The more scientific land remediation comprehensive benefit evaluation is of great significance to land remediation strategic deployment. Taking land remediation in Suizhou city of Hubei Province as an example,we try to make beneficial exploration for land remediation benefit evaluation research. The combined weighting method was adopted to improve the accuracy and reliability of weight, and the comprehensive benefit of land remediation in Suizhou was analyzed and evaluated by using the grey relational analysis. The benefit of land consolidation was significant in Suizhou City, but significant difference among counties. The correlation degree of economic, social and ecological benefits of land consolidation in Suixian County were 0.300 9, 0.276 3 and 0.256 1, respectively. The correlation degree of economic, social and ecological benefits of land consolidation in Guangshui city were 0.289 4, 0.253 1 and 0.249 2, respectively. The correlation degree of single economic, social and ecological benefits of land consolidation in Zengdu District was 0.270 0, 0.248 4 and 0.269 4, respectively. The correlation degree of comprehensive benefits in Suixian, Guangshui and Zengdu districts were 0.281 4, 0.266 6 and 0.261 8, respectively. On the whole, the ecological benefits of land remediation were relatively poor. Except that the ecological benefits of the former capital area were slightly higher than the social benefits, the ecological benefits of the other two places lagged behind with the economic and social benefits. The CW-GRAP model takes into account the fuzzy characteristics of land improvement benefit evaluation, and is a feasible research method, which can provide references for the study of evaluation on land improvement benefit in northwest Hubei Province.
