摘要
乌拉特后旗境内乌兰布和沙漠风沙危害严重,地形特殊,经过长期的生产实践,文章总结了以尼龙沙障和柴草沙障为主的工程固沙方法和以梭梭(Haloxylon ammodendron)、花棒(Corethrodendron scoparium)等抗旱树种为主的造林方法。成效调查结果表明:当年造林成活率达91.0%~94.4%,第三年造林保存率达86.4%~89.4%,植被覆盖度达到40%。该治理方式可在乌兰布和沙区有灌溉条件、地势平坦、集中连片的重点治理区推广。
The Ulan Buh Desert within the territory of Urad Rear Banner suffers from severe wind and sand hazards and has unique terrain.After long-term production practice,this paper summarizes the engineering sand control methods mainly using nylon sand barriers and brushwood sand barriers,and the afforestation methods mainly using drought-resistant tree species such as Haloxylon ammodendron and Corethrodendron scoparium.The effectiveness survey results show that the survival rate of the afforestation in the year of planting reached 91.0%~94.4%,and the preservation rate of the afforestation in the third year reached 86.4%~89.4%,with vegetation coverage reaching 40%.This management method can be promoted in key management areas of the Ulan Buh sand area with irrigation conditions,flat terrain,and concentrated contiguous areas.
