摘要
采用能值分析方法对"茶—畜—草—加"循环农业系统进行能值分析,结果表明:"茶园—加工"系统和茶园生态系统以人力投入为主,分别占总能值投入的75.00%和63.86%,"茶—畜—草—加"循环农业的主要投入为玉米饲料等,占总能值投入的41.91%,人力占总能值投入的21.16%;"茶园—加工"系统在净能值产出率、环境负载率和可持续发展指数等多个能值指标中均最优,分别为13.55、0.31和44.22;"茶—畜—草—加"循环农业系统的能值净收益最高。
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.
