| 摘 要： | 通过对新疆北部半农半牧区养羊牧业生态系统连续二年多的测定,对牧业系统的结构及其主要系统能量投入产出、能量在牧业食物链流动和变化、系统生态效益作了定量的分析和测定。结果表明,该地区养羊牧业生态系统中初级生产中光能利用率为0.13％,次级生产中饲料转化率为2.7％,都属于偏低水平。本文对此作详细讨论,认为虽然目前每户年收入超过万元,但生产潜力仍很大,针对该地区生态系统能流特征,提出相应措施,以期对今后生产发展提出可靠依据。

| Abstract: | on the spot tests during 1987-1989, the quantitative analysis and calculation of input-output ratio of energy as well as eco-efficiency of main subsystems have been conducted. The results show that the utilization rate of solar energy is 0. 13% in the section of primary production and ratio of second production is 2. 7%. All stay at lower rates, however, which is discussed and the general characteristic of energy flow in ecological Agro-system of familyhood sheep farm there has been given in this paper. |
