草地植物和草食动物的协同进化在草地管理上的作用

Effects of coevolution between herbivores and herbages on range management

在天然草地放牧系统中,草地植物与草食动物是同时进化的.草食动物的选择性采食作用保证其采食日粮具有较高的营养价值,植物对食草作用的适应所形成的抗牧性反应又使植物减少了来自动物采食的危害.草地植物与草食动物的协同进化关系成为维持草地生态系统稳定的基础.

In the natural range system, domestic herbivores and herbages were co-evolutional. The selective gazing of animal ensures the high content of nutrition in the indigested diet. The negative effects of selective grazing would be reduced due to the adaptation of herbages to foraging. The coevolution between herbivore and herbage would be the fundament for sustaining stability of the range ecosystem.
