摘要
在祁连山浅山区选择适宜的造林树种,采用科学的栽培配套技术进行造林试验,研究不同立地因子对造林成活率和生长量的影响,结果表明:祁连山浅山区随海拔和坡向的不同,其造林成活率的高低有差异,由高到低依次为青海云杉>华北落叶松>沙棘>圆柏;青海云杉、祁连圆柏和华北落叶松分别在海拔2 800、2 900和2 800m时有最大生长量;浅山区造林土壤含水量比对照提高了64.3%。
Appropriate afforestation species were selected in shallow hillside and alone the shallow mountain area of Qilian Mountain,adopting scientific cultivation technologies to conduct afforestation experiments.The effect of different factors on the survival rate and growth were studied.Result shows that：the height of survival rate of afforestation have differences with the difference of altitude and aspect in shallow mountain area of Qilianshan Mountain.The descending order of Picea crassifolia〉Larix principis-rupprechtii〉Hippophae rhamnoides〉Sabina chinensis;Picea crassifolia,Sabina przewalskii Larix principis-rupprechtii have the great growth at the altitude of 2800 m,2 900 m 2800m.Soil water content in shallow mountain area of increase by 64.3%than that of CK.
