青藏高原高寒草甸生态系统碳通量特征及其控制因子
Carbon Flux and Controlling Process of Alpine Meadow on Qinghai-Tibetan Plateau
【摘要】 青藏高原特殊的气候变化特征,在区域生态系统碳动态平衡起着重要作用。本文就青藏高原不同生态系统CO2通量的时空变化及其影响因子和控制途径进行综述,以明确青藏高原植草地生态系统的碳源汇状况及时空变化特征,为全球变化的研究提供依据。
【Abstract】 The Qinghai-Tibetan plateau possesses the largest area of natural grasslands in China.The grassland ecosystem on the plateau is hypothesized to play an important role in the carbon balance in both regional and global ecosystems.It is therefore of great significance to study the carbon flux of alpine meadow vegetation.The paper mainly summarizes research advances about the characters of carbon source/sink and carbon spatio-temporal variation for alpine meadow ecosystem on Qinghai-Tibetan plateau as well as conducts some analysis of related researches in the future.
