Abstract: The lakeside area is an essential ecological and landscape resource for urban development. It is one of the key issues of urban development to capitalize on the multi-dimensional landscape service attributes and values of the lakeside area to realize the co-prosperity of lake and urban area. Based on the in-depth analysis of the characteristics of the lakeside area, this research proposes a multi-dimensional value system of the landscape service of the lakeside area, including the value support dimension of ecological safety, the value attraction dimension of environmental quality and the value orientation dimension of functional format. From the three dimensions, the research studies the south shore area of Suzhou Shengze Lake by comprehensively utilizing multi-source big data. On this basis, it puts forward relevant development strategies such as the bottom line of rainfall and flood control, the characteristic of “pearl-necklace landscape” and the layout of the co-prosperity of lake and urban area, and discusses the management and control over the development of the lakeside area.
