| Urban development in China has entered a new stage of stock development with the goal of quality improvement,so the focus of urban development has gradually shifted to characterization,culturing,livability and other aspects.Urban characteristics plays a crucial role in improving the quality of urban space and environment,enhancing urban competitiveness and influence.Facing the problem of the crisis of city characteristic and the tendency of construction disorder left over from the period of rapid urban expansion,it is of great significance to strengthening planning guidance on the spatial pattern of cityscape characteristic,so as to make the best use of the positive benefit to the quality of urban space.The cityscape characteristic is the city individuality showed by the urban spatial environment with the characteristic of wholeness and abstractedness,while the region of representation shows the characteristic of patchness.By the perspective of landscape ecology,this paper introduced the concept of patch to deconstruct cityscape.Based on the relationship of the spatial elements,the spatial distribution can be explored.Firstly,this paper reviews the relevant research on cityscape characteristic and the practical cases of special character areas,determines the research perspective of landscape ecology.Secondly,on the basis of defining the research object(cityscape characteristic patches),this paper takes Nanjing as an example to carry out the research.Through the analysis of network data,the image of Nanjing cityscape characteristic patches was selected,and translated on the satellite map.By summarizing relevant studies and planning texts,four types of urban corridor space that are most closely related to the patches are selected,which are traffic artery,river system,open space and cultural sites.Based on the public’s cognitive,this paper analyzes the internal genes of cityscape characteristic,and divides the patches into four types: cultural manifestation,ecological integration,modern guidance and functional carrying.Afterwards,the regularity of Nanjing cityscape characteristic patchness is summarized.Finally,The research results were used in the urban space of Lishui in Nanjing.According to the current characteristics and development needs in the future,the typical blocks in the southern area are planned and guided,so as to achieve the goal of distinctive urban development.This paper provides a concrete and describable cognitive perspective and research model for the system of characteristic features in general urban areas by studying the phenomenon and pattern of characteristic features.Analytical characteristics of landscape patches intrinsic characteristic gene,summarized its and spatial correlation characteristics of corridor space elements,is advantageous to the city characteristics,the readability of the evaluation,guide,to the planning of urban concrete blocks and building community and control has important guiding role,display and control of city characteristic style guide,improving the quality of the urban space has the practical significance. |
