摘要
[目的]近自然经营方式对旺业甸不同林龄油松人工林碳储量的影响进行研究,为该地区油松人工林制定合理的森林经营方式提供理论支持。[方法]以内蒙古自治区赤峰市喀喇沁旗旺业甸林场近自然经营条件下的油松人工幼龄林、中龄林、近熟林为研究对象,以常规经营和未经营作为对照,对油松人工林碳储量开展了比较研究。[结果](1)植被、乔木和枯落物碳储量表现为:未经营>近自然经营>常规经营,虽然近自然经营的低于未经营的,但是高于常规经营的,近自然经营相对于常规经营来看,有利于碳储量的增加。(2)林下草本层碳储量表现为:近自然经营>常规经营>未经营,近自然经营有效的改变了林分结构,促进了草本植物的生长和碳汇量的增加;(3)林下灌木层碳储量而言,由于林下灌木种类少,株数低等因素的影响,其碳储量无显著性规律。[结论]总体来看,如果从增加森林碳汇方面考虑,未经营利于森林碳汇的积累;常规经营更有利于提高森林木材质量,如果两方面都考虑,近自然经营方式是最适合的。
[Objective]The effects of natural alike management on carbon storage in Pinus tabulaeformis plantations under different forest ages were studied in order to provide theoretical support for establishing reasonable forest management mode in Pinustabulaeformis plantation.[Methods]This article took the young,middle-aged and near-mature Pinus tabulaeformis planted forest under natural alike management as example,and compared it with the forests under conventional management and no treatment,studied the carbon storage of the artificial Pinus tabulaeformis forest at Wangyedian forest farm of Chifeng City,Inner Mongolia.[Results]（1）The carbon storages of vegetation,trees and litters were ranked as follow：values of the no treatment〉the ones of natural alike management〉the ones of conventional management.Althoughthe carbon storage of natural alike forest management was lower than those of no treatment,but was higher than those of conventional management.It was benefit for the increase of carbon storage.（2）Carbon storage of herbs had the following rank：values of natural alike management〉the ones of conventional management〉the ones of no treatment.The natural alike management effectively improve the forest structure,and helped herbaceous grow well and hence carbon storage increased.（3）Because there were few species and densities of shrubs were low,on obvious regularity with respect to the carbon storage of shrub layer of these forests was found.[Conclusion]On the whole,if we consider the increase of forest carbon storage,it is conducive for the no treatment in term of the accumulation of forest carbon storage;the conventional management is more conducive for improving the quality of forest timber;if both aspects are considered,the natural alike management is the most appropriate one.
