【Abstract】 Biogeochemical modeling plays a role as important as experimental measurement in ecosystem research. This paper analyzed the development of biogeochemical model using TEM and DNDC model as cases. Current biogeochemical models were classified according to modeling method, application purpose,element concerned, ecosystem type,and spatial scale. The basic framework (three component:plant,air and soil,and three interface:plant air,plant soil,and soil air) and interior fundamental processes (physical,chemical and biological processes) of biogeochemical models were reviewed,and some important problems concerning biogeochemical modeling,such as scale upping,integrating GIS and remote sensing,involved human activity,and comparison study were focused.更多还原
