科尔沁沙地沙化日益严重。为加快治理沙漠化的步伐,采用飞机播种造林。飞机播种具有速度快、省劳力、成本低等优点,所以愈来愈被地广人稀的沙区采用。为总结以往飞播经验,为以后有效地开展飞播造林工作,我们从1984年8月25日～9月20日对兴隆(?)林场1983和1984两年飞播造林成效各因子进行了调查,调查的方法采用等距机械抽样法。
Desertification in Horqin Sandy is increasingly serious. In order to speed up the pace of desertification control, use aircraft sowing and afforestation. Aircraft sowing has the advantages of fast speed, labor-saving, low cost and so on, so it is increasingly used by sparsely populated sand areas. In order to summarize past experience of aerial seeding and conduct aerial seeding afforestation work in the future, from August 25 to September 20, 1984, we conducted a survey of various factors affecting the effectiveness of airborne afforestation in Xinglong (?) Forest Farm in 1983 and 1984, Method using equidistant mechanical sampling method.
