With rapid development of computer science, the means of the agricultural park planning are renewed continuously. Based on the long-term practice in the agricultural park planning, we put forward innovatively the integrated information processing technology in three dimensions in the paper, that is, information, time and spatial dimensions, On the basis of the coupling relation of multi-dimensional space, time and information, data information and time & spatial elements in agricultural park planning can be integrated and utilized to the maximum by 3D VR calculation as a means of basic technology application; so that a park planning system which is integrating plane, space, time and information resources is formed. By this way, the method is available for the multi-level and fully informational agricultural park planning, and it is an approach to explore modern agricultural park planning in thinking and technical means.
