一个评价索引模型被建立到 evaulate 通过分析层次过程的三峡的水库迁居的利益。完全， 43 指示物被选择在移植社区的经济、社会、生态的环境方面上估计移植的影响，与年的指示物的数据 1992 ， 1998 ， 2002 它代表了 premigration 的时期，第一阶段迁居的结束和第二阶段迁居的结束分别地。评估矩阵是足够地一致的，与一个一致性比率 CR 平等者到 0.086 3。评价在一年 2004 为经济分系统生产了利益价值大与在一年 1992 使价值增加两倍比，在水库区域显示显著经济生长。为社会分系统的常常增加的价值反映稳定的社会状况。在为一年 1998 的生态的分系统的评价结果有细微衰落，它暗示 enviromental 保存在那个时期期间被给不够的重要性。总体上，迁居工程的实现对水库区域有利，作为在 2002 在 1992 ～ 68.81% 从 42.22% 由稳定地增加的全面评估价值证实了。然而，仍然有许多空间从现状改善到目标标准。

英文摘要：

An assessment index model was established to evaulate the benefit of the Three-Gorges Reservoir migration through the analytical hierarchy process. Totally 43 indicators were selected to assess the impact of migration on the economic, social and ecological environmental aspects of the migration communities, with the data of the indicators of the years 1992, 1998, 2002 which represented the period of premigration, the end of the first phase migration and the end of the second phase migration, respectively. The evaluation matrix is sufficiently consistent, with a consistency ratio CR equal to 0.086 3. The assessment turned out a benefit value for the economic subsystem in the year 2004 larger than triple the value in the year 1992, indicating a remarkable economic growth in the Reservoir area. The constantly increasing value for the social subsystem reflects the stable social situations. There is a slight decline in the assessment outcome of the ecological subsystem for the year 1998, which implies enviromental conservation was given insufficient importance during that period. On the whole, the implementation of the migration project is favorable to the Reservoir region, as confirmed by the stably increasing overall evaluation value from 42.22% in 1992 to 68.81% in 2002. However, there is still much room to improve from the status quo to the target criteria.
