With the rapid improvement of the urbanization process in Shenyang, the urban construction land expands greatly, which makes the urban morphological characteristics change rapidly. In order to guide the city to develop in a more reasonable, healthy, and orderly direction, this article analyses the evolution of urban morphology in Shenyang. By selecting three different periods of satellite remote sensing images in 2001, 2006 and 2014. With the help of Remote Sensing manual interpretation method, the construction land data of the three years in the city are extracted. According to the fractal theory, the laws of urban development morphology are analysed, and the characteristics of urban morphological evolution are summarized. Results show that: 1) the area of urban built-up areas increased by 3.7 times from 2001 to 2014, with an average annual growth rate of 21%. The expansion direction is southwest and northeast. The main reason lies in the development and construction of the southwest side of the Yuhong District and the Shenbei New District.; 2) By analysing the quantitative indexes such as expansion intensity index, compactness index, boundary dimension index and shape index, it is found that the urban expansion of Shenyang is characterized by stages, and the expansion speed in 2006-2014 is significantly lower than that in 2001-2006. This phenomenon indicates that the internal structure of the city has stabilized and it has begun to focus on intensive development; 3) Shenyang has gradually formed a "one-axis, onebelt" urban spatial pattern, focusing on the coordinated and unified development of multiple centres.
