| The citific development brount modern city and urban architecture extensive and profound transform, so the old urban constructional patterns have couldn't adapt to the developmental need of the age. The stereoscopic, indoorsic of urban design and the synthesization, socialization of urban architecture make the boundry between city and architecture misty increasingly. And the urban space exsits with the architecturcal space two level of structures to permeate more and more with reunite. The academic theories and the development of the design practice indicate that the interaction design of the city and buildings of synthesize will become the development trend of the future urban buildings. The modern urban building, particularly the large and public will play an inceasingly important role in the future urban space system, under the background, this text brings forward the concept about the compound pubilc space and takes it as research object.The compound pubilc space is an architectural space that can undertake the city working talent, get involved and affect the public space in city system space through opening to the city public in the modern urban architecture. The part of space belongs to the field intersected and bestrowed by architecturcal space and urban space, is provided with the diplex spacial attribute with architecturcal space and urban space, combining to undertake the dual space working talent.In combination with plentiful domestic and international example,this text distinguishs from four aspects to reunite the public space to proceed the research, At the fiest Chapter,the article expatiate the basic concept of thr compound public space.Chapter 2 expatiate the development process, and Chapter 3 type expatiate the analysis etc. Chapter 4and Chapter 5 belong to research of designing method, among them chapter 4 from reuniting compound public space oneself space constructing or purchase proceeds the research .It puts forward to the basic principle that compound public space design should follow, then handles from the spacial appearance, the spacial layout, spacial designs main factor etc. as it's design the method proceeds to induce with tally up, and choses the five kinds of reuniting the further study in proceeding in public space form most typically;Chapter 5 studies the manner combinated with the compound pubilc space and the city, including with the combination of the urban transportation system, with the structural combination in urban space, with the combination of the city environment context threeaspects,then puts forward in a specific way and homologous design principle aim at every aspect.Thesis studies the compound public space and its design from the architecture in combination with the city.As a way of alleviating the antinomy about the city and the architecture,urging the two organism to join together,the compound pubilc space is a new request of the architectural spatial creation put forward from the city. Leading into the city consciousness for the building design, it also puts forward own standpoint and method of the city design from the architectural. Its research result inspires to the artistic design of the modern city building ,design strategy summarized and put forward in the realistic design fulfillment has the much value use for reference. |
