the weight calculation module accumulates the product of the proportion of the area of each geological condition attribute in the block range and a preset weight to calculate the weight, wherein the geological condition attributes comprise a high-incidence area, a medium-incidence area, a low-incidence area and a non-incidence area; in the weight calculation, the weight values of a medium high susceptibility region, a medium susceptibility region, a low susceptibility region and a low susceptibility region are sequentially reduced;
and the judging and triggering module is used for comparing the obtained weight calculation result with a preset triggering threshold value based on the weight calculation result, triggering the reviewing process when the weight calculation result is higher than the triggering threshold value, and otherwise, not triggering.
6. An intelligent terminal, comprising a memory and a processor, the memory having stored thereon a computer program that can be loaded by the processor and that executes the method according to any one of claims 1 to 4.
7. A computer-readable storage medium, in which a computer program is stored which can be loaded by a processor and which executes the method of any one of claims 1 to 4.
