| 中文摘要 | Natural wetland vegetations are sensitive to climate change, and net primary productivity (NPP) of dominant plants is one of the important indexes to understand the feedback mechanisms to these global or regional change events. In this study, we attempted to utilize BIOME-BGC model to simulate NPP of Calamagrostis angustifolia in Fujin, in Sanjiang Plain of China. The Calamagrostis angustifolia is the dominant plant community (34.5%) in Sanjiang Plain, a typical wetland region. Field-based physiological data of Calamagrostis angustifolia and collected information are used to optimize the parameter of BIOME-BGC by a progressive optimization method. Our results showed that the optimization method significantly improved the simulation of wetland vegetation. In the correlation analysis between the simulated and measured values, the R-2 value increased from 0.68 to 0.87, while the standard error decreased from 449.8 g C m(-2) a(-1) to 164.0 g C m(-2) a(-1). The long-term temporal variations showed that NPP of Calamagrostis angustifolia slightly increased from 1963 to 2012. In addition, we found that precipitation was the dominant factor affecting NPP, with a significantly positive relationship (R2=0.59, P<0.05). These kinds of relationships indicate that the variation trend of the future climate might increase NPP of Calamagrostis angustifolia in the study region. |
