主　　题：temporal geographic information system environment dynamic model 

摘      要：Temporal geographic information system(t_GIS) is a kind of computer information system that can display,process and analyze the micro_format distribution of temporal_spatial information of real *** includes both spatial geographic information and temporal information,and can analyze both the static geographic information and the dynamic geographic information. Three models based on t_GIS for environment dynamics,namely,the mechanism method,the experience method and the mixed method are given. t_GIS based on the environment dynamic model has more new functions than traditional GIS,such as fast I/O,inquiry,static/dynamic display and visible analysis of spatial and temporal sequence information,especially it can display the image of the evolution in the past,current and future environment through the extrapolation method within its defining *** velocity for analogue display can be accelerated by setting up time_varying_area_function for position and attribute. Dynamic environmental information analysis systems based on t_GIS are applicable to almost all the fields related to management,display and analysis of local environmental dynamic *** this reason,some considerations to construct distinct information systems have been enumerated in this paper,such as,the analysis information system for terrain evolution,the analysis information system for the condition of water and fertilizer of farmland,analysis and the evaluation information system for ecological environment,and the analysis information system for distribution changes of population of China,etc.
