中南农田高效循环模式关键技术研究的几点思考

Consideration on Key Technology about Recycle Economic Mode of High Efficiency in Farmland Ecosystem in Central South China

由于中国农业生产片面追求高产高效,农业资源-环境的矛盾日趋恶化,并引起了社会和政府的广泛关注。加速发展农业循环经济是实现农业可持续发展的关键,且已成为21世纪全球的大趋势。提出了农田循环经济发展主要包括多产业复合的大农业发展模式、生态保护型农业发展模式、农业废弃物循环利用型发展模式;探讨了中南地区发展农田高效循环需重点关注的能量、物质循环和信息、价值流传递途径与转化效率;提出了中南地区主要农田循环模式中需重点突破的关键技术;并就中南地区循环农业的发展提出建议。

Because high output and high benefit was unilaterally pursuing in agricultural production in our country, the contraction of agricultural resource and environment became more and more deteriorated, which attracted general attention by society and government. The key measure to carry out sustainable development of agriculture is to accelerate agricultural recycle economics, which has also globally become main trend in 21st. The agricultural recycle economic mode including the broad agricultural development mode of multiple industries united, the eco-protected agricultural development mode and the agricultural wasted matter recycle using mode were presented; the pipeline and transforming efficiency of energy flow, matter recycle, information flow and value chain in farmland ecosystem being paid much attention in the central south China were discussed; the key technology in main farmland recycle economic mode being broke through was made clear, finally, rational suggestions on develop agricultural recycle economics in the central south China were proposed.
