摘　　要：以黑龙江省东方红林业局天然阔叶林和人工针叶林为研究对象,分别设置抚育采伐与对照2种处理,于2013年和2016年对样地进行调查。结果表明:抚育采伐使阔叶林样地辛普森指数和香农-威纳指数分别增加了35.69%和25.49%,使针叶林样地辛普森指数和香农-威纳指数分别增加了73.42%和61.19%;抚育采伐显著提高了阔叶林和针叶林样地林木蓄积量,蓄积量抚育成效分别为3.09%和1.48%;抚育采伐显著提高了阔叶林和针叶林样地生物量,生物量年平均增长率为4.69%和16.97%;抚育采伐使阔叶林样地年均固碳量和年均释氧量分别增加50.17%和59.97%,使针叶林样地年均固碳量和年均释氧量分别增加59.60%和59.37%;抚育样地内生物多样性抚育成效值、蓄积量抚育成效值和生物量抚育成效值均大于0,说明抚育采伐增加了林分的综合效益。The tending thinning and control treatments were set in natural broad-leaved forest and coniferous plantations in Dongfanghong Forestry Bureau,respectively,and the investigation was conducted in 2013 and 2016.The results showed that tending thinning increased the Simpson index and Shannon Weiner index by 35.69%and 25.49%respectively in natural broad-leaved forest,and increased by 73.42%and 61.19%respectively in coniferous plantations.Tending thinning significantly increased the timber volume of broad-leaved forest and coniferous plantations,and the effect of tending thinning was 3.09%and 1.48%,respectively.Tending thinning significantly increased the average annual growth rates of biomass by 4.69%and 16.97%in natural broad-leaved forest and coniferous plantations respectively.Furthermore,tending thinning increased the average annual carbon sequestration and oxygen release of broad-leaved forest by 50.17%and 59.97%respectively,and 59.60%and 59.37%respectively in coniferous plantations.The effect values of tending thinning on biodiversity,timber volume and biomass were all greater than zero,indicating that tending thinning had increased the comprehensive benefits in the both forests.
