摘    要:对秦岭火地塘松栎混交林皆伐迹地天然更新调查结果表明,松栎混交林皆伐后大多数天然更新良好,14~15年的更新幼树数量可达4700~10000株/ha,其中主要乔木树种为3000~4000株/ha,平均树高为2.5~4.0m;皆伐后天然更新状况与保留母树状况、地形、下木生长状况有密切关系;采伐迹地适当保留母树,保护伐前更新幼树。抚育伐后更新林分,可以缩短森林培育周期。

关 键 词:天然更新  皆伐迹地      混交林

Abstract:The investigation on the natural regeneration of oak-pine mixed forest on cutting-blank in Huoditang of Qinling mountain indicated that there are good or better with 4700-10000 younglings per ha and 30004000 arbor-younglings per ha as well as an average height of 2.5-4.0m on the most cutting-blanks, after cutting over the old stands natural regeneration on cutting-blanks is most influenced by the conditions of mother trees, topography, undergrowth, etc. Rational retention of mother trees, protection of younglings from pre-cutting and tending forestcrop from post-cutting can shorten the period of forest management. Oak-pine mixed forest is suitable to small area or strip cutting and the conservation function of water supply by forest for cutting-over should be studied.
Keywords:natural regeneration  cutting-blank  oak-pine mixed forest  Qinling
