摘要： 为了探讨松原市近20年间，在三北防护林建设背景下的土地利用景观格局变化，为吉林省西部新开水田区防护林建设提供参考，以1989年和2010年2期松原市的Landsat TM影像为数据基础，通过景观格局的特征、动态变化、转移矩阵和景观格局动态变化，定量分析松原市景观格局的动态变化。结果表明：松原市近20年间优势景观为耕地、盐碱地和草地，三者占研究区土地总面积的85%以上，其他景观类型呈补丁状分布在研究区内；土地利用类型变化经历了急剧到缓慢的过程；土地利用类型转移主要表现为大量草地和盐碱地向耕地景观类型的转化。景观密度，形状指数和最大斑块指数增加，表明防护林建设对研究区控制作用增强，景观破碎化加剧，形状愈加复杂；景观多样性和均匀度均减小，多样性降低，异质性减弱，蔓延度增大，连通度增加。

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.
