摘要/Abstract

摘要： 研究青藏高原东部窄叶鲜卑花高寒灌丛生长季根际和非根际土壤多酚氧化酶和过氧化氢酶活性对增温(1.3 ℃)的响应,分析全球气候变暖对高寒灌丛根际土壤生态过程的影响.结果表明:生长季中期根际和非根际土壤多酚氧化酶活性显著高于生长季初期和末期;而土壤过氧化氢酶活性在非根际土壤中随生长季节逐步提高,在根际土壤中没有表现出明显的季节变化.在非根际土壤中,增温使生长季末期土壤多酚氧化酶活性和生长季中期土壤过氧化氢酶活性显著提高17.5%和2.2%,而在其他时期对2种土壤酶活性没有显著影响.而在根际土壤中,增温仅在生长季初期使土壤多酚氧化酶和过氧化氢酶活性显著提高6.5%和1.3%.在整个生长季,土壤多酚氧化酶活性均表现为正根际效应,土壤过氧化氢酶活性的根际效应不明显,而增温仅在生长季末期使土壤多酚氧化酶活性的根际效应显著降低15.2%.这表明,未来气候变暖背景下青藏高原东部高寒灌丛生态系统根际与非根际土壤多酚氧化酶和过氧化氢酶活性将发生不同的变化,进而影响高寒灌丛根际土壤生态过程.

Abstract: To understand the effects of climate warming on rhizosphere ecological processes in the alpine scrub ecosystem, the responses of polyphenoloxidase and catalase activities in the rhizosphere and bulk soils to experimental warming (1.3 ℃) were examined during the growing season in a Sibiraea angustata scrub ecosystem on the eastern Qinghai-Tibetan Plateau, China. The results showed that the activities of polyphenoloxidase in rhizosphere and bulk soils in the middle growing season were significantly higher than those in the early or late growing season. The activities of catalase in the bulk soil increased gradually during the growing season, while they showed no seasonal changes in the rhizosphere soil. In the bulk soil, warming significantly increased the activity of polyphenoloxidase by 17.5% in the late growing season and increased that of catalase by 2.2% in the middle growing season, whereas it did not affect soil enzyme activities in early or late growing seasons. In the rhizosphere soil, warming only significantly increased the activities of polyphenoloxidase and catalase by 6.5% and 1.3% in the early growing season. The rhizosphere effect of soil polyphenoloxidase activity was positive throughout the growing season, while there was no obvious rhizosphere effect for soil catalase activity. Furthermore, warming significantly decreased the rhizosphere effect of soil polyphenoloxidase activity by 15.2% during the late growing season. These results indicated that the activities of polyphenoloxidase and catalase activities differed between rhizosphere and bulk soils, with consequences on the rhizosphere soil ecological processes under climate warming in the alpine scrub ecosystem on the eastern Qinghai-Tibetan Plateau.
