昭乌达盟北部和东部是我国畜牧业基地之一,全盟草原总面积为8974.955万亩,占全盟土地总面积的70.4％。六十年代中期以来,由于过度开垦和不合理的放牧,因而使草原生态平衡遭到破坏,从而导致草场退化和沙化。目前全盟退化和沙化草场面积已达2752万亩,其中严重者1689万亩。为了防止草场继续退化和沙化,恢复草原生态平衡和草原生产力,我们从1971年开始在昭乌达盟巴林右旗短角牛场和白彦尔登草原站进行了牧场防护林营造技术的试验研究。目前已营造牧场防护林 Zhaowuda League north and east of China’s animal husbandry base, the AU grassland total area of ​​89,749,500 mu, accounting for 70.4% of the AU land total area. Since the mid-1960s, due to over-exploitation and irrational grazing, the ecological balance of the grasslands was destroyed, resulting in the degradation and desertification of grasslands. At present, the area degraded and sandy grassland has reached 27.52 million mu, of which 16.89 million mu are seriously affected. In order to prevent grassland degradation and desertification and restore grassland ecological balance and grassland productivity, we conducted experimental studies on the technology of pasture shelter planting in 1971 in the Balinjouan cattle farm and the Baiyeldeng grassland station in Zhaowuda. Ranch shelter has now been created
