| Abstract: | Based on questionnaire surveys on farmers and historical information analysis,this article takes three administrative villages of typical townships of Dujiangyan City as its research objects,and studies pattern variations and farmers’ livelihood features in residential areas of the three administrative villages in 2007(before the earthquake) and in 2010(after the earthquake) by means of GIS technology,scene analysis,mathematical statistics,and so on.The results show that:① the spatial patterns in typical rural residential areas in earthquake-stricken region before and after the earthquake disaster have changed greatly due to the influences of multiple factors;② generally speaking,the typical rural residential areas are in a process of changing from dispersed distribution to concentrated distribution under planning and guidance;③ the variations in residential areas have caused the corresponding changes in farmers’ selection of means of livelihood. |
