Abstract:Regional economic construction and social development must adapt to geological environment guarantee ability. The evaluation of geological environment guarantee ability is a spatial comprehensive evaluation involving multi-level and multi factor action. In the process of evaluating geological environment support capacity of Shandong Peninsula Blue Economic Zone, two domain layers, 11 criterion layers and 37 index layers are selected to establish the evaluation system, the weight of each evaluation index is determined by analytic hierarchy process, and spatial processing and superposition operation of graphics are carried out based on GIS. According to the determined classification standard, geological environment guarantee ability is divided into five levels, they are strong, rather strong, medium, rather weak and weak.
