【 摘 要 】

This paper, on the basis of results achieved recent years related to interaction mechanism of landscape pattern and ecological process from the study area, mainly studies evolution characteristics of the landscape pattern in Lushan County, Soustwest China after earthquake with the support of landscape ecology method and the GIS technology. Through data-analysis at three phases, it is concluded that there exists a positive correlation between the land use change of the earthquake-stricken areas and the intensity of human disturbance and between the change of landscape pattern index and the intensity of human disturbance; that there is, in the landscape pattern of the earthquake-hit areas, a trend of good landscape "encircling" and "dispersing" bad landscape under the influence of human disturbance; and that human disturbance exerts positive effects on the ecological restoration from 2008 to 2012 and from 2013 to 2017, but negative effects from 2012 to 2013.
