Regional environment monitoring method and device based on space-time remote sensing

The invention discloses a regional environment monitoring method and device based on space-time remote sensing, which are used for improving the accuracy of environment monitoring based on space-time remote sensing. The scheme provided by the invention comprises the following steps: acquiring a data set of a to-be-monitored area, wherein the data set comprises a plurality of space-time remote sensing data values acquired from the to-be-monitored area and at least one missing value; prediction interpolation vectors corresponding to multiple window ranges are determined for the target missing value based on a preset interpolation algorithm, and the multiple window ranges are window ranges of multiple sizes determined with the missing position of the target missing value in the data set as the center; the prediction interpolation vector comprises a prediction interpolation value corresponding to each time-space remote sensing data value in the corresponding window range; based on the space-time remote sensing da
