摘要
Geomorphological classification of the Fujian province was done based on remote-sensing imaging, digital elevation maps, and slope gradient data acquired by ArcGIS 9.2. The engineering geological units in the Fujian province were divided into five types by the geomorphologic shape and genesis. The relationship among geomorphological type, engineering geological unit, and site category was determined using engineering geological data and site category data. Then, after making a preliminary site classification adjusted by drill hole data, the site was classified into four types： Ⅰ0, Ⅰ1, Ⅱ, and Ⅲaccording to site classification standards of equivalent shear-wave velocity and overburden thickness. The results showed that the site categories in the Fujian province mainly consist of type Ⅱ, which accounts for 85.26 % of the land area. The percentage of Io was the smallest, which accounts for only 2.44 % of the total area.
