摘要:
森林经营管理影响植物-土壤系统碳氮磷元素转化及其计量关系。在浙江开化县林场开展了不同间伐强度下凋落物和土壤碳氮磷储量及其生态化学计量关系研究。结果表明,间伐7 年后,凋落物生物量及碳氮磷储量在不同间伐处理之间没有显著差异,土壤总有机碳、易氧化有机碳、总磷和有效磷储量在不同间伐处理之间的差异也不显著,但中度间伐处理土壤总氮和水解氮储量比未间伐处理分别增加了40.7%和32.3%,轻度间伐处理与未间伐处理之间土壤总氮和水解氮储量差异不显著。凋落物和土壤碳氮磷生态化学计量比在不同间伐处理之间差异不显著,但土壤易氧化有机碳/水解氮随间伐强度增大逐渐降低(50.1 ~ 35.9),水解氮/有效磷随间伐强度增大逐渐增加(60.0 ~ 81.6)。因此,间伐有利于土壤氮素的积累,这可能与间伐后凋落物生物量的增加有关。
Abstract:
In 1996, improved Cunninghamia lanceolata families were afforested with density of 2500 individual/ha in Kaihua Forest Farm of Zhejiang province.Tendering was carried out 2 times/year in the first 3 years after planting.In 2003, the first thinning was implement and in 2010, the second thinning experiment was made with light intensity (18%), moderate intensity (32%) and control (no thinning) in sample plot of 20 m×20m with 3 repeats.Within sample plot, 5 quadrats were established.In 2017, litter and soil in different quadrat were collected for investigation.The results showed that litter biomass, carbon, nitrogen and phosphorus storages had no significant difference among different treatment.The storage of total soil organic carbon, readily oxidizable organic carbon, total phosphorus and available phosphorus showed the same.However, the storage of total and hydrolysable nitrogen in the plot with moderate intensity increased by 40.7% and 32.3%than that in the control.There was no significant difference of total and hydrolysable nitrogen between light thinning and the control.The C:N:P ratios in litter and soil had no significant difference among different thinning treatment, while the ratio of soil readily oxidizable organic carbon/hydrolysable nitrogen decreased with the increase of thinning intensity (from 50.1 to 35.9), and the ratio of hydrolysable nitrogen/available phosphorus increased with the thinning intensity (from 60.0 to 81.6).
