摘要/Abstract

摘要： 为探讨灌丛引入对荒漠草原土壤水分、碳氮磷化学计量及其权衡关系的影响，本研究以宁夏东部荒漠草原不同引入年限（8年、17年和27年）的灌丛地和17年封育草地为对象，分析0~100 cm土层的土壤水分、有机碳（SOC）、全氮（TN）、全磷（TP）含量及化学计量比特征，并采用均方根偏差（RMSD）量化土壤水分与养分间的权衡关系。结果表明，随灌丛引入年限增加显著降低了土壤含水量（P<0.05），土壤全氮呈显著增加趋势（P<0.05），土壤全磷呈先增后减趋势，均始终高于封育草地，其中土壤有机碳和全氮具较强耦合关系；氮磷比、碳磷比随土层深度增加呈波动降低趋势。权衡分析表明，封育草地RMSD均值为0.55，灌丛引入后RMSD均值为0.39，伴随土壤水分降低，0~100 cm土壤水分-养分协同效应消失。综上所述，近30年灌丛引入改善了0~100 cm土壤养分含量，但仍保持其化学计量相对稳定，并可能出现水分胁迫。

Abstract: To investigate the effects of shrub introduction on soil moisture， C-N-P stoichiometry， and their trade-off relationships in a desert steppe， this study was conducted in the desert steppe of eastern Ningxia. The research compared sites with shrubs introduced for different durations （8， 17 and 27 years） with a site enclosed for grassland restoration for 17 years. Soil water， soil organic carbon （SOC）， total nitrogen （TN）， total phosphorus （TP） contents， and their stoichiometric ratios in the 0-100 cm soil layer were analyzed. The root mean square deviation （RMSD） was used to quantify the trade-off between soil water and nutrients. The results showed that soil water content significantly decreased with increasing shrub introduction years （P<0.05）. Soil TN showed a significant increasing trend （P<0.05）， while TP initially increased and then decreased； both were consistently higher than those in the enclosed grassland. SOC and TN exhibited a strong coupling relationship. The soil N∶P and C∶P ratios fluctuated and decreased with increasing soil depth. Trade-off analysis revealed that the mean RMSD was 0.55 in the enclosed grassland， compared to 0.39 in the sites of shrub introduction. As soil water decreased， the synergistic effect between soil water and nutrients disappeared in the 0-100 cm layer. In summary， nearly 30 years of shrub introduction improved the nutrient content in the 0~100 cm soil layer while maintaining relatively stable soil stoichiometric ratios. However， water stress might emerge as a consequence.
