Abstract: Resettlement work is a key constraint for many hydropower projects.However,few people carry out relatively quantitative study on the difficulty degree of resettlement work.This paper attempted to use the analytic hierarchy process(AHP)to describe the multi-dimensional characteristics of resettlement difficulty.The factors that should be taken into account in the quantitative evaluation of each index of resettlement difficulties were preliminarily discussed.Then,the proposed method was verified by practical projects.Three conclusions were obtained.(1)The resettlement difficulties were mainly reflected in the contradiction between human and land,long time span,difficult administrative coordination and demanding professional competence.(2) The hierarchical structure model can directly express the difficulties in the resettlement works.(3) The evaluation indexes system can be built on the base of hierarchical structure model.

Key words: hydropower resettlement; resettlement difficulty; hierarchical structure model; analytic hierarchy process;
