通过对 10年生豫西日本落叶松 (Larixkaempferi(Lamb .)Carr试验林不同密度主要生长因子的调查、研究及相关分析 ,建立了各性状同其密度间的相关数学模型 .利用模型提出了以生产纸浆材、小径材为目的的豫西日本落叶松人工林的最适初植密度是 2 0 0 0～ 2 5 0 0株·hm-2 ,以生产中径材为目的是 110 0～ 15 0 0株·hm-2 .
Through the investigation, analysis and correlation analysis of 10-year-old Larix kaempferi (Lamb.) Carr. Different density main growth factors, the correlation mathematic model of each density with its density was established.Using the model, The optimal planting density of Larix kaempferi plantation in West Henan is 2000 ~ 2500 plant · hm-2 for the purpose of timber production and small-diameter timber production, while 110 0-15 0 0 plants · Hm-2.
