摘要：为给北京地区华北落叶松(Larix principis-rupprechtii)人工林可持续经营提供理论依据,以北京京西林场斋堂山45年生华北落叶松人工林为研究对象,分析近自然森林经营对林分胸径、树高和蓄积量及林下植被组成和天然更新的影响。结果表明,在近自然森林经营样地中,林木胸径分布曲线为近正态分布曲线,树高分布曲线为单峰偏右曲线,与对照相比,峰值向更高树高方向移动。中和大径木占比均较高,树高14~16 m林木占比均较高。近自然森林经营短时间内使林分总蓄积量下降,但促进中和大径木生长,提高中和大径木蓄积量占比。近自然森林经营样地的灌木和草本植物在科、属和种层面上均有一定程度上升,喜光植物重要值总体上升,耐荫植物重要值总体下降。
In order to provide theoretical basis for sustainable management of Larix principis-rupprechtii planta?tions in Beijing,taking 45-year-old L.principis-rupprechtii plantation in Zhaitangshan of Jingxi forest farm,Beijing as research object,effect of close-to-nature forest management on DBH,tree height and stand volume as well as underground vegetation composition and natural regeneration were analyzed.Results showed that in close-to-nature forest management sample plot,DBH distribution curve of trees were closed to normal distribu?tion curve,while tree height distribution curve exhibited right-skewed curve with peak shifted towards higher tree heights compared with control.Proportions of medium and large diameter trees and trees with heights of 14-16 m were higher.Close-to-nature forest management temporarily reduced total volume,while it promoted growths of medium and large diameter trees and increased their volume proportions.Species number of shrubs and herbs in close-to-nature forest management sample plot increased at family,genus and species levels,with overall rising in importance values of light-preferring plants and declining in shade-tolerant species.
