Abstract:  Aiming at the problem of less comprehensive benefit evaluation and imperfect evaluation system of annual full mechanization of wheatcorn in hilly mountainous areas of Shandong, a comprehensive benefit evaluation system was constructed based on the analytic hierarchy process and the expert evaluation method to protect the agricultural ecological environment and improve agricultural economic benefits, ecological benefits and social benefits of the annual full mechanization technology model. The system includes 3 level 1 indicators of economic benefit, ecological benefit and social benefit, sets 7 level 2 indicators of economic return, resource utilization, soil protection, social contribution and mechanization rate, and determines 13 level 3 indicators of net income per unit area, annual per capita income and so on. It was carried out the determination of the weights and scores of the comprehensive benefit indicators, and used a typical cooperative in the hilly mountains of Shandong Province as an example for verification. The results showed that the weighting ratio of the primary indicators of economic, ecological and social benefits was 6∶2∶2, and their full marks were 60, 20 and 20; the weighting of the secondary indicator of economic benefits was 1, and its full marks were 60; the weighting ratio of the secondary indicator of ecological benefits between resource use and land protection was 3∶1, and its full marks were 15 and 5; the weighting ratio between the secondary indicators of social contribution, mechanization rate, disaster mitigation and extension rate is about 6∶3∶6∶5, and its full marks are 6, 3, 6 and 5. The score of Yaojia Cooperative in Wendeng District, Shandong Province, was calculated to be 70, and diagnostic comments were given to the cooperatives score. The study is a guide to the production and development of agricultural planting cooperatives in the hilly mountainous areas of Shandong Province, and also provides a useful reference for the local government.
