The Research On Landscape Reconstruction Of Old Urban Area Under The Background Of Urban Renewal

China’s urbanization construction is growing faster and faster,and many old urban areas cannot meet the diversified needs of residents.As a result,a variety of problems will appear due to a long time of unsolved,including no good regional function,poor living environment,no reasonable layout and the decline of traditional characteristics,etc.It is necessary to inherit and carry forward the traditional urban spatial structure and style,optimize the environment and equipment and facilities,improve the comprehensive function of the old town,and effectively renew and reform the old town.Only in this way can the sustainable development of urban society and economy be maintained.At present,China’s urban construction is no longer carried out in accordance with the former form of overhaul and repair,but based on urban renewal to carry out "micro" transformation.Combined with the reconstruction case of Bagua Street in Shenyang city and the results of field investigation,the paper finds the existing problems in the old city and seeks solutions to optimize the living environment of residents in the old city as far as possible,hoping to provide help for the effective integration of urban development and old city.Before the old city renovation in our country,from the beginning of the old city reconstruction of macro evolved for residents living environment,however,few studies have old micro reform achievements of theory and practice,the old city renewal has been at the same time,relevant staff did not accurately know the old city transformation,so it is need a sound legal system and relevant theories.Based on streets,lanes,space,culture and green space,this study summarizes and analyzes old city reconstruction under the guidance of urban renewal theory,and finally draws the following conclusions:First,urban renewal,concept and cultural transformation.In the process of urban reconstruction,the concept of reconstruction is reasonably used to guide the integration of idle urban land,but the core point is to fully respect the context of the old city.Second,urban renewal concept space transformation.Space transformation is carried out under the guidance of space form,scattered Spaces in the old city are integrated through corridors such as streets and lanes,and the principle of walking first is always followed,so as to construct the artificial but shaped old city space layout.Third,the concept of urban renewal street transformation.The traffic function of the road is adjusted to effectively link the various alleys along the line,and the overall planning of scattered streets and alleys increases the function of the old city streets and alleys on the basis of retaining the original style and culture of the streets and alleys.Fourth,the transformation of urban renewal concept square.The public space is used to connect the open square space in the old city.After combining various functions,the streets can be more convenient and have diversified functions.At the same time,a multi-functional community service place needs to be built.Fifth,the concept of urban renewal and architectural transformation.Old urban areas need to be divided according to the rebuilt architectural style,and historical characteristic elements should be integrated into them,so that the original disorderly streets can be transformed into characteristic commercial streets after rectification,so as to show the charm of the city’s historical image.Sixth,urban renewal concept green space transformation.Under the guidance of the concept of urban renewal,the green space is transformed to effectively connect the scattered green space,so as to build an integrated green space system,improve the urban climate,and ultimately optimize the landscape background and grade.Urban renewal theory can be used to guide the reconstruction of streets,squares,culture,buildings and space in the old city,which means that the urban renewal theory of the old city reconstruction is operable,but also can provide help for the theory and practice of the old city reconstruction later.
