摘　　要：林草复合系统因生态、经济效益显著,各国已在广泛推广应用,也是林业和草业领域的研究热点。林草复合系统可增加林地空气湿度,降低气温和风速,减弱光照强度,减少自然灾害的发生;改善土壤理化性质,提高部分土壤养分含量,增加水土保持效益;另外可增加生物多样性。本文分析了林草复合系统对气象、土壤和生物多样性方面的影响,为林草复合系统的研究及推广提供参考与指导。Silvopastoral systems have been widely used all over the world due to its remarkable ecological benefits,and they has become hot topics in forestry and prataculture.The silvopastoral systems can not only increase the air humidity of the forest,but also reduce the temperature,wind speed and the light intensity as well as natural disasters.Besides,silvopastoral systems can also improve the physicochemical properties and increase some nutrient contents of soils to promote the benefits of soil and water conservation.Moreover,they can increases the biodiversity.In this paper,the effects of silvopastoral systems on meteorology,soil and biodiversity were analyzed,which will provide a guidance for the research and utilization of silvopastoral systems.
