摘　　要：应用分形分析中的计盒维数对长白山原始阔叶红松林样地内15种主要乔木树种垂直结构上4个层次的空间分布格局进行研究,结果表明:4个层次从下到上优势种分别是:簇毛槭、白牛槭、五角枫和紫椴。紫椴、五角枫和白牛槭在以后的群落演替中将处于优势地位,而裂叶榆和枫桦的优势地位将衰退;红松在群落演替的过程中会出现先衰退后逐渐恢复优势地位的现象,其他树种在群落中优势不明显,处于伴生地位,仅个别树种在特定层次处于优势地位。五角枫、千金榆、白牛槭、簇毛槭和稠李等树种的空间分布格局聚集强度随年龄增长而减弱,其他树种均不符合该规律。The study was conducted to analyze the spatial distribution pattern in tour levels of the vertical structure of 15 main tree species in the plot by using box-counting dimension. Four levels of the dominant species from bottom to top are Acer barbinerve, A. mandshuricum, A. mono and Tilia amurensis. T. amurensis, A. mono and A. mandshuricum are in the dominant position in the future community succession, and the advantage position of Ulmus laciniata and Betula costata de clines, while Pinus koraiensis decreases and then increases. Others showed the low spatial occupation degree in accompani ment position in the forest, and only individual species is in a dominant position in particular levels. With the age increas ing, A. mono, Carpinus cordata, A. mandshuricum, A. barbinerve and Padus racemosa have decreased aggregation inten sity in their spatial distribution, while other species have not obvious change.
