In order to quantitatively assess the structure, function and benefit of biogas eco-agricultural models, based on the studies of eco-agricultural model evaluation index system, 17 indicators were selected to construct a comprehensive evaluation index system of biogas eco-agricultural model, multilevel averaging weight method was used to confirm the weights of indices, the assessment model was constructed by comprehensive evaluation method. We also verified the model with the data of two typical biogas eco-agricultural models (Longxian "biogas digester-toilet-stable-vegetables, fruits, food)" courtyard ecological agriculture model and Qianyang County "mulberry tree-silkworm-agaricus bisporus-stable-biogas digester" eco-agricultural model) in Baoji City, Shanxi Province, and the assessment results were consistent with the actual situation.It is showed that the evaluation index system and the model have adaptability.
