Application and development of terrestrial biogeochemical model

Abstract

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 GISand remote sensing,involved human activity,and comparison study were focused.
