The key plan that spurred this process of linking the old city with the West Lake was a plan titled "Building a New Market"(1914). By elucidating the time, process, and contents of the plan, this paper analyzes the spatial transformation of the lakefront districts based on old maps, and then interprets how it led the forming process of the "city-lake integrated" urban form in Hangzhou.展开更多
