Abstract: Based on 3S techniques, the study compared the landscape structures of orchard and no-irrigable cropland of 16 typical basins in Yantai City by using the land-use-map of Yantai City and the Landsat TM image in Sept. 9, 2002. The percentage of landscape, patch density, perimeter-area fractal dimension and patch cohesion index were calculated by using Fragstats 3.3. The results show that though Yantai City is famous for its vegetables and fruits, the proportion of orchard is not the largest in area. Non-irrigable cropland landscapes are dominant in area and orchard landscapes are dominant in patch number. The conclusion made through comparing different landscape indices is that the average percentage of non-irrigable cropland landscape is higher than that of orchard landscape. The average, the largest and the smallest patch densities of orchard landscape are higher than those of non-irrigable cropland landscape obviously. No significant difference between orchard landscape and nonirrigable cropland landscape in perimeter-area fractal dimension is observed, but there are great changes from orchard landscape to non-irrigable cropland landscape in patch cohesion index.
