Abstract Ecological materials of natural and artificial material applied on the ecological engineering in internal currently,usually lack of evaluation for applicative conditions.Hence,this study carried on the whole research and identifications to draft the materials of ecological engineering.The evaluation models of applied materials for ecological engineering were proposed.The quantitative score were obtained by expert's person evaluation.Three models were proposed to quantify the effects of applied materials on the ecological environment.The statistical procedures were adopted to compare the performance of these materials for ecological engineering.The results indicated that the comparison of applied materials can be treated by quantitative analysis.For the further analysis,more evaluated data from expert's experience need to be collected then the bias of person subject can be reduced.In addition to reach the benefits in the respects of ecosystem,society,economy and function,also the comprehensive effects in ecological engineering can be obtained.
