摘　　要：针对不同立地荒山分别试验环山掘壕、环山深拉沟、环山拉沟侧筑埂等整地形式，测定、比较不同整地形式与对照对土壤水分含量、土壤理化性质的影响，不同整地形式的造林成活率及林木生长状况。结果表明，掘壕整地可使造林成活率提高20多个百分点，林木初期高生长提高20％以上，环山深拉沟及环山拉沟侧筑埂整地可使造林成活率提高10～20个百分点，林木初期高生长提高10％以上，造林效果显著。Respectively for different mountain trials demonstrated land consolidation forms, such as deep trench, dug trenches, gully side built dikes and so on. Effects of different land consolidation forms and control on soil moisture and physical and chemical properties were deter-mined and compared, as well as the afforestation survival rate and forest growth status by different land consolidation forms. The results showed that, dig trenches can improve afforestation survival rate more than 20% , and forest height in initial period improve more than 20% , deep trench and gully side built dikes can improve afforestation survival rate 10% -20% , forest height in initial period improve more than 10% , the afforestation effect is significant.
