中文摘要
Terrestrial ecosystems on the Asian continent have been accumulating carbon during the past century in response to longer growing seasons and CO2 fertilization. The processes controlling the long-term dynamics of carbon sequestration must be fully understood to enable spatial temporal projections under various climate and land cover change scenarios. Here, we propose to work with dynamic global vegetation models to evaluate the sensitivity of vegetation dynamics to changes in climate and disturbance (via fire) and propagated effects to the carbon cycle. We will evaluate and modify model structure and parameters by combining field plot and remote sensing data on greenness and burned area trends. Reducing the uncertainty of carbon cycle processes depends on a more thorough investigation and realistic representation of vegetation dynamics and disturbance. We expect to publish two manuscripts from this research and present the findings at an international conference (American Geophysical Union).
