The invention relates to the technical field of territorial
resource planning, in particular to a territorial space
resource planning system based on
big data, which comprises a space-time diagram modeling module for summarizing
land utilization data, extracting a
land utilization type of each geographic unit, embedding type data into space-time diagram nodes, and calculating a space-
time dependency relationship among the nodes; and generating a space-time diagram
adjacency matrix. According to the method, space-
time dependency between nodes is modeled through space-time diagram
processing, complexity of space and
time changes is accurately captured, and the
system can effectively recognize short-term and long-term change features by combining differentiated
time windows and small and large window
convolution kernels, so that prediction of
land utilization changes is more flexible, and the prediction accuracy is improved. The spatial
adjacency matrix is further adjusted through multi-scale
spatial heterogeneity modeling, the mutual relation between the areas is accurately described, the precision of
spatial dependency calculation is improved, data trends of different time steps are subjected to weighted fusion, land utilization changes are effectively predicted, and more accurate reference is provided for
decision making.
