【目的】

了解间伐强度对塞罕坝地区樟子松人工林生长及林下植物物种多样性的影响，为樟子松人工林的科学经营提供科学依据。

【方法】

利用长期监测样地，对不同间伐强度下的樟子松人工林的胸径、材积、林分蓄积及物种多样性进行了研究。

【结果】

抚育间伐3 a后，间伐林分单木的胸径、材积的年均生长量均显著高于对照，低（LT，保留密度为2 000株/hm²）、中（MT，保留密度为1 667株/hm²）、高（HT，保留密度为1 333株/hm²）3种间伐强度的胸径年生长量较对照（CK，密度为3 200～3 425株/hm²）分别增加了22.22%、48.15%和81.48%；材积年生长量则较对照分别提升了58.00%、72.00%和130.00%；间伐改变了林分的径级分布，使林分的径级结构从正态分布向对数正态分布转化；间伐林分的蓄积年生长量均低于对照，但未达到显著水平，而林分蓄积生长率则高于CK，且HT、MT与对照之间达到了显著水平（P<0.05），HT、MT和LT的蓄积生长率较CK分别提升了38.02%、23.37%和2.97%。间伐明显提升了林下植物的生物量和物种数量，HT、MT和LT 3种处理下的林下生物量较对照提升了123.53%、94.12%和35.29%，物种数量分别提升了46.67%、70.00%和36.67%；Simpson指数、Shannon指数和Margalef指数随间伐强度的增加而增加，但各处理间差异未达到显著水平，林下植物生物量较物种多样性对抚育间伐更为敏感。

【结论】

间伐明显提升了塞罕坝地区樟子松人工林的胸径和单株材积的生长量、林分蓄积生长率，以及林下植物的生物量和物种数量。综合抚育间伐对林分生长及多样性的影响来看，当前塞罕坝地区樟子松人工林的适宜抚育强度为高强度，即保留密度1 333株/hm²。

【Objective】

The aim of this study is to understand the effects of thinning intensity on the growth and plant species diversity of Pinus sylvestris var. mongholica plantation in Saihanba area, and provide scientific basis for the scientific and reasonable management of the plantations.

【Method】

Based on the on long-term monitoring plots, the DBH, volume, stand stock and species diversity of Pinus sylvestris var. mongholica plantations under different thinning intensities were studied.

【Result】

After 3 years of tending thinning, the average annual growth of DBH (Diameter at breast height) and volume of each tree was significantly higher than that of CK, and the average annual growth of DBH of low (LT, 2 000 plant/hm²), medium (MT, 1 667 plant/hm²) and high (HT, 1 333 plant/hm²) thinning intensity increased by 22.22%, 48.15% and 81.48%, respectively, compared with CK (3 200-3 425 plant/hm²). The annual growth of volume was increased by 58.00%, 72.00% and 130.00%, respectively. Thinning changed the DBH class distribution of the stand, which changed from normal to lognormal. The annual growth of stock of the thinning forests was lower than that of CK, but did not reach a significant level (P>0.05), and there was a significant level between HT, MT and the control (P<0.05) in the annual growth rate, which were increased by 38.02%, 23.37% and 2.97% for HT, MT and LT respectively, compared with CK. The biomass of HT, MT and LT increased by 123.53%, 94.12% and 35.29% compared with CK, and the species number increased by 46.67%, 70.00% and 36.67%, respectively. The Simpson index, Shannon index and Margalef index increased with the increase of thinning intensity, but the differences among them did not reach a significant level; the biomass of understory plants was more sensitive to tending thinning than species diversity.

【Conclusion】

Thinning obviously promotes the growth of DBH, individual tree volume, growth rate of forest stock, as well as the biomass and species number of understory plants; considering the impact on the growth and diversity of the stand, the current suitable tending intensity is HT, under which the density is about 1 333 trees/hm².
