摘要/Abstract

摘要： 本文研究了高寒草甸生态系统牲畜种群的线性规划模型和最优利用策略。以门源马场牧场的实际数据作为模型的一个例子,分别提出了藏羊、改良羊和牦牛的最优种群结构和最优出栏方案。在改良羊、藏羊、牦牛和马为主的牧场上,改良羊是牧场上的主要牲畜,牦牛和马保持其数量下限,藏羊全部淘汰。在藏羊、牦牛和马为主的牧场上,藏羊是牧场上的主要牲畜,牦牛和马保持其数量下限。按照线性规划模型方案经营,可提高经济收益,并减轻冬舂草场上牲畜的过多采食。价格分析说明青海省现行的畜产品价格体系需要调整。

Abstract: Empirical data on the menyuan horse farm grazingland in Qinghai of. China were used for linear programming model and optimal exploitation strategy study. The optimal population structure and optimal slaughter program of tibetan sheep, improved sheep and yak were put forward respectively. On grazingland where livestock populations are composed of tibetan sheep, improved sheep, yak and horse, improved sheep is a principal ingredient, amounts of yak and horse are kept at quantitatively lower limit, and tibetan sheep is totally eliminated. On grazingland where livestock populations are composed of tibetan sheep, yak and horse, tibetan sheep is a principal ingredient, and amounts of yak and horse are kept at quantitatively lower limit. Based on this program to manage the grazingland, the economic revenues can be increased. And these programs can lighten over intakes of livestock populations at the grazingland in winter and spring. The price analysises demonstrate that the current price system of livestock products need to be readjusted in Qinghai province.
