| 摘 要： | 本文用Leslie矩阵模型研究了高寒草甸生态系统牲畜种群结构及动态。模型考虑了更加精确的年龄组转移关系,出栏率是种群波动的主要因子。目前,牲畜种群结构不合理,种群数量不能保持平衡。

| Abstract: | In this paper, the distribution and dynamics of livestock populations in alpine meadow ecosystem were studied by leslie matrix model. More exactly diverting relations among age-groups were considered in the model. Slaughter rate is the main factor affecting the population fluctuation. At present, the distribution of livestock populations is not rationally controlled for economic benefit and ecological efficiency, and the amount of livestock populations are not maintained in equilibrium state. |
