摘要
本研究根据高寒草甸生态系统中草-畜能量流动态,采用Shiyomi的分室模型方法,建立高寒草甸放牧生态系统的分室模型,做为定量分析高寒草甸生态系统放牧管理和进行最优控制研究的基础。系统模型由8个分室组成:地上生活部分、地下活根、地下死根、地上枯枝落叶Ⅰ(易分解部分)、地上枯枝叶Ⅱ(不易分解部分)、绵羊采食量、绵羊活重、粪便。8个分室之间的能量流用8个联立的常微分方程描述。
Comparment modelling of alpine meadow grazing ecosystem is constructed on the basis of the energy dynamics of grass-livestock in alpine meadow ecosystem by using Shiyomi compartment modelling method. It will be used for analysing grazing management quantitatively and optimum control. This system model consists of eight compartments; above-ground plant portion, below-ground live portion including roots, below-ground dead portion including roots, above-ground litter I (perishable portion), above-ground litter Ⅱ (unperishable portion), sheep intake, sheep liveweight, faeces. Energy flows between the eight compartments are described by eight simultaneous differential equations.
