摘要
为提高草沙地系统稳定性,采用阔叶树混交方式营建草沙地防护林。树种配置以乡土、牧用树种为主,体现了树种的多样性。阔叶树易萌发、生长快,落叶可以被牲畜直接利用,增加了草地牧业利用的产量。沙地草地阔叶树混交林的营建,发挥了以林保草、以林促牧的作用,有利于建立林草复合经营模式。
Protection Forest on sandy meadow was established by mixing broadleaf trees to raise stability of sandy meadow system.The main tree species used were native and usable for pasture and achieved diversity of speaies.Broad leaf,trees,having advantages,easy to sprout,fast growing,that leaves of the trees can be ased by livestocks,have raised productivity of meadow animal husbandry.Establishment of the broadleaf mixed forest is of effects in grass protection and lifestock raising and beneficial to establishing forestgrass integrated management model.
