This article calculated the spatial characteristics and matching degree of gravity center shift between urbanization and ecological environment by variable weight theory and the evaluation method of gravity center model. The results show that: (1) the gravity center of urbanization and ecological environment in Jilin Province shows certain phase fluctuation in longitude, latitude, northeast, southeast, northwest and southwest directions; (2) the distribution of the gravity center of ecological environment is relatively concentrated, while the spatial distribution of the gravity center of urbanization is relatively loose, and the fluctuation of its displacement is relatively stable; (3) The direction of center displacement of urbanization is northeast, and the direction of gravity center displacement of ecological environment is southwest.
