摘　　要：利用生态足迹分析方法,从能值理论角度对石河子绿洲1990-2010年的生态足迹和生态承载力进行计算和动态分析研究。结果表明:该地区人均生态足迹从1990年的2.1309hm2增至2010年4.2368hm2,增加了98.83%;人均生态承载力、人均生态足迹赤字呈逐年上升的趋势,从1990年的0.7725hm2增加至2010年的2.7190hm2。说明石河子绿洲目前已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,生态系统处于不安全状态。最后提出了解决这一问题的有关对策。The ecological footprint and ecological capacity of Shihezi during 1990 to 2010 were studied, and the forecast model was obtained. The results showed that the per capita ecological footprint increased by 98.83% ,from 2. 1309 hm2 in 1990 to 4. 2368 hm2 in 2010;the per capita ecological deficit gradually increased from 0. 7725 hm2 in 1990 to 2. 7190 hm2 in 2010. This research indicates that the utilization of natural resources of Shihezi oasis is beyond the capacity of the natural ecological system, the conflicts between the ecological footprint and ecological capacity are going up, the present developing model is not sustainable,and the ecological system is at risk. This paper puts forward some countermeasures from the aspects of population, land use and so on.
