ecological footprint of 10 thousands Yuan GDP had a dropping tendency, it was still greater than the averaged national level in 1999, which shows that the re- source use of the city was still an resource exhausting and extensive management pattern. Finally, by consid- ering these facts, some available ways for the sustainable development of Xianyang City were brought up.
