| 摘 要： | 为了研究高寒牧区经济生态复合系统的能量结构与功能,作者对青海门源种马场和其中一个家庭牧场1987～1988年生产情况进行了详细调查,以系统的观点分析了大牧场及其家庭牧场生产系统的能量结构与转化效率。计算出青海门源地区大牧场生产系统的能量转化效率为:太阳辐射能→牧草地上部分0.037％,牧草地上部分→畜群51.10％,畜群→家庭牧场2.15％,家庭牧场→大牧场61.61％,大牧场→系统外13.88％。全系统的能量转化效率(太阳能→系统外)为:3.5×10~(-7)。

| Abstract: | To study the enerey structure and functions of social—economic—natural complex ecosystem in alpine pastoral area, the 1987～1988 productive conditions of Menyuan horse farm in Qinghai and one of its family ranges were investigated.Their energy structure and conversion efficiency were analysed systematically and calculated:solar radiation→grass above ground 0.037%,grass above ground→livestock herd 51.10%,livestock herd→family range 2.15%,family range→ranch 61.61%,ranch→ out-ranch 13.88%.The conversion efficiency of total productive system is 3.5×10~(-7). |
