为了加速我国西北地区沙漠的改造,实践证明利用飞机播种造林是一项卓有成效的措施。苏联早在1931年开始在中亚半固定沙地上飞播梭梭。我国1658年在陕西榆林沙区首次飞播,到1678年计播种面积116万亩。我区1959—1960年先后在巴彦淖尔盟的腾格里沙漠、乌兰布和沙漠和伊克昭盟的库布齐沙漠计雨季飞播271.4余万亩,占同期全国总飞播面积的66.2%。1975年昭乌达盟在东部沙地飞播治沙1.6万亩。伊克昭盟1978年在毛乌素沙漠飞播杨
In order to speed up the transformation of the desert in the northwest of China, practice has proved that the use of aircraft sowing afforestation is an effective measure. As early as 1931, the Soviet Union started to shuttle the shuttle Sosa on semi-fixed sandy land in Central Asia. In 1658, our country first sowed in the sand area of Yulin, Shaanxi Province. By 1678, the planting area was 116 million mu. In the period from 1959 to 1960, the I-zone flew over 271.4 million mu in the rainy season in the Tengger Desert, Ulan Buh Desert and Uyghur Autonomous Region of the Bayannure League in the Kubuqi Desert, accounting for 66.2% of the total national total sown area over the same period. In 1975, Zhaowuda League flew over 16,000 mu of sand in the east. Yikezhao League in 1978 flying in the Mausu desert Yang
