Regional grain safety guarantee capability quantitative evaluation method based on space matching degree

The invention provides a regional grain safety guarantee capability quantitative evaluation method based on a space matching degree. The method comprises the following steps: collecting and concluding grain safety basic data information of multiple departments; performing set processing on the grain security data, performing processing work such as format recognition, image recognition and classification extraction on multi-source and multi-format data, and establishing a grain security data resource pool; and designing a spatial data generator, extracting data from the grain security data resource pool for spatialization processing, constructing a spatial database, and performing attribute information hitching on the spatial data. Meanwhile, an index evaluation system is constructed and calculation is carried out, and consideration is carried out from multiple dimensions of population, storage, processing, emergency and transportation in the aspect of a space aggregation degree index aiming at guarantee popu
