中文摘要：

在自然第二等的森林里的不同轻紧张下面的分数维的尺寸 ofPicea koraiensis 幼苗的变化被学习。结果证明与轻环境的变化，王冠人物 ofPicea koraiensis 幼苗在侧面的数字，侧面的增长，侧面的干燥重量，和特定的叶区域展出了更大的塑料。幼苗王冠的计算分数维的尺寸的范围在 2.5728 和 2.1036 之间被限制，但是分数维的尺寸的最大值在条款完成了中等 shading，处于极端低轻条件，分数维的尺寸是最少的。

英文摘要：

The changes of fractal dimension ofPicea koraiensis seedlings under different light intensities in natural secondary forests was studied. The results showed that with the change of light environment, crown characters ofPicea koraiensis seedlings exhibited a greater plastic in lateral number, lateral increment, lateral dry weight, and specific leaf area. The range of calculated fractal dimensions of seedling crowns was confined between 2.5728 and 2.1036, but maximum of fractal dimension achieved in term moderate shading and in extreme low light conditions fractal dimension was least.
