On the londuse background of Shanghai city, the structure properties under different grains of regional landscape are studied by using the methods of landscape ecology, and meanwhile, the variogram make it available to analyze the structure properties under different extents. The paper concludes as follows:(1)The landscape indices differ greatly with different grains. According to this research area, the research area takes on the most typical urban landscape properties with the grain of 20m.(2)The special structure of the landscape indices are basically the same with different extents, yet smaller extent are more sensitive to the change of small scale, vice versa.(3)Different landscape indices have different responses to change of grains and extents. In this paper, LSI, SHDI, SHEI are more sensitive to the change of grain, yet CONTAG and PAFRAC is less sensitive. To the change of extents, SHDI and CONTAG are more sensitive, while PAFRAC is less.(4)Different proceeds have different influence on different landscape indices, so that the special structure of different landscape indices differs a lot.(5)Generally, it shows that the patches along the directions of E0°N45°W varies more.
