中文摘要：

生态的脚印概念和它的计算模型为社会、经济的开发的持续水平的测量是有用的。三个峡水库区域(TGRA ) 的生态的安全状况在这研究用这个概念被评估。三座峡水库的构造在生态学和 TGRA 的移民地位导致了变化。生态的脚印方法是一个重要工具学习地区性的生态的安全。我们的结果建议了那，由排除为生物多样性保存(12% 全部的土地) 的区域，生态的脚印人均是 0.57895 哈，它在 TGRA 超过了生态的带能力。全部的生态的赤字被发现是 11,522,193.34 哈，为 95.02% 生态的带能力的财务。这些调查结果建议 TGRA 的生态的安全不好。以便补偿生态的赤字，从另外的区域介绍自然资源是必要的。

英文摘要：

The ecological footprint concept and its calculation models are useful for the measurement of the sustainable level of social and economic development.The ecological security situation of the Three Gorges Reservoir Area（TGRA） was evaluated using this concept in this study.The construction of the Three Gorges Reservoir has led to the change in the ecology and immigration status of TGRA.The ecological footprint method is an important means to study the regional ecological security.Our results suggested that,by excluding the areas for biodiversity conservation（12% of the total land）,the ecological footprint per capita was 0.57895 ha,which exceeded the ecological carrying capacity in TGRA.The total ecological deficit was found to be 11,522,193.34 ha,accounting for 95.02% of the ecological carrying capacity.These findings suggested that the ecological security of TGRA was not good.In order to compensate for the ecological deficit,it was essential to introduce natural resources from other regions.
