　　为了揭示肇源县土地利用景观格局的发展变化，合理利用土地，通过选取1992、2001、2010年的TM遥感影像，通过采用景观生态学原理和GIS技术，选取景观构成、平均斑块面积、斑块密度、景观蔓延度、Shannon多样性指数和均匀度指数等进行分析，研究肇源县近20年的景观格局的发展规律。结果表明，耕地、盐碱地景观面积增加，草地、水域和湿地景观退化较严重，景观连接性增强，破碎度降低，景观格局复杂性降低，景观格局受人类活动影响加剧。

In order to reveal the landscape pattern evolvement of land use and for rational utilization of land in Zhaoyuan County, the paper used the Landsat TM images in 1992, 2001 and 2010, by using the theory of landscape ecology and the technology of GIS. The landscape pattern development of Zhaoyuan County in the past two decades were explored by many indices. The indices chosen were the structure of landscape, the average area of patches, patch density, landscape contagion, Shannon landscape diversity and evenness index. The results showed that, the area of cultivated land and saline land increased, while grassland, waters and wetland degrade more seriously. The landscape connectivity enhancement, the landscape fragmentation reduced and the complexity of landscape pattern reduced. The results also showed that, the landscape pattern due to the influence of human activities aggravated in Zhaoyuan County.
