2013年在黑龙江省内朗乡、友好、大海林以及东方红林业局中布设24块大小为20m×30m的矩形样地。其中:12块样地不采取抚育措施、保持自然生长,作为对照样地组;另外12块样地为抚育样地,采取相应的森林抚育措施作为抚育样地组。2016年对2组样地进行复测。分别采取时间序列横向对比法及组内纵向对比法,分析评价森林抚育措施对森林综合成效监测的影响及相同抚育措施对不同立地类型下森林综合成效的影响。结果表明:1)各抚育样地的林分材积生长量、年均固碳释氧量、生物量年均增长量以及生物多样性增长值均大各对照样地;2)不同立地类型的林分在相同抚育措施下,抚育成效差异性较大。

In 2013,24 rectangular plots with the size of 20m×30m were laid in Neilang Township,Youhao,Dahai Forest and Dongfanghong Forestry Bureau of Heilongjiang Province.Among them,12 plots were treated as control plots without tending measures and maintaining natural growth.The other 12 plots were tending plots,and the corresponding forest tending measures were taken as tending plots group.The two groups of plots were retested in 2016.To analyze and evaluate the effects of forest tending measures on the monitoring of comprehensive forest effectiveness and the effects of the same tending measures on the comprehensive forest effectiveness under different site types,the time series horizontal comparison method and the intra-group longitudinal comparison method were used,respectively.The results showed as follows: 1) The average volume growth,average annual carbon sequestration and oxygen release,average annual biomass growth and biodiversity growth values of each tending plot were higher than those of the control plots.2) Under the same tending measures,the tending effects of stands of different site types were quite different.
