Research Of The Landscape Design Of Urban Portal Hubs Interchange

The hub interchange has become one of the important components of the modern urban transportation system.The overpass space formed by it is part of the urban green space system and also a type of urban public space.Its landscape has also become the main part of the urban landscape system composition content.The advantages and disadvantages of the interchange landscape directly affected the quality of the urban landscape environment,especially the urban portal hub interchange landscape with planar and large-scale landscape features is more prominent.This paper systematically explored the strategies and methods of landscape design and promotion through the integration analysis of interchange landscape cases and overpass space utilization in recent years,and then classified in terms of ecology,recreation,sustainability and vision.The specific landscape response measures have been clarified and have more prominent practical significance.The first chapter analyzed several related concepts of the urban portal hubs interchange model,then analyzed the scope,structure,function and characteristics of the interchange landscape,and clarified its relationship with “the general interchange landscape” and “the urban park landscape”.The difference is based on the theory of road landscape ecology,the theory of recreation and the theory of landscape aesthetics as the basis for the landscape design of the urban portal hub interchange model.The second chapter selected the domestic and international hub interchange cross-view landscape,the interchange attached space landscape design case for analysis,classified the design trends,current problems,and summarized their effective strategies and innovations in ecology,recreation,sustainability,etc.concept.The third chapter put forward the design goals and principles of the urban portal hub interchange landscape,and organized a set of design strategies including ecological,recreational,sustainable and visual aspects.On this basis,the fifth chapter explored the examples and applies the strategies proposed in the previous section to specific practices.
