摘要
农业系统的循环经济建设包含了农业生产、资源再生和环境保护三方面的内容。本文介绍了北京蟹岛生态园区循环经济的建设成果,从农业小循环、产业大循环和资源循环再生三个方面总结了蟹岛循环经济模式的特点,并对蟹岛园区各个子系统的能量利用结构和效率进行了研究。结果表明,系统总的能量产投比2.2,能量利用效率较高,系统结构趋向合理化,取得了较好的经济、生态和社会效益。
Circular Economy （CE） development of agriculture system contains three aspects： agriculture production, recycle of resource and environmental protection. We introduced the work of CE construction in Xiedao Green Environmental Holiday Village, Beijing, China. Characterized Xiedao CE pattern through micro-circulation in agriculture, macro-circulation in industry and material circulation. The structure and efficiency of Energy use are studied, it turns out that the ratio of energy I-O is 2.2, which indicates Xiedao system has done well in energy use with reasonable structure.
