| 摘 要： | 由于深栽旱作造林密度过大出现林木早衰甚至死亡问题,从树种生物生态学特征、造林方式、立地条件、水分平衡、伴生树种等方面加以论证,认为深栽旱作造林密度应配置成均匀而比较稀疏的群体结构。

| Abstract: | Trees happened premature decay and even die due to density too dense in deep forestation no irrigation.It is considered that thin construction were disposed in density of deep forestation no irrigation from tree biological ecology characters,forestation pattern,site conditions,water balance,auxiliary tree species and so on. |

| Keywords: | High elevation Sandy Deep forestation Rational density |
