摘要以15块人工落叶松纯林演化后形成的落叶松云冷杉混交林为对象，间伐后12年观测结果，研究间伐对林分和树木生长、树种组成、物种多样性及土壤等因子的影响。 - The fractal dimension of the mixed forests were lower than the pure forests and grassland , and the soil weight diameter of the mixed forests were higher than the pure forests and grassland , which indicated that the mixed forest had best soil structure property in stability infiltration and water - holding ; the soil total porosity and the soil noncapillary porosity were different greatly between forest types , but the soil capillary porosity had little differ
混交林分分形维数均低于单纯林与荒草地，土壤重量平均直径均高于单纯林与荒草坡，说明混交林土壤结构稳定性最好，土壤通透性较好，具有较高的水土保持功能；不同林分类型之间，土壤总孔隙度与非毛管孔隙度差异较大，而毛管孔隙度的差别较小。
