摘要: 研究旨在探明“水稻/牧草-肉牛-有机肥-蔬菜/茶叶”循环农业模式能量流动的规律,应用能值分析方法对长沙县金井镇“水稻/牧草-肉牛-有机肥-蔬菜/茶叶”循环农业模式的投入和产出进行分析,对能值自给率、环境负载率和可持续发展指数等进行探讨。结果表明:“水稻/牧草-肉牛-有机肥-蔬菜/茶叶”循环农业模式的资源利用效率为49.00%,环境资源对农业的贡献较大;环境负载率为1.14,系统生产过程对环境压力较小;全系统净能值产出率和可持续发展指数分别为7.41 和6.49,系统的生产效率较高,富有活力和发展潜力。该模式通过对牛粪尿、狐尾藻等资源的循环利用能有效降低环境的压力,提高农业生态系统的可持续发展指数,实现农业良性循环和可持续性发展。

Abstract: The paper aims to explore the energy flow law of circular agriculture mode of“rice/grass-beeforganic fertilizer-vegetable/tea”, analyze its input and output by the emergy analysis method in Jinjing of Changsha and discuss the emergy self-support ratio, environmental load rate and sustainable development index. The results showed that resource utilization rate was 49.00% and the environmental resources made great contribution to agriculture; environment load ratio was 1.14 which indicated that the production process of the system had less pressure on environment; net emergy yield ratio and sustainable development index of the whole system were 7.41 and 6.49, it illustrated that the production efficiency of the system was high, and full of vitality and development potential. The cyclic utilization of cow dung and watermifoil could reduce environmental pressure, improve the sustainable development index of the agricultural ecosystem and realize the positive circle and sustainable development of agriculture.
