Effects of Warming on CO2 Fluxes in an Alpine Meadow Ecosystem on the Central Qinghai–Tibetan Plateau

Abstract

Pour analyser les flux de CO2 dans des conditions de changement climatique dans une prairie alpine du plateau central Qinghai-Tibétain, nous avons simulé l'effet du réchauffement à l'aide de chambres à ciel ouvert (OTC) de 2012 à 2014. Les OTC ont augmenté la température du sol de 1,62 °C (P 0,05) et a augmenté de manière significative en 2014 (P = 0,034) dans des conditions de réchauffement. La PEG était plus sensible aux variations climatiques que l'ER, ce qui a entraîné une forte augmentation de l'absorption nette de carbone en cas de réchauffement dans la prairie alpine. En cas de réchauffement, les moyennes sur 3 ans de PEG, ER et NEE ont augmenté de 19,6 %, 15,1 % et 21,1 %, respectivement. Les modèles dynamiques saisonniers de PEG et de NEE, mais pas de RE, ont été significativement impactés par le réchauffement. La biomasse aérienne, en particulier la biomasse graminoïde, a augmenté de manière significative dans des conditions de réchauffement. L'humidité du sol, la température du sol et la biomasse aérienne ont été les principaux facteurs qui ont affecté la variation des flux de CO2 de l'écosystème. L'effet du réchauffement sur les schémas inter et intra-annuels des flux de CO2 des écosystèmes et le mécanisme des différentes sensibilités de la PEG et du RE au réchauffement nécessitent des recherches plus approfondies.

Para analizar los flujos de CO2 en condiciones de cambio climático en una pradera alpina en la meseta central de Qinghai-Tibetan, simulamos el efecto del calentamiento utilizando cámaras abiertas (OTC) de 2012 a 2014. Los OTC aumentaron la temperatura del suelo en 1,62 °C (P 0,05) y aumentó significativamente en 2014 (P = 0,034) en condiciones de calentamiento. El GEP fue más sensible a las variaciones climáticas que el ER, lo que resultó en un gran aumento en la absorción neta de carbono bajo el calentamiento en el prado alpino. Bajo el calentamiento, los promedios de 3 años de GEP, ER y NEE aumentaron en un 19.6%, 15.1% y 21.1%, respectivamente. Los patrones dinámicos estacionales de GEP y NEE, pero no de ER, se vieron significativamente afectados por el calentamiento. La biomasa superficial, en particular la biomasa graminoide, aumentó significativamente en condiciones de calentamiento. La humedad del suelo, la temperatura del suelo y la biomasa aérea fueron los principales factores que afectaron la variación de los flujos de CO2 del ecosistema. El efecto del calentamiento en los patrones inter e intraanuales de los flujos de CO2 del ecosistema y el mecanismo de las diferentes sensibilidades en GEP y ER al calentamiento, requieren más investigación.

لتحليل تدفقات ثاني أكسيد الكربون في ظل ظروف تغير المناخ في مرج جبال الألب على هضبة تشينغهاي- التبت الوسطى، قمنا بمحاكاة تأثير الاحترار باستخدام الغرف العلوية المفتوحة (OTCs) من عام 2012 إلى عام 2014. زادت OTCS درجة حرارة التربة بمقدار 1.62 درجة مئوية (P 0.05)، وزاد بشكل كبير في عام 2014 (P = 0.034) في ظل ظروف الاحترار. كانت السياسة البيئية العالمية أكثر حساسية للتغيرات المناخية مما كانت عليه السياسة البيئية، مما أدى إلى زيادة كبيرة في صافي امتصاص الكربون في ظل الاحترار في مرج جبال الألب. في ظل الاحتباس الحراري، ارتفعت متوسطات 3 سنوات لكل من السياسة البيئية العالمية، و سياسة الطاقة المتجددة، و سياسة الطاقة الجديدة بنسبة 19.6 ٪، و 15.1 ٪، و 21.1 ٪ على التوالي. تأثرت الأنماط الديناميكية الموسمية للمساواة بين الجنسين و NEE، ولكن ليس ER، بشكل كبير بالاحترار. زادت الكتلة الحيوية فوق الأرض، وخاصة الكتلة الحيوية الجرامينية بشكل كبير في ظل ظروف الاحترار. كانت رطوبة التربة ودرجة حرارة التربة والكتلة الحيوية فوق الأرض هي العوامل الرئيسية التي أثرت على تباين تدفقات ثاني أكسيد الكربون في النظام البيئي. يتطلب تأثير الاحترار على الأنماط بين وداخل السنة لتدفقات ثاني أكسيد الكربون في النظام الإيكولوجي وآلية الحساسيات المختلفة في سياسة المساواة بين الجنسين والاستجابة لحالات الطوارئ للاحترار مزيدًا من البحث.

To analyze CO2 fluxes under conditions of climate change in an alpine meadow on the central Qinghai-Tibetan Plateau, we simulated the effect of warming using open top chambers (OTCs) from 2012 to 2014. The OTCs increased soil temperature by 1.62°C (P 0.05), and increased significantly in 2014 (P = 0.034) under conditions of warming. The GEP was more sensitive to climate variations than was the ER, resulting in a large increase in net carbon uptake under warming in the alpine meadow. Under warming, the 3-year averages of GEP, ER, and NEE increased by 19.6%, 15.1%, and 21.1%, respectively. The seasonal dynamic patterns of GEP and NEE, but not ER, were significantly impacted by warming. Aboveground biomass, particularly the graminoid biomass increased significantly under conditions of warming. Soil moisture, soil temperature, and aboveground biomass were the main factors that affected the variation of the ecosystem CO2 fluxes. The effect of warming on inter- and intra-annual patterns of ecosystem CO2 fluxes and the mechanism of different sensitivities in GEP and ER to warming, require further researched.
