摘要：

为了揭示呼伦贝尔沙地樟子松（Pinus sylvestris var. mongolica）枯落物和土壤C、N、P化学计量特征及其主要驱动因素。以不同龄组（中龄林、近熟林、成熟林）樟子松人工林和天然林为研究对象，分析枯落物和土壤C、N、P化学计量特征，并探究其与土壤因子间的相关关系。结果表明:（1）分解程度显著影响枯落物C、N、P和C:N（P<0.05），土层显著影响土壤N、C:N、C:P（P<0.05），林龄及其与分解程度、土层的交互作用对枯落物和土壤C、N、P化学计量特征无显著影响（P>0.05）。天然林与人工林枯落物和土壤C、N含量和C:P、N:P存在显著差异（P<0.05）。（2）枯落物C含量与枯落物N、P含量呈显著正相关（P<0.05），枯落物C:P与C:N呈显著正相关（P<0.05）；土壤C:P与土壤N:P、C:N呈显著正相关（P<0.05）。（3）枯落物C、N、P化学计量特征主要受pH、磷酸酶和脲酶的显著影响（P<0.05），土壤C、N、P化学计量特征主要受pH、磷酸酶和转化酶的显著影响（P<0.05）。呼伦贝尔沙地樟子松林生长可能受氮限制，而枯落物分解可能受磷限制；枯落物和土壤C、N、P化学计量特征的主要驱动因子分别为pH和磷酸酶。研究结果对樟子松人工林经营管理具有指导意义。

Abstract:

To reveal the characteristics of litter and soil C, N, and P stoichiometry and their main driving factors in the Hulunbuir Sandy Land. Different ages of Pinus sylvestris var. mongolica plantation forests and natural forests (medium-mature, near-mature, and mature forests) were used as research subjects to analyze the characteristics of litter and soil C, N, and P stoichiometry and their correlation with soil factors was explored. (1) The degree of decomposition significantly affected litter C, N, P, and the C:N ratio (P<0.05) and the soil layer significantly affected soil N and C:N and C:P ratios (P<0.05); however, the stand age of the forest and its interactions with the degree of decomposition and soil layer did not have a significant effect on litter and soil C, N, and P stoichiometric characteristics (P>0.05). There were significant differences (P<0.05) between natural and plantation forests in litter and soil relating to C and N contents and C:P and N:P ratios. (2) Litter C content was significantly and positively correlated with litter N and P content (P<0.05), and the litter C:P ratio was significantly and positively correlated with the C:N ratio (P<0.05); the soil C:P ratio was significantly and positively correlated with the soil N:P and C:N ratios (P<0.05). (3) The C, N, and P stoichiometric characteristics of litter were mainly significantly affected by pH, phosphatase, and urease (P<0.05), and the soil C, N and P stoichiometric characteristics were mainly significantly affected by pH, phosphatase, and convertase (P<0.05). The growth of P. sylvestris var. mongolica forest in the Hulunbuir Sandy Land may be limited by nitrogen, whereas the decomposition of litter may be limited by phosphorus; the main drivers of litter and soil C, N, and P stoichiometric characteristics were pH and phosphatase, respectively. This improved information is of great significance for guiding the management of P. sylvestris var. mongolica forests.
