【Objective】

To provide theoretical and technical support for the sustainable management and soil fertility maintenance of larch plantations.

【Method】

Larix olgensis plantations with basically the same site conditions were selected. In 2018, selective cutting operations with different intensities (25%, 35% and 45%) were carried out according to the stock volume, and non-selective cutting was set as the control. Subsequently, three fixed sample plots were set up in the stands with different selective cutting intensities. In August 2023, after five years of selective cutting operation, the coverage thickness, standing stock, soil physical and chemical properties of litters were measured in each plot. Through single factor analysis of variance, Mantel analysis and structural equation modeling, the changes of litter cover thickness, standing stock and soil physical and chemical properties under different selective cutting intensities and their relationships were studied.

【Result】

After 5 years of selective cutting, the litter cover thickness decreased by 17.4%, 30.3%, and 31.0% at 25%, 35% and 45% selective cutting intensities, respectively, compared to the control stand. The undecomposed litter layer thickness decreased by 32.7% and 36.1% at 35% and 45% selective cutting intensities, respectively, compared to the control stand. The semi-decomposed litter layer thickness decreased by 25.7%,44.2%, and 43.4% at 25%,35%, and 45% selective cutting intensities, respectively, compared to the control stand. High-intensity selective cutting (45%) significantly reduced soil bulk density in the 0-10 cm layer by 17.7% compared to the control. Moderate-intensity selective cutting (35% and 25%) also reduced soil bulk density in the 20-40 cm layer, with reductions of 15.0% and 11.0% respectively. Soil moisture content increased by 40.8% (0-10 cm), 21.8% (10-20 cm), and 18.7% (20-40 cm) after high-intensity selective cutting compared to the control. The maximum soil compaction degree in 0-40 cm soil layer was 785.0 kPa in control forest,724.4 kPa in 25% selective cutting forest, 525.6 kPa in 45% selective cutting forest and 503.9 kPa in 35% selective cutting forest. Under the moderate selective cutting (35%), the soil pH, total nitrogen, total phosphorus, organic carbon and hydrolyzable nitrogen in the 0-10 cm soil layer increased by 5.5%, 21.7%, 39.8%, 45.4% and 51.3% respectively compared with the control. Under the high intensity (45%) selective cutting, the contents of available potassium and available phosphorus in the 0-10 cm soil layer increased by 30.0% and 60.4% respectively compared with the control. The results of structural equation modeling showed that selective cutting had a significant positive effect on soil moisture content and soil chemical properties, and a significant negative effect on soil bulk density, litter cover and litter stock, and also had a significant negative effect on soil chemical properties through changing litter cover and litter stock.

【Conclusion】

Selective cutting management can significantly reduce the accumulation of litter on the surface of forest land, improve the microenvironment in the stand, and be beneficial to the decomposition of litter such as larch needles on the surface. After selective cutting with medium and high intensity (35%, 45%), it can accelerate the decomposition of litter, effectively promote the circulation of soil nutrients, and play an important role in maintaining soil fertility and preventing soil acidification.

【目的】

明确择伐强度、凋落物现存量与土壤理化性质间的关联,为落叶松人工林的可持续经营及土壤肥力维持提供理论与技术支撑。

【方法】

选取立地条件基本一致的长白落叶松人工林,于2018年按蓄积量进行了不同强度(25%、35%、45%)的择伐作业,并设置未择伐为对照,随后在各择伐强度的林分内分别设置了3块固定样地,于择伐经营5 a后的2023年8月,在各样地内对凋落物的覆盖厚度和现存量、土壤理化性质进行调查,通过单因素方差分析、Mantel分析和结构方程模型构建,对不同择伐强度下凋落物覆盖厚度、现存量及土壤理化性质的变化和其相互间的关系进行研究。

【结果】

择伐经营5 a后,25%、35%、45%择伐强度下凋落物覆盖厚度与对照林分相比分别减小17.4%、30.3%、31.0%;未分解层厚度仅在35%、45%择伐强度下与对照林分相比分别减小32.7%、36.1%;半分解层厚度在25%、35%、45%择伐强度下与对照林分相比分别减小25.7%、44.2%、43.4%。高强度择伐(45%)对0~10 cm土层的土壤容重影响较大,与对照组相比减小17.7%;中弱强度择伐(35%、25%)对20~40 cm土层的土壤容重影响较大,与对照林分相比分别减小15.0%、11.0%。土壤含水率在高强度(45%)的择伐后较对照林分分别增大40.8%(0~10 cm)、21.8%(10~20 cm)、18.7%(20~40 cm)。0~40 cm土层中土壤紧实度最大值在不同择伐强度下表现从大到小依次为对照林分(785.0 kPa)、25%择伐强度(724.4 kPa)、45%择伐强度(525.6 kPa)、35%择伐强度(503.9 kPa)。中等强度的择伐(35%)下,0~10 cm土层土壤pH值和全氮、全磷、有机质碳、水解性氮含量与对照组相比分别提高5.5%、21.7%、39.8%、45.4%、51.3%。高强度(45%)的择伐下,0~10 cm土层土壤速效钾、速效磷含量与对照组相比分别提高30.0%、60.4%。通过结构方程模型拟合结果发现,择伐经营可以直接对土壤含水率、土壤化学性质产生显著的正向影响,对土壤容重、凋落物覆盖厚度、凋落物现存量产生显著的负向影响;凋落物覆盖厚度和现存量对土壤化学性质间接产生显著负向影响。

【结论】

择伐经营能显著减少林地表面凋落物堆积,改善林分内微环境,有利于地表落叶松针叶等凋落物的分解。在中高强度(35%、45%)的择伐后,能够加速凋落物的分解,有效促进土壤养分循环,对维持土壤肥力和预防土壤酸化有重要作用。

