Due to all indicators of large and medium biogas project comprehensive evaluation have fuzziness and uncertainty,so it brings some difficulties to biogas project comprehensive evaluation, in order to perfect evaluation method of biogas project, utilize the method of combining AHP with entropy weight to calculate comprehensive weight, build a comprehensive evaluation index system, including four aspects altogether twenty-one evaluation indicators of economy, society, environment and technology, and build a large and medium biogas project fuzzy comprehensive evaluation model basing on AHP and entropy weight. Thus it realizes evaluation indicator and evaluation method’ scientificity and also achieve convenient and practical purpose. Finally, take some large and medium biogas projects as examples and carry on comprehensive evaluation’s empirical research, the evaluation result is objective and realistic.
