Abstract: Wenchuan Earthquake with floods played a huge role in the destruction to arable land of catastrophe areas. In this paper, from the point of view of the recovery and reconstruction of agricultural production after the earthquake disaster, based on the integrated view of disaster system, an Arable Land Hazard Degree Index Model was established, which took township of Jiangyou City as the basic statistical unit. Ten indicators, such as disaster situation, pregnant disaster environment and the rebuilding pressure of arable land of the bearing disaster body, were selected, and R-type factor analysis method was used. Then supported by ArcGIS, Jiangyou City was divided into different hazard degree zones of arable land. The results showed that, among the 40 towns in Jiangyou City, there are 18 towns, accounting 45.31% of city land were severely damaged, mainly distributed in the central city western mountainous and hilly transition zone and the hilly areas, in which 7.76% disaster area could not carry on land reclamation; while there were 10 towns, accounting 22.17% of city land were moderately damaged, mainly locating in the northwestern mountains, as well as the transition zone between the mildly and severely damaged arable land area, in which 4.39% disaster area could not carry on land reclamation; and there were 12 towns accounting 32.52% of city land were mildly damaged, mainly spreading in the eastern plains and the transition zone of plains and hills, in which 0.76% disaster area could not carry on land reclamation. The results can be used to guide the cultivated land reclamation and provide scientific basis for agricultural ecosystems restoration.
