Abstract: 【Objective】To construct an evaluation index system for the windbreak and sand-fixing technology model of Cyperus esculentus guided by ecology,life and production integration concepts,so as to provide references for evaluating the actual efficacy of the technology model,adjusting and optimizing the technical plan,and broadening the path selection of ecological management technology in windy and sandy areas in northern China.【Methods】The evaluation indexes and their corresponding weights of windbreak and sand-fixing technology model of Cyperus esculentus guided by ecology,life and production integration concepts were determined by using target hierarchy method,Likert scale method,analytical hierarchy process method and expert grading method.【Results】An evaluation index system composed of the target layer,the criterion layer and the index layer was constructed,and there were 11 ecological effect indexes,6 economic effect indexes and 6 social effect indexes in the constructed evaluation system. Furthermore,the weight for each evaluation index was determined. The weights of ecological effect,economic effect and social effect in the criterion layer were 0.568,0.229 and 0.203,respectively.【Conclusion】Ecological effect had higher weight in the windbreak and sand-fixing technology model of Cyperus esculentus guided by ecology,life and production integration concepts. Through consistency check and actual test,the index weights of the constructed evaluation index system were compatible with the technology research and development goals,and were adaptive to the characteristics of the ecological environment in windy and sandy areas in north China and the industry development status of Cyperus esculentus.
