Low carbon agricultural production process strictly follows the principle of joint production,aiming at decoupling the relationship between agricultural products and carbon emissions products or strengthening the relationship with carbon sink products,then achieved relatively low entropy of agricultural production system. Six low carbon agriculture development models are formed in the actual process of agricultural joint production. The result of agricultural carbon measurement model shows that there were some differences in the total and unit carbon output of the different low carbon agriculture joint production models,but it finally all achieved a good net carbon sink effect. Meanwhile,no-tillage,straw returning and manure allocation measures were helpful to maintain soil carbon sequestration in the cultivated land,while standardized integration of agricultural technology was beneficial to realize carbon sequestration and emission reduction effect in agricultural production process. The results of DEA-RAM Model showed that M3 model reflected a high level of joint production efficiency and achieved the best performance in economic and ecological aspects. However,the inefficiency of joint production performance causes the redundancy of agricultural input. The behavior choice of farmers had an important influence on the input of capital,labor and technology in the low carbon agriculture joint production process,and significance and importance of influencing factors in different models also demonstrated some differences.