【目的】

明确择伐强度、凋落物现存量与土壤理化性质间的关联,为落叶松人工林的可持续经营及土壤肥力维持提供理论与技术支撑。

【方法】

选取立地条件基本一致的长白落叶松人工林,于2018年按蓄积量进行了不同强度(25%、35%、45%)的择伐作业,并设置未择伐为对照,随后在各择伐强度的林分内分别设置了3块固定样地,于择伐经营5 a后的2023年8月,在各样地内对凋落物的覆盖厚度和现存量、土壤理化性质进行调查,通过单因素方差分析、Mantel分析和结构方程模型构建,对不同择伐强度下凋落物覆盖厚度、现存量及土壤理化性质的变化和其相互间的关系进行研究。

【结果】

择伐经营5 a后,25%、35%、45%择伐强度下凋落物覆盖厚度与对照林分相比分别减小17.4%、30.3%、31.0%;未分解层厚度仅在35%、45%择伐强度下与对照林分相比分别减小32.7%、36.1%;半分解层厚度在25%、35%、45%择伐强度下与对照林分相比分别减小25.7%、44.2%、43.4%。高强度择伐(45%)对0~10 cm土层的土壤容重影响较大,与对照组相比减小17.7%;中弱强度择伐(35%、25%)对20~40 cm土层的土壤容重影响较大,与对照林分相比分别减小15.0%、11.0%。土壤含水率在高强度(45%)的择伐后较对照林分分别增大40.8%(0~10 cm)、21.8%(10~20 cm)、18.7%(20~40 cm)。0~40 cm土层中土壤紧实度最大值在不同择伐强度下表现从大到小依次为对照林分(785.0 kPa)、25%择伐强度(724.4 kPa)、45%择伐强度(525.6 kPa)、35%择伐强度(503.9 kPa)。中等强度的择伐(35%)下,0~10 cm土层土壤pH值和全氮、全磷、有机质碳、水解性氮含量与对照组相比分别提高5.5%、21.7%、39.8%、45.4%、51.3%。高强度(45%)的择伐下,0~10 cm土层土壤速效钾、速效磷含量与对照组相比分别提高30.0%、60.4%。通过结构方程模型拟合结果发现,择伐经营可以直接对土壤含水率、土壤化学性质产生显著的正向影响,对土壤容重、凋落物覆盖厚度、凋落物现存量产生显著的负向影响;凋落物覆盖厚度和现存量对土壤化学性质间接产生显著负向影响。

【结论】

择伐经营能显著减少林地表面凋落物堆积,改善林分内微环境,有利于地表落叶松针叶等凋落物的分解。在中高强度(35%、45%)的择伐后,能够加速凋落物的分解,有效促进土壤养分循环,对维持土壤肥力和预防土壤酸化有重要作用。

【Objective】

To provide theoretical and technical support for the sustainable management and soil fertility maintenance of larch plantations.

【Method】

Larix olgensis plantations with basically the same site conditions were selected. In 2018, selective cutting operations with different intensities (25%, 35% and 45%) were carried out according to the stock volume, and non-selective cutting was set as the control. Subsequently, three fixed sample plots were set up in the stands with different selective cutting intensities. In August 2023, after five years of selective cutting operation, the coverage thickness, standing stock, soil physical and chemical properties of litters were measured in each plot. Through single factor analysis of variance, Mantel analysis and structural equation modeling, the changes of litter cover thickness, standing stock and soil physical and chemical properties under different selective cutting intensities and their relationships were studied.

【Result】

After 5 years of selective cutting, the litter cover thickness decreased by 17.4%, 30.3%, and 31.0% at 25%, 35% and 45% selective cutting intensities, respectively, compared to the control stand. The undecomposed litter layer thickness decreased by 32.7% and 36.1% at 35% and 45% selective cutting intensities, respectively, compared to the control stand. The semi-decomposed litter layer thickness decreased by 25.7%,44.2%, and 43.4% at 25%,35%, and 45% selective cutting intensities, respectively, compared to the control stand. High-intensity selective cutting (45%) significantly reduced soil bulk density in the 0-10 cm layer by 17.7% compared to the control. Moderate-intensity selective cutting (35% and 25%) also reduced soil bulk density in the 20-40 cm layer, with reductions of 15.0% and 11.0% respectively. Soil moisture content increased by 40.8% (0-10 cm), 21.8% (10-20 cm), and 18.7% (20-40 cm) after high-intensity selective cutting compared to the control. The maximum soil compaction degree in 0-40 cm soil layer was 785.0 kPa in control forest,724.4 kPa in 25% selective cutting forest, 525.6 kPa in 45% selective cutting forest and 503.9 kPa in 35% selective cutting forest. Under the moderate selective cutting (35%), the soil pH, total nitrogen, total phosphorus, organic carbon and hydrolyzable nitrogen in the 0-10 cm soil layer increased by 5.5%, 21.7%, 39.8%, 45.4% and 51.3% respectively compared with the control. Under the high intensity (45%) selective cutting, the contents of available potassium and available phosphorus in the 0-10 cm soil layer increased by 30.0% and 60.4% respectively compared with the control. The results of structural equation modeling showed that selective cutting had a significant positive effect on soil moisture content and soil chemical properties, and a significant negative effect on soil bulk density, litter cover and litter stock, and also had a significant negative effect on soil chemical properties through changing litter cover and litter stock.

【Conclusion】

Selective cutting management can significantly reduce the accumulation of litter on the surface of forest land, improve the microenvironment in the stand, and be beneficial to the decomposition of litter such as larch needles on the surface. After selective cutting with medium and high intensity (35%, 45%), it can accelerate the decomposition of litter, effectively promote the circulation of soil nutrients, and play an important role in maintaining soil fertility and preventing soil acidification.
