摘要

This paper will take Heilongjiang Province as an example, give cross-bred  quantitative evaluation for the county by comprehensive risk index method of geological disasters. First do mesh dissection on the county administrative zoning map,  then according to the geology, topography (slope), climate (vegetation coverage) and human engineering activities conditions of each unit, using the space analysis function of MAPGIS, to get its potential geological disasters intensity index and current geological disasters intensity index. By assigning numbers to each and add up them, the authors could obtain the comprehensive geological hazards risk index of the units.
