对白龙江林区云杉人工更新造林与立地因子关系进行了调查,并应用数量化理论Ⅰ进行了立地因子与成活率关系的分析,得出海拔和坡向是影响成活率的主导因子。造林3年后,再调查主导因子对3年保存率及3年高生长影响,经分析得出海拔越高,3年保存率越低,并且阳坡比阴坡更低;随海拔升高,云杉年高生长量下降。研究结果表明:海拔3000m以下适宜云杉生长,海拔3000m以上不适宜云杉生长,为云杉栽植超适生区,人工更新造林应更换树种。
The relationship between the artificial regeneration afforestation and the site factors of the spruce in Bailongjiang forest area was investigated. Based on the quantitative theory I, the relationship between the site factor and the survival rate was analyzed. It was concluded that the elevation and aspect were the main factors affecting the survival rate. After 3 years of afforestation, and then investigate the impact of the dominant factor on the 3-year conservation and 3-year growth, the higher the altitude, the lower the 3-year preservation rate, and the sunny slope is lower than the shady slope. With the elevation increasing, Spruce height growth declined. The results show that the suitable spruce below 3000m is suitable for growing spruce above 3000m above sea level, which is unsuitable for spruce growth.
