| 摘要: |
| 该文针对黄土高原半干旱节水型区域的典型———甘肃省定西市农村发展沼气“三料”俱缺的现 状，将生态系统的基本原理运用到农业生产实际中去，根据生态系统内物质循环和能量转化的规律，利用 生物之间的生态关系，采用农业循环经济模式的关键技术，以沼气发酵生产为纽带核心，把种植、养殖联 结起来，充分利用节水型区域的雨水集流，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，对定西不同区域条件下以沼气为纽带的生态型能源农业经济模式进行试验示范，开 展对“三沼”综合利用的研究和推广，从而达到干旱半干旱节水型区域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、生态效益和社会效益。 |

| Abstract: |
| Aiming at the situation of the development of rural biogas in Dingxi City of Gansu province where is typ- ical for water-saving in semi-arid Loess Plateau region， this paper put forward the development of agricultural re- cycle economic mode， that is， taking biogas production as core， combining planting and breeding， using afflux rainwater in water-saving area to establish ecological circular system of ”grass + livestock + cellar + gas + cookers + high-efficiency agriculture”. And then the mode was demonstrated and extended in different regions of Dingxi， so as to achieve high efficiency in economy， agricultural production safety， waste utilization in rural areas， and regeneration of living energy in arid and semi-arid regions. |
| Key words: Dingxi energy of ecology pattern of agricultural economy experiment and demonstration |
