The Evaluation of Geological Environmental Quality and the Partition in Wuhan Megalopolis

In this paper, the author taking the geological problem of environment and occurred geological disasters evaluating objects, apply GIS HAP to evaluate three subsystems of rock environment, environmental soil, water environment which affect the quality of geological environment of Wuhan megalopolis. By analyzing the main factors which affect the subsystems, the author establishes subsystem hierarchy structure model and quality mathematic exponent model in order to reach the quality exponent of each subsystem which could be utilized quality of each subsystem, based on this, the author carries out a systematic evaluation of geological environment of Wuhan megalopolis.
