以豫西伏牛山生长的日本落叶松为对象，以海拔高、土壤厚度、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、土壤厚、坡度以及降水量是影响日本落叶松生长的主要因子，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。
Taking Larix kaempferi growing in Funiushan of western Henan as an example, the main environmental factors of Larix kaempferi were analyzed with six factors as altitude, soil thickness, aspect, slope position, slope and precipitation. Regression equation of multifactor and tree height growth. The results showed that elevation, soil thickness, slope and precipitation were the main factors affecting the growth of Japanese larch. The slope position had some influence but the slope direction had no significant effect. Based on this, the optimal ecological conditions were determined.
