Spatial Cognition Research Of Nodes Of The Core Urban Area Of Kunming Based On The Theory Of The Image Of The City

With the increasing pace of urbanization, the city carries a highly concentrated population, material, information, cultural and ecology, and it brings convenience and disadvantages to the existence of human. The Urban public space is increasingly becoming an important subject closely related to human. In cities, urban public space nodes play a vital role. In addition to organize the daily life, it also carries the heritage of the urban culture, meeting the requirements of tourism, and it is an important element of the overall image of the city. In recent years, the image of urban space in China is gradually on the rise. Using the theory of image of city to analyze the urban space is a method to modern urban space research. Compared with the other methods, the main advantage of the image of urban space is that it values the cognition of the city residents to the urban space environment, While cognition is the basis for behavior decision. Cognitive research becomes one of the methods commonly used in urban design and urban planning to get the social data related.This essay explores node space from the perspective of cognition, based on the image of the city theory, and combined with the cognitive theory. The essay studies the node space from the perspective of macro layout and micro cognitive analysis in spatial cognition research. It studies the cognitive distribution of nodes with the methods of cognitive map and site visit in macro layout. It comes out that the cognition status of the nodes in the core urban area of Kunming reflects three features: first, area of cognitive imbalance, cognitive concentration; second, clarification of traditional image; third, elements vivid. The analysis indicated that the cognitive status was affected by historical context of the city, commercial factors, the accessibility of the node and other comprehensive factors. Then, basis on the cognitive layout and features, it classifies the nodes into the history nodes (the nodes have been well developed),the developing nodes (the nodes need to be constructed) and the future nodes(the distribution of the nodes influenced by the urban subway) according to the distribution area of the nodes and its development sequence.In cognition research of micro-node space, it investigates the awareness of the node space mainly using the methods of photographs plus maps and on-site interviews. It summarizes and details the image elements of micro-node space:mark, region, center, road, entrance and boundary basis on the theory of the image of the city, and it also generalizes the elements of the nodes effect on the cognition of urban node established. Then, it analyzes cases of micro-node space by classification, combined with the image elements of micro-node space. It locates the characteristics and style of urban nodes and it proposes a planning guide to the design of micro-node space from the perspective of the general population, so as to enhance the public perception of the nodes.Finally, on the basis of this research above, it gives some suggestions to the construction of Kunming, the element road closely linked with the node, the distribution of node space of Kunming and the six elements of the micro-node space.
