The City Of "Grey Space"-the Landscape Space Exploration Under Overpasses

Global urbanization shows more and more quick pace the trend of modern citycarries, growing population, material and information and culture and people to theecological transition consumption, followed by people to face the survival environmentof malpractices appeared. Global warming is give us was a wake-up call, its disastrousconsequence will be a direct threat to the survival and development of human beings.But modern social development of industrialization in energy use and emissions ofgreenhouse gases, the contradiction of it is inevitable. China as energy consumptionmore countries in December2009, one of the Copenhagen climate conference called onthe international community to assume "common but differentiated responsibilities andpromised to" in2020unit of GDP than carbon dioxide emissions40%~45percentdecline in2005. If want to in such a short time to reduce co2emissions to large-scalethe goal, in the future, China must vigorously develop the low carbon economy.We’re doing one of designed to change now is the urbanization mechanism, make itbetter realize the sustainable development. Gradually subsided20th century oldtraditional growth mode, convert the new century innovation technology and innovationmechanism, in this premise, low carbon technology, low carbon economy mode and lowcarbon life as well as a series of new concepts and new policies springing up arises atthe historic moment. For gradually toward ecological civilization out of a new road, thisalso is energy and economic and values the inevitable result of a big change.The emergence of overpasses is undoubtedly urban development a clear context. Itin the city and communication of world civilization, but also in communication with itsunique glamour belongs to its own unique won attention. It was the first to have at thesame time the structures functionality and esthetics working together. Its not only solvedthe problem, car shunt more become city beautiful scenery line. But the city at the sametime, these useful structures of subsidiary facilities and its affiliated space and not givenproper attention, even wasted a lot of very unique charm of the original form of thespace. These problems are all the ensuing bothering designers in the eye.This paper, starting from the city image level in urban public space and landscapesystem based on the background and analyzed and discussed the development process, city flyovers dimensional existence the basic types of, landscape features, landscapeeach element of the characteristics and design. Emphatically analyses the generalfeatures of the overpass landscape node, such as energy, becomes to notice thedistinctness intellectual, suitability, accessibility, control, efficiency and fairness, etc.Through the written material and field data, clear contrast of the north and south regionof domestic cities under overpasses the landscape design differences. Make existing inthe current city overpass the oneness on the design to change, and reinforce present cityoverpass and city of various factors relation, rationality.
