Abstract:

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.
