Abstract:Western classical gardens have a profound impact on the modern landscape development. This article adopts the deductive argumentation research method, takes two French classical and modern landscapes, Estate of Marly and Parc André Citro?n, as examples, to compare and analyze differences in the spatial composition of Western classical garden and modern landscape. The article demonstrates the internal relationship between Western classical garden and modern landscape from three dimensions: site and space, spatial structure and organization, and spatial form and composition.
