放牧对人工草地植物群落演替影响研究进展

A Review of Studies on Effects of Grazing on the Succession of Vegetation Community on Artificial Grassland

根据人工草地植物群落的各种变化特征,可以及时掌握草地在放牧利用下的演替方向;适度放牧不但能促进牧草生长发育,提高牧草再生能力及营养价值,保持草地较高的利用价值,而且保护了草地的植物多样性,是维持群落稳定防止草地退化,有利于草地持续利用的重要措施。

Study on grazing-succssion of artificial grassland： according to all kinds of varied fatures of vegetation community on artificial grassland in time, we can grasp succession direction of artificial grassland under grazing utilization in order to adopt measure of corredponding cultivation. Grazed appro- priately can not only promote herbage growth , raise its recovery capability and nutrition value, but also maintain the higher utilized value. Keeping the balance of vegetation community and preventing grass degeneration, benefiting the sustainable utilization.
