| 文章针对黄土高原半干旱区的典型———甘肃省定西市农村生态环境薄弱的现状，将生态系统的基 本原理运用到农业生产实际中去，利用生物之间的生态关系，以沼气发酵生产为纽带核心，把种植、养殖 联结起来，充分利用干旱半干旱区的雨水集流，建立起“种草+养畜+水窖+沼气+太阳灶+高效农业” 能源生态型良性循环体系，从而在半干旱区达到农村庭园经济高效化、农业生产无害化、农村废物资源化、 生活用能再生化，以获得显著的经济效益和生态效益。 |

| Abstract: |
| Ding Xi city of Gansu Province is the typical region of Loess plateau semi-arid region， and the ecologi- cal environment is bad. This paper applied the basic principle of ecological system into agricultural production， u- sing the relationship between biology and taking the marsh gas fermentation produces as link core to combine the cultivating and breeding， fully utilizing the rainwater flow concentration in the arid and semi-arid area， and estab- lished a virtuous circle energy ecotype system of”species grass + fostering livestock + water cellar + marsh gas + solar cooker + high-effect agriculture”. Thus we can realize the rural garden economy high-efficiency， agri- cultural production harmless， rural waste resource and household energy renewable. Therefore we could obtain sig- nificant economic benefit and social benefit. |
