| 摘 要： | 家畜的能量流和能量的转化效率是家畜生产力的重要指标。在草地生态系统中,草食动物是能量和物质转化的重要环节。草地生态系统的能流,从第一性生产(总初级生产)到第二性生产的最终产品(净次级生产)至少要经过六个转化阶段。要加速能流和提高能量的转

| Abstract: | The energy intake and its loss through faeces, urine and methane of Capra hircus population in brush grassland ecosystem in northwest Sichuan province mountainous region are measured and quantities of energy in digestion, metabolism and net fat accumulation are calculated. Energy flows between green plants and Capra hircus population and its conversion efficiencies within a hectare of grassland are studied. |

| Keywords: | Capra hircus grassland ecosystem energy flow energy conversion efficiency. |
