坡位对杉木纯林生长的影响
|
摘要
通过对不同坡位7年生杉木纯林生长的调查与研究,结果显示:坡位对杉木纯林各生长指标均有显著影响;林分的平均胸径、树高、冠幅、枝下高、平均单株材积、单位面积木材蓄积量等生长指标一致表现为下坡位>中坡位>上坡位。坡位间以胸径和树高差异最为显著,下坡位林分平均胸径达到10.59 cm,高出中坡位的11.6%,高出上坡位的20.0%;下坡位林分平均树高为7.25 m,高出中坡位的16.7%,高出上坡位的25.4%。下坡位林分的单位面积木材蓄积量要远远高于中坡位和上坡位的,下坡位林分的单位面积木材蓄积量分别高出上坡位的75.1%,中坡位的44.8%。
The research investigation on the growth of 7-year-old Cunninghamia lanceolata(Chinese fir) plantation under different slope conditions,the result showed that the slope position effect on the growth of pure Chinese fir plantation is significant. The growth indices of DBH, tree height, crown width,branch height, average individual volume,unit timber reserves of the stand were in the same order: downhill slope position>middle slope position>uphill slope position. The difference of DBH and tree height was the most significant among different slope position. The average DBH of Chinese fir stands on the downhill site reached 10.59 cm, which was 11.6% higher than that on the middle slope and 20.0% higher than that on the uphill slope position.The average tree height of Chinese fir stands on the downhill site reached 7.25 m, which was 16.7% higher than that on the middle slope and 25.4% higher than that on the uphill slope position.When afforestation is carried out in mountainous areas with steep slopes and large elevation spans, the unit timber reserves at downhill is much higher than that at middle and uphill slopes position. The accumulated yield of the Chinese fir wood in the downhill area was 75.1% higher than that in the up slope and 44.8% in the middle slope.
