Résumé
The Kubuqi desert sits on the Erdos plateau,is the seventh largest desert in China,after years of governance,the Kubuqi desert has gradually formed a business model and pattern of"taking sand control as the center,science and technology as the forerunner,combining forestry,sand,grass and livestock,and diversified management and comprehensive utilization".The development of the sand industry has made important contributions to improving the local ecological environment,promoting economic development and improving people’s well-being.However,through field research,it was found that the current industry chain was short,and the end wastes were not effectively reused,thus resulting in the waste of resources and environmental impacts.At present the study of sand industry mainly focus on the understanding and the understanding of the concept,and the combination of theory and practice research relatively blank,at the same time,based on life cycle assessment(LCA)on Lin Sha breeding industries,research focuses on pigs,cattle,poultry breeding in the process of evaluation,and for"cultivate-breed-process"industrial chain breeding mode has not yet have a comprehensive study,In this context,based on a representative enterprise of the sand industry in Kubuqi desert,through field research and collection of relevant data,two scenarios are set.Scenario 1 is set according to the traditional rex rabbit breeding industry chain,and scenario 2 is set by improving and extending the follow-up links of the industry chain.Based on life cycle assessment(LCA)method,a life cycle inventory of both scenarios is built,then the SimaPro software is used for life cycle impact assessment,and the environmental impacts of the rex rabbit industry chain and the circular rex rabbit industry chain were obtained and compared.
