近自然森林经营对华北落叶松人工林林分结构和林下植被的影响
Effect of Close-to-nature Forest Management on Stand Structure of Larix principis-rupprechtii Plantation and Underground Vegetation
摘要
Abstract
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.关键词
