以小兴安岭用材林为研究对象，在天然林以及人工林内各设置抚育间伐强度不同的6块样地，每块样地设置4种带宽，以未采伐样地为对照，研究不同抚育方式对林分土壤化学性质的影响。经过对采伐后样地内土壤化学性质的测定，结合主成分分析方法，对实验数据进行分析，结果表明：小兴安岭天然用材林的最佳抚育方式为10 m带宽，25％～30％强度的抚育间伐；小兴安岭人工用材林的最佳抚育方式为14～18 m带宽，20％强度的抚育间伐。

An experiment was conducted to study the effects of different tending fellingpatterns on soil chemical property of tim-ber stands in Xiaoxing’ an Mountains by setting six sample plots on different cutting intensities withfour kinds of bandwidth in eachsample and a plot without cutting as a contrast .After the soil chemical properties were investigated to deal with da-ta in the cutting sample plots by principal component analysis.The tending felling pattern under 10 m bandwidth and 25%-30%intensity is the best for natural timber stands in Xiaoxing’an Mountains.The tending felling pattern under 14 m-18 m bandwidth and 20%intensity is the best for artificial timber stands in Xiaoxing’an Mountains.
