Abstract: In the late Guangxu reign (1875-1908), there were frequent adjustments to the administrative regions in Fengtian. Fengtian and Jinzhou which were the most developed regional units in Northeast China. Under the influence of various factors, such as the weakening of the status of the alternate capital, the implementation of the provincial system, local grass-roots governance, and commerce in the late Qing, two county-level administrative units were upgraded, two prefectureleveladministrative units and seven county-level administrative units were established, while one county-level administrative unit was abolished in Fengtian and Jinzhou. The mode of spatial division of the new administrative regions mainly adopted the practice of “separations within the county” and the boundaries showed a strong historical inheritance. The changes of the boundaries mainly resulted from the establishment of new counties. The alignment of mountains, rivers and the Willow Palisade were the main factors affecting the shape of the boundaries. In addition, the local twists and turns and anomalies increased the complexity of the border patterns and affected the formation of the administrative structure. Based on the experience of compiling Fengtian historical maps for The History Atlas of China during the Qing Dynasty, the article reconstructs the county boundaries of Fengtian and Jinzhou at the end Qing Dynasty.
