摘    要:采用标准地的方式调查不同强度的择伐作业前后常绿阔叶林林分中保留木和幼树幼苗的变化.结果表明:保留木的损伤与采伐木的胸径及择伐强度有关.胸径越大则损伤率越大.择伐强度亦然.择伐作业后幼树的破坏与择伐强度间无明显的关系.这与作业的具体情况有关.择伐后与皆伐未整地经一段时间.林内幼苗数量都有所增加,尤以皆伐作业和弱度择伐为最.

关 键 词:采伐强度  择伐  保留木  幼树幼苗

Abstract:Through surveying of sample plots of harvesting operations in evergreen broadleaved forest, the effect of selective cutting of different intensities to standing timber, young trees and seedlings were analyzed. The results show that: the damage to standing timber is related to DBH and the selection cutting intensities. The larger of DBH and the more intensive of cutting. the more serious of damage. The damage of young trees has no directive relationship to cutting intensities, it may be related to the cutting operation situation. After cutting operations, the amount of seedlings increase to some extent without slash disposal, and clear cutting and low intensity selective cutting demonstrate strongly.
Keywords:intensities  Selective cutting  standing timber  young trees andseedings
