Abstract: In order to improve efficiency and accuracy of decision-making of capital agricultural, according to current situation and features of the agriculture in Beijing, integrating global positioning system (GPS）and remote sensing (RS) as tools of data capture, and the internet platform as a passage of transmission and share of the data, using a set of new technologies, e.g. business flow, spatial and temporal analysis, and middleware, an efficient system of information technology services was built, which have the functions of collecting, dealing, transmitting, storing, analyzing, and applying of the data. The integrative innovation broke through such problems as a fusion of multi-source heterogeneous data, on-line incremental update, and decision-making methods for agricultural management, and established management and decision support system of capital agricultural based on GIS. This paper selected facilities agriculture facilities and animal diseases for technical application object, and achieved decision support about planning and structural adjustment of agriculture facilities and online editorial management functions, while achieving decision support about prevention and control of animal disease emergency. Running of the system proves a promotive transition from the traditional, rough and experimental mode towards to the precise, synergetic, and scientific mode and provides sufficient basis for agricultural management to make rapid and scientific decision.
