   通过对青藏高原主要植被类型碳收支研究发现,矮嵩草草甸和金露梅灌丛草甸具有较高的CO2吸收潜能,而沼泽化草甸具有较低的排放潜能,其差异主要是由于植物光合能力不同和土壤呼吸差异引起的;温度也是影响青藏高原碳收支的一个重要因素。模拟温度升高可导致青藏高原高寒草甸生态系统生物多样性急剧下降,土壤等环境发生剧烈变化,暗示了高原在未来全球变化背景下生态安全的危险性。同时发现高寒草甸植物对地球甲烷的释放作用研究报道,发现高寒草甸草本植物群落具有排放甲烷的能力,而木本灌木群落具有氧化大气甲烷的能力。我省进行碳贸易与生态补偿、草地生态系统的可持续发展和生态系统管理提供坚实的理论基础与技术支撑。首次在青藏高原极端环境下发现土壤微生物中放线菌类的一个新属。
