以四平市为研究区，利用1976-2014年Landsat系列影像，基于GIS技术，运用景观生态学原理，分析四平市景观格局演变特征，并对城市未来发展变化进行情景预测.结果表明，近38年，四平市耕地面积因被建成区占用而减少；而建筑用地呈快速增加趋势，年均增长2.67%.耕地、林地、草地和未利用地的景观分离度呈增加趋势，景观破碎化加剧；而建筑用地分布趋于集中.城市景观多样性指数增加，城市将继续扩展.根据预测，未来6年耕地面积仍呈减少趋势，建筑用地面积快速增长，建成区沿NW-SE轴向扩展.

Taking Siping city as the study area,using landsat series images during 1976 to 2014,and based on the principle of landscape ecology,then the characteristics of landscape pattern and future urban development can be acquired. The results showed that the Siping farmland reduced because of occuping by building land. The building land showed a trend of increased rapidly which average annual growth by 2. 67% nearly 38 years. The land landscape isolation of cultivated land,forest land,grassland and unused land increased. The index of landscape fragmentation increased while the building land’s distributions centralized. The urban landscape diversity index increased which means that the city will continue to expand. According to the forecast,the area of farmland and building land area would growth rapidly and buiding land areas would extended by the direction of NW-SE.
