以包头西郊防污林成活率、保存率、生长状况为依据，对工业污染区几种造林方法进行了比较研究。方差分析结果表明，植树坑中施绿肥造林、筑高台造林、水渠内造林是较好的造林方法，客土造林成活率高保存率低，常规造林成活率、保存率均低。因此，提出压绿肥造林，筑高台造林是工业污染区造林的主要方法。
Based on the survival rate, preservation rate and growth status of anti-pollution forest in the western suburbs of Baotou, several afforestation methods in industrial pollution area were compared. Analysis of variance showed that afforestation with green manure in planting tree pits, afforestation with high sets and afforestation in drains were better afforestation methods. The survival rate of afforestation by afforestation was low, and the survival rate and preservation rate of conventional afforestation were both low. Therefore, it is proposed that afforestation of green manure and construction of highland afforestation are the main methods of afforestation in industrial polluted areas.
