Abstract Based on the Landsat TM5 and TM7 images by GIS and the basic theory and method of landscape ecology,
the present agro-landscape pattern and its changes in the Sanjiang Plain during 1996~2000 are discussed in this
paper. According to an analysis of patchiness of different land use/cover types and the transition characteristics
among the main types, the cultivated land increased while the natural landscape types such as forestland,
grassland and marshland decreased considerably. The number of patches of grassland, forest and marsh increased,
but the patch area decreased, which shows a highly fragmented pattern in the study area.
