摘　　要：通过对6年生桤木3种造林密度及3种坡位林分的胸径、树高、蓄积以及投入产出进行分析,结果表明:造林密度对桤木胸径生长有显著影响;坡位对桤木胸径生长有极显著的影响,对树高和蓄积均有显著影响;在以"品"字形放样的前提下,选择以2501株/hm2的造林密度及下坡营造桤木纸浆林经济效益最好。Based on the analysis on breast height, height, volume and investion put in or out of three kind afforestatim density and three forest slope stand of six-year-old Alnus cremastogyne. The results showed that： There was obvious effects on breast height growth of Alnus cremastogyne in differe afforestation density. There were obvious effects on breast height growth of Alnus cremastogyne, and effests on height and volume growth. The afforestation density in 2 501 plants per hm^2 and afforest in low slope with plant in traingle place is the best economic benefit for afforestation of Alnus cremastogyne pulpwood.
