Abstract: The geological environment is a prerequisite for regional development. There are such geological environmental problems as landslides,goaf collapse, ground subsidence, and seawater intrusion etc. Regional development cannot break the bearing capacity of geological environment. The bearing capacity is a dynamic changing process.It is necessary to take into consideration both the basic conditions of the geological environment and the bearing status.Through the analysis of regional geological environment characteristics, this paper builds an evaluation index system of bearing capacity of geological environment on the basis of the "bearing foundation-bearing status-bearing potential" model. A comprehensive evaluation were finally obtained by using AHP and arcgis10 spatial analysis functions. The results show that:the carrying capacity is quite weak near the areas of the Yishu fault zone, the Laizhou Bay, the Jiaozhou Bay, and the Yellow River Delta; in the western part of Shandong and the northern Yantai, the bearing status is overloaded due to human activities such as mining and groundwater over-exploitation.The northwest, southwest and most parts of Jiaodong Peninsula have a large capacity of bearing potential.Some relevant countermeasures and suggestions are proposed in the end.
