以林口林业局不同抚育间伐的红松人工林为研究对象,调查各林分内植物多样性情况,结果显示:红松人工林抚育间伐后林分草本和灌木的种类、密度和平均高以及林下更新都有所增加,可达 50%以上;群落复杂程度较高,物种个体分配比较均匀;林下更新的种类增加 200%以上,更新密度增加 25%以上.抚育间伐对红松人工林的植物多样性有显著影响,抚育强度越大,植物多样性种类越多,群落结构越复杂.该结论为红松人工林近自然经营提供了理论基础,从丰富植物多样性角度建议红松人工林中龄林采用 60%的采伐强度进行抚育间伐.
Species Diversity of Different Tending Intensity in Pinus koraiensis Plantations
Investigated the plant diversity of different thinning Korean pine plantations in Linkou Forestry Bureau.The results showed that:the types,density and average height of herbaceous and shrub species in the Korean pine plantations increased by more than 50%after thinning;The complexity of the community is relatively high,and the distribution of individual species is relatively uniform;The types of understory regeneration have increased by more than 200%,and the regeneration density has increased by more than 25%.Tending thinning has a significant impact on the plant diversity of Korean pine plantations.The higher the tending intensity,the more diverse the plant species and the more complex the community structure.This conclusion provides a theoretical basis for the near natural management of Korean pine plantations.From the perspective of enriching plant diversity,it is recommended that middle-aged Korean pine plantations adopt 60%cutting intensity for nurturing and thinning.
