摘要
对贵阳市花溪区马铃乡不同坡位、坡向30年生马尾松人工林主要生长指标进行测定、分析。结果表明:不同坡位树高、胸径、单株材积的均值次序为:下坡>中坡>上坡,不同坡位对树高生长有显著影响,对胸径、单株材积生长的影响达极显著水平;不同坡向树高、胸径、单株材积的均值次序为:阳坡>阴坡,不同坡向只对胸径生长有显著影响,对树高和单株材积生长的影响不明显;马尾松人工林在下坡和阳坡生长较好。
The preliminary determination and comparative analysis of main growth indexes of the 30 years Pinus massoniana Plantation in Guiyang Huaxi District Maling Township at the different terrain （slope position, slope） was conducted. The results showed that tree height, DBH, individual volume means in different slope positions were followed order as down - slope 〉 middle - slope 〉 up - slope. The different slope positions had significant effect on tree height growth, the effect on DBH; individual volume growth reached extremely significant level. The tree height, DBI-I, individual volume means in different slope were followed as sunny - slope 〉 shady - slope. Different slope only had a significant effect on the growth of DBH, the effect on tree height and individual volume growth were not obvious. Pinus massoniana plantation in Maling Township was grew better in the down -slope and sunny -slope.
