紫椴人工幼林适生立地条件分析

Analysis on Suitable Site of Young Tilia amurensis Plantation

文章用标准地对比分析方法研究了相同年龄不同立地条件不同混交类型紫椴人工幼林生长的特点。结果表明：紫椴人工林坡上和坡下生长较差，在山中部立地条件下生长较好，在坡度为６～２５°范围内对紫椴幼林生长影响不明显；土壤Ａ层厚与幼林生长有密切关系；在三个混交类型中落椴混交比红椴混交和云椴混交效果好。在造林时选择适宜的立地条件和混交类型对紫椴幼林生长是非常重要的。

The growth characteristics of young Tilia amurensis (Amur linden) plantation under different sites and mixture types at the same ages were studied by comparing standard plots. The results show that the growth on the upper and lower slope positions is poorer, while it grows better on the middle slope. The influence of the slope within 6～25° upon its growth isn't evident. There is a close relationship between the thickness of A layer in the soil and its growth. The mixture effect of Dahurian larch and Amur linden is better than that of Korean pine and Amur linden, Chinese spruce and Amur linden. It is very important to select suitable site and mixture types in the process of planting trees.
