Abstract

Embodiments of the invention provide a land use state prediction method, apparatus and system. The method comprises the steps of obtaining a predetermined type of image data of a target region, and generating a corresponding raster layer, wherein the raster layer at least comprises a plurality of geometric factor layers and a water body layer; according to the geometric factor layers, determining a third raster layer; training the third raster layer by utilizing a classification and regression tree to determine a development applicability probability; according to a constraint condition determined by the water body layer and the development applicability probability, building a cellular automaton model; and according to the cellular automaton model, predicting a land use state of the target region to obtain a prediction result. According to the scheme, the training is performed through the classification and regression tree to determine the development applicability probability, and the cellular automaton model is built according to the development applicability probability to predict the land use state, so that the technical problem of inaccurate prediction of the land use state in an existing method is solved.

Description

technical field [0001] This application relates to the technical field of geographic information, in particular to a method, device and system for predicting land use status. Background technique [0002] In land planning, in order to use land better and more effectively, it is often necessary to predict the future state of land use in the target area, and then carry out specific land use planning based on the prediction results. [0003] The existing prediction methods of land use status usually construct cellular automata models to simulate the specific process of urban land use evolution, and then predict the land use status. Specifically, for example, it is possible to predict whether a piece of land will become urban land in a few years. Or, the probability that a piece of land will become urban land in a few years. Wherein, the cellular automaton may specifically be a grid dynamics model in which state and space-time are all dispersed. [0004] In practice, the exis...
