Assessment of Geological Environment Bearing Capacity of Fengjie New Town Based on AHP

摘要

Because of the problems, such as bad geological conditions, great difficulty of construction, and high investment cost, Fengjie new Town has changed the location three times in reservoir resettlement project. Considering the geological and regional feature, this paper first constructs the assessment index system of geological environment bearing capacity; and then obtains the weights of assessment indexes based on AHP; finally through extracting, analyzing and processing the of assessment indexes by means of GIS, gets the zone map of geological environment bearing capacity of Fengjie County Town. The results not only provide an evidence for the construction plan for Fengjie new Town, but also provide a reference for relocated cities of similar reservoir areas and city construction of hilly and mountainous areas.
