SIMULATION OF THE NET PRIMARY PRODUCTIVITY OF THE WETLAND PLANTn Calamagrostis angustifolia BASED ON BIOME-BGC MODEL

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 physi
