摘      要：The integrated circular economy model of farming and stock raising(ICEMFSR)has attracted increased attention as an effective model for solving the current irrational allocation of agricultural resources and realizing the agricultural value-added industrial *** study uses emergy analysis to comprehensively examine and evaluate the economic benefits,environmental pressures,and sustainable development levels of ICEMFSR in Shucheng County,*** results show that the ICEMFSR possesses the value of popularization with optimally allocated resources in the studied region,in which the emergy yield ratio(EYR),emergy loading ratio(ELR),and emergy sustainable index(ESI)in this model accounted for 3.59,1.25,and 2.89,*** result indicates a leading position in the national agricultural ***,this study constructs a new model based on the coupling of emergy evaluation and multi-objective linear programming to study ***,the EYR,ELR,and ESI respectively varied by +24.23%,10.40%,and +38.06%after replanning of *** variation implies a significant improvement in the sustainable development level of the *** addition,the optimized scenario design for key substances is proposed based on traceability and the reduce-reuse-recycle principle,including biogasification of crop straw and enhancement of crop scientific planting capacity.
