利用牧草生长-消费模型优化草场放牧方案

Optimizing of pastures grazing pattern with biomass growth and consumption models

从理论上探讨了草场生态系统牧草的生长过程和消费过程 ,采用数学模型方法模拟了两者的动态变化规律 ,分析了两者在草场生态系统生态平衡中的作用机制 .运用牧草的生长和消费模型模拟特定生产周期内草场生态系统的累积牧草消费量 ,提出优化的草场放牧方案 。

This paper discussed the biomass growth and consumption processes in grazed pasture ecosystems from a theoretical point of view, simulated the dynamics of these two processes with mathematical models, and analyzed the mechanism of ecological balance in pasture ecosystems from the perspective of these two processes. With the proposed biomass growth and consumption models,the dynamics of cumulative biomass consumption during one production cycle was simulated, and the optimal grazing strategies of pastures were proposed. The results could be valuable for pasture grazing management in practice.
