Abstract: To explore the dynamic variation of landscape pattern of land use in Songyuan City in nearly 20 years, under the Three-North Shelterbelt construction background, and provide reference for the shelter forest construction of paddy field reclaimed in recent years in the west of Jinlin Province, the author chose Landsat TM images in 1989 and 2010 of Songyuan as the main datasource, and quantitatively analyzed the dynamic change of landscape pattern by landscape pattern characteristics, dynamic changes, transfermatrix and landscape dynamics in Songyuan. The results showed that: the dominant landscape in the past 20 years in Songyuan City was arable land, saline-alkali soil and grass, the three accounted for more than 85% of the total land area of the study area, the other landscape was a patch-like distribution in the study area; land use changes from sharp mainly to the slow process; transfer of land-use types for a lot of grass and saline conversion to arable landscape types. Landscape density, shape index and plaque index increased, indicated that the shelterbelt construction enhanced role of the study area control, landscape fragmentation intensified, increasingly complex shape; landscape diversity and evenness decreased to reduce diversity, heterogeneity weakened spread increases, increased connectivity.
