沙地樟子松生长规律的研究

Growth Rules of Pinus sylvestris var.mongolica on Sandy land

通过对内蒙古红花尔基林业局经营的沙地天然樟子松的生长特别和分布规律的研究,结果表明:沙地樟子松生长在不同光照条件和不同密度的环境下,林木的高生长和胸径生长存在很大的差异,樟子松在疏林(0.3～0.5)时,高生长快,胸径生长正常,材积生长数高.

Growth characteristics and distribution rules of Pinus sylvestris var. mongolica on sandy land constructed by Honghuarji Forestry Bureau of Inner Mongolia Autonomous Region was studied. Results showed that growth in length and growth in DBH had significant differences. When the crown closure of Pinus sylvestris var. mongolica was 0. 3～0. 5,growth in length was fast,growth in DBH was normal,growth in volume was the biggest.
