摘　　要：以豫西伏牛山生长的日本落叶松为对象，以海拔高度、土层厚度、坡向、坡位、坡度和降水量等６个因子为指标，进行了日本落叶松生长主要环境因子分析，建立了多因子与树高生长的回归方程。结果表明，海拔高度、上层厚度、坡度以及降水量是影响日本落叶松生长的重要因子，坡位有一定的影响，坡向影响不明显。据此确定了其最适生态条件。this paper took Larix haempferi growing in Funiu mountain in the west ofHenan provice as studying material,the major ecological factors affecting the growth ofLarix haempferi,including altitude,soil layer thickness,slope orientation,slope place,slopeand rainfall,were analysed.The regression equation has been established between the lar-ix haemferi height growth and the ecological factors.The results show that altitude,soillager thickness, slope and rainfall were important factors affecting the growth of Larixhaempferi that slope place has a certain effect,and that the effect of slope orientation wasnot obvious. Based on this,the optimum ecological condition of Larix haempferi is deter-mined.
