This study aims to evaluate the ecological restoration of Wenchuan County after the Wenchuan Earthquake in 2008

and to provide support for further ecological restoration and reconstruction. Simultaneously

this study also focuses on applying remote sensing and Geographic Information System（ GIS） technologies to evaluate the ecological environment. Wenchuan County

which was the epicenter of the May 12

2008 earthquake

was selected for this research

which involved multi-source r emote sensing data and other supporting statistical data. An eco-environmental quality evaluation index system was established based on the pressurestate-response framework. The analytic hierarchy process method was used to calculate index weight. The eco-environmental qualities of Wenchuan County in 2007

2008

and 2013 were evaluated by using the comprehensive index method. The results for the eco-environmental quality evaluation of Wenchuan County in 2007

2008

and 2013 were obtained. Data gathered on the eco-environmental quality of Wenchuan in 2008 were compared with those obtained in 2007

i. e.

before the earthquake. Data on the e co-environmental quality recovery gathered in 2013 were also compared with the data in 2007（ i. e.

before the earthquake） and2008（ i. e.

after the earthquake）. The result of the analysis showed that 79. 4% of Wenchuan County exhibited good eco-environmental quality in 2007. However

the eco-environmental quality of the county was severely damaged by the 2008 earthquake. In particular

the areas near the epicenter suffered from serious destruction. Five years after the earthquake（ 2013）

the e co-environmental quality of Wenchuan County has been successfully restored. In particular

55. 84% of the regional eco-environmental quality of the county has significantly improved compared with that in 2008. The eco-environmental quality of poor regions in the county has also exhibited an obvious improvement. However

the eco-environmental quality in some regions in the county has not fully recovered. Evaluating and analyzing the eco-environmental quality of Wenchuan County in 2007

2008

and 2013 are feasible by using remote sensing and GIS technologies. Such approaches help determine the space distribution of the eco-environmental quality of Wenchuan Earthquake and evaluate its recovery. This study offers several useful recommendations on protecting and restoring the ecological environment that can be applied in the future.
