以长白山林区天然异龄混交林为研究对象，基于4块固定标准地（总面积2hm 2）30多年的定株观测数据，采用Voronoi 图空间分割方法，对各树种潜在生长空间的确定，得到了各树种单位面积平均蓄积生长量。结果表明：各树种单位面积平均蓄积生长量出现最大值的径级各不相同；在长白山林区，对天然异龄混交林进行径级择伐作业时，云杉、冷杉、红松、椴树、枫桦允许保留的最大径级分别为46、44、40、36、28 cm。

In the natural uneven-aged mixed forest of Changbai Mountains , with four fixed standard ground of 2 hm2 and the con-tinuous data of 30 years, we used the Voronoi polygons to divide the space , and then discussed the relation between the size class and the volume growth in the unit area to determine the area potentially available of each species .The relation-ship between the different tree diameters class and the growth per unit area in different tree species was a unimodal curve , and the unimodal curve of the highest point on each were not identical .In the Changbai Mountains , when selective cutting operations in the natural uneven-aged mixed forest with different age , the largest diameter class was 46, 44, 40, 36 and 28 cm for spruce, fir, Korean pine, basswood, maple and birch, respectively.
