Recently,a new multidisciplinary scientific study,called earth system dynamics,is developing on the basis of considering the atmosphere,oceanosphere,geographic environment and biosphere in the Earth and their linkages together as a whole system.By so doing,the scientific community is able to combine the global climate change studies(such as WCRP and IPCC)and the so-called global change studies(such as IGBP)and some other important scientific plans in the world(such as IHDP and DIVERSITAS)as unified scientific problems to understand more correctly and all-roundly the laws governing the changes in the climatic,environmental and ecological systems,and to provide more reliable prediction of their changes in the future.One of the major tasks in the earth system dynamics is to set up an earth system dynamic model with sound theories because a reliable prediction for climatic and environment-ecological change can be made only by the use of such model.This paper summarizes some related researches and achievements of the earth system dynamic model in recent years in China,especially those just before and during the implementation of the science plan in the Chinese Academy of Sciences(CAS)named "Study on the Earth System Dynamic Model",in which some results are found to be unique and new although the studies are preliminary.The main tasks and some important scientific problems for development of the earth system dynamic model in China are also pointed out.The paper is arranged by the main sub-systems of the earth system,except for the introduction and summary.They are the atmospheric general circulation model(AGCM),the physical-hydrological process model in the earth surface layer(LSM),the oceanic general circulation model(OGCM)and the oceanic biogeochemical model,the aerosol and atmospheric chemistry model,the dynamic global vegetation model(DGVM)and some related ecological problems,the biogeochemical model and some related studies of the ground-based stations for surface physical and biogeochemical observations in the arid and semi-arid regions,and some specific studies of land-atmosphere interactions in the arid and semi-arid regions and their influences both insitu and on monsoon.
