Abstract：In Song Dynasty, the water system along the Yangtze River changed under the influence of natural environment and human and social factors. The changes mostly happened in watercourses and lakes. Changes of watercourses were mainly reflected in the changes of the riverbeds, shorelines, water surface and water volume along the major rivers, and the most obvious changes happened between Chenglingji and Yangzhou, where the shorelines changed frequently, and there emerged more rocky outcrops and new sandbars. Changes in lakes were mainly reflected in the changes of the depth and breadth of water of major lakes like Taihu Lake, Poyang Lake and Dongting Lake. Taihu Lake gradually shrank due to blocked water networks. Poyang Lake basically came to be what it is today. Dongting Lake kept expanding westward and sinking into its deepest point in history. Therefore, the study of the evolution of major rivers and lakes along the Yangtze River in Song Dynasty with research approaches relevant to environmental history can not only reveals changes of the river system at that time, but also provides useful experience for the development of Yangtze River Economic Circle and water protection in China.
