摘　　要：采用遥感和地理信息技术,对大理至丽江高速公路建设前沿线景观和建设后沿线模拟景观进行分类和制图,并进行高速公路修建前后景观指数计算,从类斑和景观2个层次上分析了高速公路修建前后景观格局的变化.结果表明:高速公路的建设将导致景观格局的改变,缀块数目、缀块密度增加和最大缀块指数的减小,表明景观异质性增加;通过公路两侧缓冲区取样分析,高速公路修建对沿线小范围的景观格局影响较大,随着离公路距离的增加,影响逐渐减小.Using the remote sensing and geographical information technology,the landscape of the Dali-Lijiang highway were classified and charted and changes in the landscape before and after the highway construction were analyzed.The result showed: the landscape pattern will change after the highway construction.Patch number,Patch density increased and Largest patch index decreased showing the landscape heterogeneity increased.From the analysis of different buffers we can get:the impact of highway construction on the...
