Study On Shanghai’s Outer-Ring Expressway’s Linear Greenbelts And Its Flanking Park’s Green-Space Ecological Landscape

China’s urbanization process is accelerating day by day because of the continuous expansion of urban construction. The hysteretic model of city’s green-belt road construction becomes the restricted factor in the development of ecologically coordinated relationship between the urban area and the suburban environment.This paper based on the case of Shanghai’s Outer-Ring Expressway’s linear greenbelts and its flanking park’s green-space ecological landscape, aims to achieve the ecological sustainability of Outer-Ring Expressway’s linear greenbelts according to the perspective of ecological footprint horizon, improve the quality of urban environment. From an interpretation of this concept to the summary and apply of learning from aboard model, this paper provides a reference idea for the planning and construction of urban green landscape.This paper uses literature resource method, example survey method, through analyzing field research and studying technical route, starting from the rational elaboration of abroad road pattern theory and modern Beltway roads greenbelt. What’s more, the paper recalls representative of western modern-Ilir· Saarinen’s, practicing organic evacuation planning ideas, purposing on following the law of urban development from the angle of spirit of urban space. Shanghai Urban Planning in history used such advanced urban planning theory like "regional planning," satellite towns "," neighborhood unit"," organic evacuation ","expressway", especially got huge impact of the Greater London Plan chaired by Alber Crombie, also, there’s a connection between the modern western greenbelt theories and ecological environment of the entire Shanghai’s ring road’s domain-wide framework.I chose Shanghai Outer Ring Expressway roads greenbelt planning as an analytical case, then analyzed greening design of the main roads on both sides of the shoulder, slope, fence greening, greening and other roads interchange construction, also, I apply the imagination of "long cane fruiting" to the Outer Ring roads greenbelt which is involving eight districts across segments Garden. These analyses and applications of the design of sight of district, garden, sequence and scene point form a linear greenbelt landscape structure. What’s more,1selected a typical countryside garden---Gu Village Park, to purpose a conceptual plan and carry out the theme of the area attractions landscaping plans. After these three project cases,1put each segment into a line, and gather points into a string, from the regulation of established topic to each functional area and the segment’s site planning, spatial flow lines, the scene rank and the scene order of the visual analysis, the use of the various elements of the garden landscaping attractions dimensional scene creation, the landscapes of them are following ecologically sustainable environmental principles throughout the meantime.The formation of shanghai outer-ring greenbelt road relate countryside style green ring and various types of urban green space in series, at the same time, this formation stretches the green core, green heart green wedges, green axis, Green Island and other forms of urban core green area to the whole range of the urban through the way of linear pergola, further more, the multiple surrounding areas green would band together to build a large Shanghai domain-wide green ecological network. In all, we can get a conclusion that from analyzing and planning the outer Ring expressway greenbelt road, we can attempt to build the entire urban green belt road and the flanking park landscape construction, even to prompt to use at the whole Yangtze River Delta region.
