Abstract: Based on comprehensive geological survey in Laizhou Bay, we calculate the weights of evaluation factors with the method of analytic hierarchy process and fuzzy comprehensive evaluation. The results indicate that hundreds of evaluation units were divided within the research area. With the use of fuzzy comprehensive evaluation formula integrated with computer program and the spatial analysis function of MAPGIS, we evaluate the crust stability, surface stability and foundation stability following the evaluation standard of geological environmental stability in the study area. We evaluate the engineering geological environment quality and establish the subareas with integration of all evaluation factors in the whole study area.
