A FRACTAL STUDY ON URBAN SYSTEM IN NORTHEAST CHINA

The paper made a preliminary study on the spatial structure of urbansystems which take Shenyang, Changchun and Harbin as centers respectively innortheast China. A law is found that the spatial stracture becomes gradually loosewhile the level of aggregation' tends to rise from the south to the north based on themeasurement and calculation of fractal dimension and fractal structure factor. Theauthor discussed how the spatial patterns formed and lastly put forward suggestionsto improve the supervision of the urban systems in northeast China.
