以9块华北落叶松人工林标准地及9株解析木为研究对象,通过对不同坡向条件下(曼甸、阳坡、阴坡)华北落叶松人工林生长、生物量及生产力进行研究,结果表明,华北落叶松具有较好的适应性,在3种立地中曼甸上华北落叶松的胸径生长较大,树高差异不明显;同一林龄条件下,曼甸林分的生物量较阳坡、阴坡的大;各组分的含碳量以曼甸的最大,阴坡、阳坡差别较小;曼甸的生产力>阳坡>阴坡。
Based on the standard stands of 9 Larix principis-rupprechtii plantations and 9 analytical stands, this paper studied the growth, biomass and productivity of Larix principis-rupprechtii plantations under different slope conditions (Mandeng, Yangpo and Shady) The results showed that Larix principis-rupprechtii could adapt well. The DBH of Larix principis-rupprechtii in the three habitats was relatively large, and the difference of tree height was not obvious. Under the same stand age, Sunny slope, and large shady slope. The carbon content of each component is the largest in the Mendian, the difference between the shady slope and the sunny slope is small, and the productivity of the Mendan> the sunny slope> the shady slope.
