【摘要】 放牧地生态系统占据草地生态系统的最大比例,对它的研究关系到草地畜牧业生产稳定和发展,也关系到我国生态环境的好与坏.研究放牧地生态系统重点在于放牧地生态系统的构成,放牧地植物与放牧家畜的生态关系,放牧方式和放牧强度.结果表明,人是放牧地生态系统构成的重要组成成分;放牧地植物与放牧家畜的生态关系是相互影响、相互制约、相互适应、相互促进的协调关系;在不同类型草地上以不同形式的混牧可获得好的生态经济效益;适度放牧是放牧地生态系统的基本原理和放牧管理的基本原则.更多还原

【Abstract】 The Grazing land Ecological System occupies the largest proportion of grassland ecological system,it is related to the stable production and development of grassland animal husbandry production for research,and it is also related to China’s ecological environment of good and bad.Grazing land ecological system structure,Pasture plants and grazing animal livestock ecological relationships and Herding way and the grazing intensity are grazing land ecological system’s important poits.The results show that people are important component of pasture ecological system;Grazing land plants and grazing livestock ecological relationship is mutual influence,mutual restrict,suit each other,promote of the development;In different grassland types with different forms of grazing can obtain good ecological and economic benefits;Moderate grazing is grazing land ecological system theory and the basic principle of grazing management.更多还原
