【Objective】

To explore the effects of stand types on plant diversity and soil stoichiometric characteristics, and to provide theoretical references for afforestation and vegetation restoration and reconstruction in arid and semi-arid regions.

【Method】

In this study, Pinus tabuliformis×Cotinus coggygria (Pt×Cc), Pinus tabuliformis×Quercus mongolica (Pt×Qm), Pinus tabuliformis×Caragana korshinskii (Pt×Ck), Pinus tabuliformis×Prunus sibirica (Pt×Ps), Pinus tabuliformis×Acer mono (Pt×Am) and Pinus tabuliformis (Pt) were selected as the research objects. Based on the investigation of typical plots and the results of indoor experiments, the understory diversity and contents, stocks and stoichiometric ratios of soil organic carbon (SOC), total nitrogen (TN) and total phosphorus (TP) in the soil were calculated.

【Result】

Stand types significantly influence the composition and diversity characteristics of understory shrubs and herbs. The understory plant species are as follows: Pt×Qm (39 species), Pt×Ck (38 species), Pt×Cc (27 species), Pt×Ps (27 species), Pt (21 species), and Pt×Am (20 species). The dominant species in the shrub layer consist primarily of regenerating saplings from the mixed tree species, while the herb layer is co-dominated by Lespedeza bicolor and Carex lanceolata. In the shrub layer, the plant diversity index of the Pt×Qm was significantly higher than that of other stands. The plant richness of Pt is the lowest, but the evenness index is relatively high. In the herb layer, the Pt×Ck exhibited the highest plant diversity index, while the Pt showed a relatively high plant diversity index with no significant difference compared to most other forest stands. The content and stocks of SOC and TN in mixed forests were significantly higher than those in pure forests, and there was no significant difference in TP content and stocks. The soil C∶N of Pt×Qm and Pt×Cc showed no significant differences compared to Pt, while their soil C∶P and N∶P were significantly higher than that of Pt. The comprehensive scores of the six stand types were ranked as follows: Pt×Qm>Pt×Cc>Pt×Ck>Pt×Ps>Pt×Am>Pt.

【Conclusion】

Introducing broadleaf tree species into Pt can enhance understory plant diversity and promote soil nutrient retention. The Pt×Qm demonstrates optimal performance in terms of species diversity and soil nutrient content, making it an ideal configuration for ecological restoration efforts.

【目的】

探讨林分类型对植物多样性和土壤化学计量特征的影响,为干旱、半干旱地区人工林营造及植被恢复与重建提供理论参考。

【方法】

选择油松黄栌混交林、油松蒙古栎混交林、油松柠条混交林、油松山杏混交林、油松五角槭混交林和油松纯林为研究对象,通过典型样地调查及室内实验,计算林下植物多样性指数、土壤有机碳(SOC)、全氮(TN)、全磷(TP)含量和储量及化学计量比。

【结果】

林分类型显著影响林下灌草植物组成及多样性特征。林下植物种数依次为油松蒙古栎混交林(39种)、油松柠条混交林(38种)、油松黄栌混交林(27种)、油松山杏混交林(27种)、油松纯林(21种)和油松五角槭混交林(20种);灌木层以混交树种的更新为主要优势种;草本层以胡枝子和亚柄薹草为共同优势种。灌木层,油松蒙古栎混交林植物多样性指数显著高于其他林分;油松纯林植物丰富度最低,但均匀度指数较高。草本层,油松柠条混交林植物多样性指数最高,油松纯林植物多样性指数与多数林分无显著差异。油松混交林的SOC、TN含量和储量显著高于纯林,TP含量和储量无显著差异。油松蒙古栎混交林和油松黄栌混交林的土壤C∶N与油松纯林相比无显著差异,C∶P和N∶P均显著高于油松纯林。主成分分析结果表明,6种林分类型综合得分依次为油松蒙古栎混交林>油松黄栌混交林>油松柠条混交林>油松山杏混交林>油松五角槭混交林>油松纯林。

