摘　　要：应用不同时期的航空遥感图像，编制各期景观单元图，在ＡＲＣ／ＩＮＦＯ系统的支持下，建立空间信息库，选取斑块大小、分维数、优势度、多样性指数、破碎度等指标，对杨陵农科城景观空间格局的动态变迁进行了分析。结果显示，从１９６８～１９９５年，杨陵正在由一个乡村小镇演变成一个农业科学城，城市化指数逐步增大，景观空间格局发生了较大的变化。Using the aerial remote sensing pictures taken in different periods different landscape unit charts were drown up and under the support of the GIS the space databask was establish. Patch size, fractal dimension,dominance,diversity index,evenness index,fragmentation were use to analyze the spatial landscape patten developments of Yangling.The results showed that Yangling is becoming an agricultural science city.The urbanization indexes are growing annually and the spatial landscape pattern has changed complicately.
