| 摘 要： | 基于传统生态足迹模型改进的“本地生态足迹”模型，引入热值概念，以新疆土地平均生产力为核算标准，调整乌鲁木齐市生态足迹模型中的3大核心参数，测算了乌鲁木齐市2000-2010年各类型土地实际发生的生态足迹、生态承载力和生态盈余。结果表明：乌鲁木齐市人均生态足迹从2000年的每人5.63 hm2增加到2010年的24.0 hm2，而人均生态承载力从2000年的0.84 hm2下降到2010年的0.57 hm2，人均生态赤字从2000年的4.54 hm2增加到2010年的23.04 hm2。2000年以来，除了牧草地以外，其他类型土地均是生态赤字，建设用地是乌鲁木齐市生态足迹和生态赤字的最大贡献者，2010年对生态赤字的贡献达到了93.04%。牧草地则是生态承载力的最大供给者，但自2004年以来其生态盈余呈不断下降趋势，表明乌鲁木齐市土地生态系统处于超负荷利用状态。应通过减少人口压力、提高耕地、牧草地等的平均生产力，大力实施循环经济等措施来减少乌鲁木齐市生态足迹，增加生态承载力，以实现土地的可持续利用。

| Abstract: | In this paper, the Local Ecological Footprint Model was used to calculate the actual ecological footprint, ecological capacity and ecological surplus or deficit in Urumqi during the period from 2000 to 2010. Three important parameters were adjusted based on the average productivity of land in Xinjiang. The results show that the per capita ecological footprint was increased from 5.63 hm2 in 1998 to 24.0 hm2 in 2010, the ecological capacity was decreased from 0.84 hm2 to 0.57 hm2, and the ecological deficit was increased from 4.54 hm2 to 23.04 hm2 The contribution of grasslands to the ecological capacity in Urumqi was the highest, an ecological surplus of grasslands was maintained since 2000, and an ecological deficit of other land types occurred. Ecological deficit of construction land was increased quickly during the period from 2000 to 2010, and the contribution of construction land was up to 93.04% in 2010 because of the population growth and the increase of energy consumption. The land ecosystem development in Urumqi was unsustainable, so some effective measures should be taken so as to reduce the pressure of population growth, improve the average productivity of land, change the mode of economic growth, and develop the recycling economy in Urumqi. |
