摘要
本文分析了小张庄村1976—1987年畜牧业的发展特点,并着重分析了1987年该子系统的能量和物质的转化特征。指出目前小张庄村生态系统是稳定的,但效率低。要将其建设成为既稳定又高效的农业生态系统,必须从畜牧业子系统着手,提高饲料转化率。
The paper analyses the characteristics of animal husbandry subsystem in xiaozha-ngzhuang village during 1976-1987, and focuses on the characteristic of energy and matter conversions in the subsystem in 1987.