【结论】

油松纯林引入阔叶树种有利于林下植物多样性的增加和土壤养分固持。其中油松蒙古栎混交林在物种多样性、土壤养分含量等方面表现最佳,是生态修复中的理想配置。

【目的】

探讨林分类型对植物多样性和土壤化学计量特征的影响,为干旱、半干旱地区人工林营造及植被恢复与重建提供理论参考。

【方法】

选择油松黄栌混交林、油松蒙古栎混交林、油松柠条混交林、油松山杏混交林、油松五角槭混交林和油松纯林为研究对象,通过典型样地调查及室内实验,计算林下植物多样性指数、土壤有机碳(SOC)、全氮(TN)、全磷(TP)含量和储量及化学计量比。

【结果】

林分类型显著影响林下灌草植物组成及多样性特征。林下植物种数依次为油松蒙古栎混交林(39种)、油松柠条混交林(38种)、油松黄栌混交林(27种)、油松山杏混交林(27种)、油松纯林(21种)和油松五角槭混交林(20种);灌木层以混交树种的更新为主要优势种;草本层以胡枝子和亚柄薹草为共同优势种。灌木层,油松蒙古栎混交林植物多样性指数显著高于其他林分;油松纯林植物丰富度最低,但均匀度指数较高。草本层,油松柠条混交林植物多样性指数最高,油松纯林植物多样性指数与多数林分无显著差异。油松混交林的SOC、TN含量和储量显著高于纯林,TP含量和储量无显著差异。油松蒙古栎混交林和油松黄栌混交林的土壤C∶N与油松纯林相比无显著差异,C∶P和N∶P均显著高于油松纯林。主成分分析结果表明,6种林分类型综合得分依次为油松蒙古栎混交林>油松黄栌混交林>油松柠条混交林>油松山杏混交林>油松五角槭混交林>油松纯林。

【结论】

油松纯林引入阔叶树种有利于林下植物多样性的增加和土壤养分固持。其中油松蒙古栎混交林在物种多样性、土壤养分含量等方面表现最佳,是生态修复中的理想配置。

【Objective】

To explore the effects of stand types on plant diversity and soil stoichiometric characteristics, and to provide theoretical references for afforestation and vegetation restoration and reconstruction in arid and semi-arid regions.

【Method】

In this study, Pinus tabuliformis×Cotinus coggygria (Pt×Cc), Pinus tabuliformis×Quercus mongolica (Pt×Qm), Pinus tabuliformis×Caragana korshinskii (Pt×Ck), Pinus tabuliformis×Prunus sibirica (Pt×Ps), Pinus tabuliformis×Acer mono (Pt×Am) and Pinus tabuliformis (Pt) were selected as the research objects. Based on the investigation of typical plots and the results of indoor experiments, the understory diversity and contents, stocks and stoichiometric ratios of soil organic carbon (SOC), total nitrogen (TN) and total phosphorus (TP) in the soil were calculated.

【Result】

Stand types significantly influence the composition and diversity characteristics of understory shrubs and herbs. The understory plant species are as follows: Pt×Qm (39 species), Pt×Ck (38 species), Pt×Cc (27 species), Pt×Ps (27 species), Pt (21 species), and Pt×Am (20 species). The dominant species in the shrub layer consist primarily of regenerating saplings from the mixed tree species, while the herb layer is co-dominated by Lespedeza bicolor and Carex lanceolata. In the shrub layer, the plant diversity index of the Pt×Qm was significantly higher than that of other stands. The plant richness of Pt is the lowest, but the evenness index is relatively high. In the herb layer, the Pt×Ck exhibited the highest plant diversity index, while the Pt showed a relatively high plant diversity index with no significant difference compared to most other forest stands. The content and stocks of SOC and TN in mixed forests were significantly higher than those in pure forests, and there was no significant difference in TP content and stocks. The soil C∶N of Pt×Qm and Pt×Cc showed no significant differences compared to Pt, while their soil C∶P and N∶P were significantly higher than that of Pt. The comprehensive scores of the six stand types were ranked as follows: Pt×Qm>Pt×Cc>Pt×Ck>Pt×Ps>Pt×Am>Pt.

【Conclusion】

Introducing broadleaf tree species into Pt can enhance understory plant diversity and promote soil nutrient retention. The Pt×Qm demonstrates optimal performance in terms of species diversity and soil nutrient content, making it an ideal configuration for ecological restoration efforts.
