Abstract: Aiming at the regional soil and water loss problems caused by the water diversion project from the Yellow River in Jiaodong agricultural irrigation area, the evaluation method of soil and water conservation quality of the water diversion project from the Yellow River in Jiaodong agricultural irrigation area was put forward, which provided scientific basis for the relevant departments to formulate soil and water conservation rectification measures. Due to the significant relativity between soil and water conservation and soil erosion, the current situation of soil and water conservation in the area involved in the project was analyzed from these two aspects. Based on the close correlation among soil erosion, soil and water conservation and soil quality, the soil and water conservation quality was described by soil quality, and the evaluation model of soil and water conservation quality was constructed. According to different evaluation index weights and membership degrees, the soil quality index scores of different regions in Jiaodong agricultural irrigation area were determined, and the evaluation results of soil and water conservation quality were obtained. The results showed that the quality of soil and water conservation in Binzhou city and Yantai city were at a low level, and the quality of soil and water conservation in Weifang city was at a lower middle level, and according to the current situation of low quality of soil and water conservation, this study put forward some strategies to improve the quality of soil and water conservation.

Key words: agricultural irrigation area, water diversion project from the Yellow River, water and soil conservation, quality assessment, soil erosion, soil quality
