Abstract: To promote the comprehensive land consolidation results of specific land consolidation project, the key is to design different schemes and select the best one. In this paper, the project of land consolidation for Shuangtong Village in Qingyang city of Gansu Province, China, was chosen as an example. Four schemas were designed for the land consolidation project for different perspectives: schema equally emphasizing on ecology and economy, schema dominated by economic benefits, schema matched with infrastructure and schema guaranteeing people’s livelihood. Two indicators, total investment and labor input, were chosen according to the items, the investment level and efficiency measurement of the project. Another five indicators were chosen according to yield to set up indicator system, which are the yield added value per unit area, the static return on investment return, the rate of increased farmland, the increment of annual net income per capita and the increment of vegetation coverage. With the two groups of indicators, a DEA model with AHP constraint cone was created and then the four schemes were compared. The values of the four schemes from No. 1 to No. 4 were as follows: 1.000 0, 0.864 5, 0.652 7, 0.963 8, suggesting the first scheme (the schema equally emphasizing on ecology and economy) was the best one, followed by the fourth scheme (the schema guaranteeing people’s livelihood), then the second scheme（dominated by economic benefits）and finally the third scheme (schema matched with infrastructure). The study showed that the DEA model could combine the traditional objective analysis of input and output data with the subjective preference of decision-maker and adopt the advantages of AHP and DEA could produce more objective and accurate evaluation results than that only by AHP or DEA. The study also demonstrated that both ecological and economic benefits should be considered to promote the result of land consolidation. People’s wish to improve livelihood should also be considered when designing land project scheme. The study provided scientific methods for comparing and selecting the design scheme of land consolidation project, put forward suggestion for the main perspective of designing land consolidation plans, and provided preference for reasonable evaluation and conduction of land consolidation.
