中文摘要：
借助生态足迹模型和收集的统计年鉴数据,分析了高台县2005—2010年的耕地生态足迹.结果表明,研究时段内人均耕地生态足迹与人均生态承载力均呈现波动变化趋势,总体上两者均呈增加趋势;人均耕地生态赤字经历了3个变化阶段（上升→下降→上升）,但总体上呈轻微下降趋势;生态超载指数经历了＂先增后减再升＂的变化阶段,整体呈下降趋势,而其数据值依然较大且为正值,说明高台县耕地负荷利用程度虽有所缓和,但仍处于超负荷利用状态.针对研究区的生态赤字问题,从减少耕地生态足迹和增强耕地生态承载力两方面,提出了相关对策.
英文摘要：
The ecological footprint model and some statistical data were applied to analyze the cultivated land ecological footprint in Gaotai County during 2005—2010.The results indicate that both the cultivated land ecological footprint per capita and the cultivated land ecological carrying capacity per capita in Gaotai County are in 3 change stages（increasing→ failing→ increasing）,and they generally show an increasing trend.The cultivated land ecological deficit is in 3 change stages（increasing→ failing→ increasing）,and it generally show an failing trend.In the analysis period,the ecological overshoot index of cultivated land is in 3 change stages（increasing→ failing→ increasing）.The data of the ecological overshoot index of cultivated land in Gaotai County during 2005—2010 show that the cultivated land ecological carrying capacity is still in the situation of overload use.For the ecological deficit,some countermeasures were proposed from reducing the ecological footprint of cultivated land and enhancing the ecological carrying capacity of cultivated land.
