摘要土壤碳（C）、氮（N）和磷（P）浓度在调节植物生长和养分循环方面发挥着关键作用，研究其储量对于深入理解森林生态系统功能和可持续经营管理有重要意义。沙地樟子松（Pinus sylvestris var.mongolica）是我国北方防风固沙的优良树种，由于种植地区和年限不同，其土壤碳氮磷储量可能存在差异。为揭示引种地区和林龄对沙地樟子松林土壤碳氮磷储量分布的影响，以呼伦贝尔沙地、科尔沁沙地和毛乌素沙地不同龄组（中龄、近熟和成熟）樟子松人工林为研究对象，测算土壤碳氮磷质量分数和储量，采用方差分析比较储量差异性并阐明其与环境因子的相关性。结果表明：1）研究区沙地樟子松人工林土壤有机碳、氮、磷储量分别为1.78~34.38、0.33~2.09和0.48~1.83 kg/m²；2）引种地区对土壤碳氮磷储量均有显著影响（P<0.05），林龄对土壤碳氮储量影响显著（P<0.05）；随着林龄的增加，碳储量先增加后减小，氮储量呈逐渐增加的趋势；3）土壤碳氮储量与孔隙度、蔗糖酶和磷酸酶呈正相关关系，与平均降水量、pH、温度等呈负相关关系；氮磷储量间存在显著负相关关系（P<0.05），磷储量与环境因子的相关关系与氮储量相反。引种地区和林龄对沙地樟子松土壤碳氮储量影响显著，而磷储量受引种地区和氮储量影响较大，对沙地樟子松人工林经营管理可适当施加磷肥并注重对成熟林的管护。

Abstract：[Background] Soil carbon (C), nitrogen (N) and phosphorus (P) play a key role in plant growth regulation and nutrient cycling. Studying forest C, N and P storage is of great significance for in-depth understanding of forest ecosystem functions and sustainable management. Pinus sylvestris var. mongolica is a practical tree species for desertification combating, and soil and water conservation in northern China. Due to the different introduced regions and years, there may be differences in C, N and P storage of P. sylvestris var. mongolica plantations. To reveal the effects of introduced region and stand age on C, N and P storage in P. sylvestris var. mongolica plantations.[Methods] Field investigation and sample collection were conducted in different age groups (middle-aged, near-mature and mature) plantations in the Hulunbuir, Horqin and Mu Us Sandy Land. Soil samples from were collected in 0-20 and 20-40 cm layers, and the C, N and P contents and storage were measured. The difference of C, N and P storage in different regions with different ages were analyzed by ANOVA, and their correlations with environmental factors were also clarified by Person correlation analysis.[Results] 1) C, N and P storage of P. sylvestris var. mongolica plantations were 1.78-34.38, 0.33-2.09,and 0.48-1.83 kg/m², respectively. 2) The introduced region had a significant impact on C, N and P storages (P<0.05) and the stand age had a significant impact on C and N storage (P<0.05) With increasing stand age, C storage first increased and then decreased, N storage increased. 3) C and N storage were positively correlated with soil porosity, invertase and phosphatase activity, and negatively correlated with average precipitation, soil pH and temperature. A significant negative correlation was obtained between N and P storage (P<0.05), and they both had the strongest correlation with soil porosity. The correlation between P storage and environmental factors was opposite to that of N storage.[Conculsions] C and N storage of P. sylvestris var. mongolica plantations are significantly affected by the introduced region and stand age, while P storage is greatly affected by the introduced region and nitrogen storage. P is the important limiting factor for the growth of P. sylvestris var. mongolica plantations on sandy land. It is recommended that the regional environmental differences should be considered in management of P. sylvestris var. mongolica plantation, phosphate fertilizers can be applied appropriately and we should pay attention to the management and protection of mature forests. This improved information provides a theoretical basis for the sustainable management of P. sylvestris plantation.
