Abstract: In this paper, energy analysis of circular agriculture system of "Tea-livestock-forage-processing" was carried out. The results showed that manpower input was the main part in Tea garden-system and tea garden ecological system, accounting for 75.00% and 63.86% of total energy input, respectively. Corn as feed was the main part in circular agriculture system "Tea-livestock-grass-processing", accounting for 41.91% of total energy input human input for 21.16%. Net energy output rate, environment load rate and index of sustainable development of "Tea garden-processing" system showed the best, reaching 13.55, 0.31 and 44.22, respectively. Highest net benefit of energy was obtained in "Tea-livestock-grass-processing" system.
