Abstract：Aerospace-borne and ground based integrated earth observation sensor web can achieve dynamic management of multi-sensor， intelligent sense of events，multi-platform systems coupling，on-demand observation ，observation integration，data assimilation and intelligence services under the network environment. It can effectively solve the problem that current sensor data can not be coordinated observated， lack of data processing and information extraction capacity， and the lack of aggregation service model and other issues. It is the first important issues that need to be solved by smart earth and integration of earth observation system， and it is one of the leading subject of Earth's land surface monitoring and decision-making. The project focused on a study of three scientific questions： the event perception and coordination of multi-sensor observation mechanism ， data assimilation and information processing theory of earth observation sensor networks， and task-driven collaborative spatial and temporal information service model：（1） From the angle of systems theory， cybernetics， ontology and service，it research on the adaptive dynamic coupling mechanism and optimization of earth observation model ， in orbit of Earth observation data processing methods ， observing resource network theory.（2） Using the theories and methods of system science ， it will establish temporal - spacial -spectral integrated data fusion methods， and develop Earth observation data and sensor networks land surface model of multi-parameter joint assimilation methods，study multi-sensor networks intelligent processing and analysis of source data models of the Earth observation.（3） From the system architecture of earth observation sensor network， it will use the ontology， operations research， cybernetics and related methods to conduct research on task-oriented behavior planning model. With multidisciplinary joint research， it will systematically reveal the transformation mechanism of events perception to service， establish the scientific theory and methodology of achieving monitoring land surface from the temporal - spacial -spectral sensor networks data， lay a foundation of earth observation theory and technical basis for temporal - spacial -spectral collaborative systems in our country.
