Aiming at a current layout-type environmental risk and regional environment risk analysis situation, the invention provides a method for regionalizing regional abrupt environment risks based on a GIS technology. The method comprises the following three steps: firstly, based on a regional abrupt environment risk system analysis, constructing an environment risk regionalization index system; then, constructing a series of point, line and surface concept model so as to realize regionalization index quantification, carrying out a cluster analysis to similarity of an index attribute character, carrying out practical adjustment to cluster graph spot fragments according to a regional macroscopic planning so as to realize the bottom-up regionalization of the regional abrupt environment risks and acquire a subregion of the regional abrupt environment risks; taking a space-time pattern of the regional abrupt environment pollution accident risks as a basis of the top-down regionalization so as to acquire a large region
