应用计盒维数对长白山原始阔叶红松林中主要乔木树种种群空间格局进行的研究表明，样地内乔木树种中裂叶榆种群的计盒维数最大，为1．888。在群落中占据最大的生态空间；簇毛槭、白牛槭、紫椴和五角槭的计盒维数都在1．8以上，与裂叶榆在群落中处于优势地位；其他树种依据计盒维数的大小在群落中占据相应的生态空间。所研究各树种拐点尺度从5～31 m不等，但均大于其平均冠幅，所有树种全部为聚集分布，拐点尺度代表了相应树种的聚块大小。这与其他学者的研究结果相符，说明计盒维数具有较高的准确性和实用性。

An investigation was conducted to analyze the scale variation degrees of major trees species population in broad-leaved Korean pine (Pinus koraiensis) forest in Changbai Mountain by using box-counting dimension.Ulmus laciniata population occupies the largest ecological space because of its biggest box-counting dimensions (1.888).Acer barbinerve, A.mand-shuricum, Tilia amuer nsis and A.mono populations are highbox -counting dimensions (>1.8), and they are at dominant species of these forest types as U.laciniata population.Other trees species population occupies the corresponding ecologi-cal space for their respective box-counting dimension.The inflexion scales of the studied populations covered from 5 m to 31 m, greater than the average crown width.Therefore, all the studied species are aggregately distributed and the inflexion scale represents the scales of blocks .The results with the high practicability and accuracy of the box-counting dimension are in consistent with the previous analysis.
