Abstract

Abstract: In this study,different ecological restoration techniques were used to restore the degraded alpine swamp wetland in Longbao,Yushu. We analyzed the effects of different treatments including spray irrigation (I),grazing prohibition (II),grazing prohibition in spring (III),spray irrigation + grazing prohibition (IV) and spray irrigation + grazing prohibition in spring (V) on the Carbon (C),Nitrogen (N) and Phosphorus (P) stoichiometry of soil and plant in the degraded alpine swamp wetland. The results shows that the treatments of I，IV and V significantly increased soil moisture content (P＜0.05). The treatment I significantly increased soil organic carbon(SOC)content,C∶N and C∶P in 0~30 cm soil which compared with control (VI) (P＜0.05). The treatment IV had a significant effect on the increasing of SOC content and C∶N in 0~30 cm soil. The treatment III significantly increased soil C∶N in 0~30 cm (P＜0.05). The treatment I increased N content in Cyperaceae than that of treatment VI. And also,there was a significant positive correlation between P content in Cyperacea and soil N content (P＜0.05),but there was a highly negative correlation between soil N∶P (P＜0.001). The results indicated that the treatment I could increase soil water content and SOC accumulation,it also could promote the utilization of N of plants. Otherwise,soil N content and P content jointly affected the absorption of N and P by plants through synergistic interaction.

Key words: Ecological stoichiometry, Alpine swamp wetland, Restoration techniques, Soil, Plant

摘要： 本研究利用不同生态修复技术对玉树隆宝退化高寒沼泽湿地进行修复，分析了喷灌(I)、禁牧(II)、春季禁牧(III)、喷灌+禁牧(IV)和喷灌+春季禁牧(V)对退化高寒沼泽湿地土壤及植被碳(Carbon，C)、氮(Nitrogen，N)、磷(Phosphorus，P)化学计量学的影响。结果显示：与对照(VI)相比，I,IV和V均能显著增加0~30 cm土壤含水量(P＜0.05)；I能显著增加0~30 cm土壤有机碳(Soil organic carbon,SOC)含量、C∶N和C∶P；IV对提高0~30 cm SOC含量和C∶N具有显著作用(P＜0.05)，III显著提高了0~30 cm土壤C∶N (P＜0.05)。与VI相比，I能显著提高莎草科植物N含量(P＜0.05)；莎草科植物P含量与土壤N∶P极显著负相关(P＜0.001)，与土壤N含量显著正相关(P＜0.05)。由此可见，喷灌处理对增加土壤含水量、增加SOC积累，以及促进植物对N的利用有积极作用，且土壤N和P可通过协同作用，共同影响植物对N和P的吸收。
