| 摘 要： | 通过分析和综合肃南山地放牧系统的四季放牧试验数据,模拟了该系统的牧草供给与家畜需求的季节动态,用模式图反映了放牧系统牧草供需平衡机理。通过分析放牧系统的时间地带性的生态要素,拟合了肃南山地放牧系统的放牧函数,并建立了北半球中纬度地区的一般方程。这些模型数量化地解释了“生物的时间地带性”理论在山地放牧系统牧草供给与家畜需求平衡中的作用,对放牧管理和畜牧业持续发展具有一定的指导作用。

| Abstract: | Utilizing the theory of'Seasonal Livestock Production',with the mechanism plots herbage supply and livestock demand,a dynamic model was worked out by analyzing and integrating experimental data from the seasonal grazing lands of Sunan County.The grazing functions of seasonal grazing lands were given after analyzing the ecological elements of a theory termed the'Temporal Zonation of Biology'(TZB).These models quantitatively indicated the ecological process of herbage supply-livestock demand in the rotation grazing system,which were the expression of the theory TZB on a large scale.The above models and mechanism plots can aid in grazing management decisions of alpine rangeland and in the sustainable development of local livestock production. |
