摘要: 为了阐明择伐面积对群状择伐后所栽植幼树碳储量的影响及择伐与人工更新共同作用对华北落叶松低效林林下灌草、枯落物碳储量的影响,对0.02,0.03,0.05hm2孔隙内人工栽植的幼树,以及林下灌草和枯落物碳储量的变化规律进行研究。结果表明:对于生物量来讲,人工更新栽植的华北落叶松生物量随着择伐孔面积的增大而增加,人工更新栽植的白桦生物量在面积为0.03hm2时达最大值;同一树种不同择伐面积下,当择伐面积为0.03hm2时,灌木生物量达到最大;不同择伐面积下,栽植华北落叶松择伐孔内草本生物量均高于白桦;随着择伐孔面积的增大,枯落物的生物量逐渐减少,且白桦样地内的枯落物生物量较高。对于碳储量来讲,栽植同一树种的样地内,随着群状择伐孔径的增加,白桦样地碳储量呈递减趋势,而华北落叶松则为先增加后减少趋势。同一择伐面积下,栽植华北落叶松的样地总碳储量均较白桦高,且当择伐孔面积为0.03hm2时,栽植华北落叶松的样地总碳储量最大。

Abstract: In order to expound the influence of gap area on carbon reserve of planted saplings as well as influence of selective cutting and artificial regeneration on carbon reserve of shrubbery,grasses and litter of Larix principis-rupprechtii Mayr.low efficiency stands,the changing rule of carbon storage about sapling,shrub-grass and litter within the holes of 0.02hm2,0.03hm2 and 0.05hm2 were investigated.The results showed that,for biomass,artificially planted larix pricipis-rupprechtii biomass increased with the increase of selective pore area,artificially planted Betula platyphylla reaches maximum value in the area of 0.03 hm2.When selective hole covers an area of 0.03 hm2,shrub biomass reached maximum.In different selective areas,the herb biomass of selective cutting hole with planting Larix principis-rupprechtii Mayr.was higher than Betula platyphylla.Along with the rising of the selective cutting hole area,the litter biomass reduced gradually,and the litter biomass within the hole planting Betula platyphylla was higher.For carbon storage,within the hole of same planted tree species,with the increase of the area of selective cutting hole,carbon storage of Betula platyphylla sample plot showed a trend of decreasing,while Larix principis-rupprechtii Mayr.sample plot showed the carbon storaye climbs up and then declines.In the same selective cutting area,planted Larix principis-rupprechtii Mayr.’s total carbon storage was relatively higher than Betula platyphylla.When selective cutting hole covers an area of 0.03 hm2,the sample area’s total carbon storagesof planted Larix principis-rupprechtii Mayr was maximum.
