Optimization of urban morphology for comprehensive disaster prevention supported by GIS

摘要

In the rapid urbanization process, there are many irrational existences of urban morphology, thus a large amount of potential disasters lurk. The paper aims to throw a light upon the present urban morphology and some conflicts about urban disaster prevention. This research was given from the viewpoint of urban disaster prevention through several cases of different types of urban disaster. Then the relations between the optimization of urban morphology and urban disaster prevention were analyzed, e.g. location of the city, urban size and environmental capacity, direction for urban development, space urban structure, etc. Furthermore, an application was probed, which was used by some space information technology, such as GIS, in the disaster-oriented urban form optimization.
