摘　　要：笔者在中条山国有林管理局中村林场,研究了目标树近自然经营模式、传统分级法经营模式、目标树全林分经营模式3种不同经营模式对油松纯林生长的影响。结果表明,目标树近自然经营样地伐后平均胸径降低0.5 cm,平均树高降低0.2 cm;目标树全林分经营样地伐后平均胸径提升0.1 cm;平均树高降低0.1 cm;传统分级法经营样地伐后平均胸径提升1.3 cm,平均树高提升0.5 cm;传统分级法经营样地的薪材出材量较高,目标树近自然经营样地的非规格材出材量及收入较高。因此,森林经营模式应根据林分的具体情况和需求来确定。Effect of 3 different management modes such as target tree close-to-nature management mode,traditional grading method management mode and target tree whole-stand management mode on the growth of pure Pinus tabuliformis forest was studied in Zhongcun forest farm of National Forest Administration Bureau of Zhongtiao Mountain.Results showed that in the sample plot of target tree close-to-nature management mode,the average DBH decreased by 0.5 cm and the average tree height decreased by 0.2 cm.In the sample plot of target tree whole-stand management mode,the average DBH increased by 0.1 cm and the average tree height decreased by 0.1 cm.In the sample plot of traditional grading method management mode,the average DBH increased by 1.3 cm and the average tree height increased by 0.5 cm.The output of fuelwood was higher in the sample plot of traditional grading method management mode,while the output of non-standard wood and income were higher in the sample plot of target tree close-to-nature management mode.Therefore,the forest management mode should be determined according to the specific situation and demand of forest stand.
