| 摘 要： | 通过对不同林型的试验表明,日本落叶松与白桦、色赤杨混交林型能促进林木的生长发育,各项性状指标均优于日本落叶松纯林。各混交林型能改善林分土壤状况,提高土壤肥力,在不同林型中,乔木层物种重要值,日本落叶松纯林最大,基本为一个林冠层,而混交林有2个林冠层,在灌木层和草本层中,以混交林型物种数量最多,远远高于日本落叶松纯林。混交林的物种丰富度最大,数量最多,纯林的总数量仅为混交林的11%~37%。

| Abstract: | Through experiments of different forest types, mixed forest of Larix kaempferi , Betula platyphylla ＆ Alnus tinctoria can increase the growth and yield of forest trees; various character indices are all superior to pure forest of Larix kaempferi. Each mixed forest can improve soil conditions ＆ fertility. Among different forest types, species important value of tree layer of pure forest of Larix kaempferi which is basically one canopy layer is the most ; whereas mixed forest have two canopy layers, in shrub layer ＆ herb layer, quantity of mixed forest species are the most, much higher than that of pure forest of Larix kaempferi. Species richness ＆ quantity of mixed forest are all the most; total quantity of pure forest is only 11% - 37% of the mixed forest. |
