Abstract:: This article takes Longquanyi district, Sichuan, as an example and then studies the changes of landscape structure and the driving factors by the technique of GIS and the method of landscape-ecology.We use the landscape acreage index, landscape fragmentation index, landscape apartness index, landscape diversity index, landscape dominance index, landscape evenness index and landscape shape index, to analyze the characteristics of the changes of landscape based on the landscape structure in 1996 and 2004.The landscape structure has intensively changed; the diversities of acreage ratio of various landscapes and the extent of landscape fragmentation have augmented a lot, the structures of land utilization get more complex, the extent of abnormity of landscape shape has enhanced.The villages and towns in Longquanyi have different landscape structures, due to the different physical, economic, and social conditions.And what’s more, when analyze the driving powers of landscape structure, it is found that the increase of population and development of third industry are the leading driving factor; industrialization, the planting of fruit, and the tourism in rural areas are another driving power.
