为了研究森林抚育对森林资源变化和生态状况的影响，对红松中龄林抚育成效进行了分析，通过对监测样地与对照样地林分分析，结果表明：抚育间伐降低了林分密度，调整了林分结构，改善了林内环境条件，促进了林木及林下植物生长，使林木树高、公顷蓄积量、植被盖度均有所增加。与对照相比，抚育间伐的林分土壤的酸碱性无明显差异；监测区林分表层土壤的容重减小，非毛管孔隙度、毛管孔隙度、总孔隙度增加，使表层土壤的疏松程度、通气透水性及持水能力增强；但由于抚育时间较短，对林木胸径、下层土壤的疏松程度和持水能力影响还不是很明显。

In order to study effect of forest tending management on changes of forest resources and ecological condi‐tions ,effect of tending for middle‐aged forest of Pinus koraiensis were analyzed .The stand of monitoring plot and control plot were analyzed .Result shows that forest tending reduces stand density ,adjusts stand structure ,improves forest environment ,promotes the grow th of trees and understory plant ,and increases the forest tree height ,ha stock and vegetation cover .Compared with the control ,the soil pH in the tending forest shows no significant difference;the soil bulk density of stand surface in monitoring area decreases ,the non‐capillary porosity ,capillary porosity and total porosity increases ,which reinforces the loose degree of surface soil ,air permeability and water holding capacity . However ,the impact on DBH of tree ,the loose degree of subsoil and water holding capacity is not very obvious due to the short time tending .
