The invention relates to a long-time-sequence territorial space function and structure simulation method, which comprises the following steps of: firstly, carrying out territorial space function initial classification on a long-time-sequence image by adopting a random forest algorithm based on a geographic information big data platform Google Earth Engine (GEE) platform; secondly, constructing a pixel-level space-time cube, performing space-time consistency function correction, and on the basis of space-time cube segmentation and filling, utilizing an integrated forest algorithm to simulate different functional land use amount parameters of each target year in a long time sequence; and finally, deriving spatial transformation rules and spatial constraints of land with different functions according to a'double evaluation 'result, and performing simulation analysis on the land space function and structure of the target year by utilizing an adaptive cellular automaton. The method improves the recognition and simulation precision of the territorial space function and structure, is suitable for recognition and simulation of the territorial space function and structure with a long time sequence, high density and a large range, and is especially suitable for auxiliary decision making of territorial space planning and space governance.
