Abstract

The invention discloses a tensor-based land utilization simulation method, system and device and a storage medium. The method comprises the steps of obtaining land utilization data, driving factor data, a conversion cost table and an inertia intensity table; training a convolutional neural network to obtain a fitting model, and further obtaining a conversion probability tensor; executing neighborhood influence calculation to obtain a neighborhood influence tensor; executing conversion cost calculation to obtain a conversion cost tensor; executing inertia coefficient calculation to obtain an inertia coefficient tensor; obtaining a combined probability tensor according to the conversion probability tensor, the neighborhood influence tensor, the conversion cost tensor and the inertia coefficient tensor; and executing tensor wheel disc selection on the combined probability tensor to obtain a simulation result. According to the method, each part in the land utilization simulation process based on the cellular automaton is formalized into the tensor, and the tensor framework is applied to accelerate the operation, so that the efficient land utilization simulation process is realized while the complex parallel algorithm design and CUDA programming are avoided.
