Integral Conservation Analysis Based On Spatial Syntax Method

The essential and central issue of this dissertation is to present countermeasures on heritageconservation in Changsha historical urban area by analyzing its morphology evolvement and evolvingreasons based on the subject of returning space ontology. Meanwhile, the research methodology andperspective of studying from morphological evolvement to formation change mechanism of historic urbanis also central issue which has been continuously cared. As the result, this paper followed the researchmethodology and perspective, but on crucial path analysis, a relatively new methodology called spacesyntax theory and its technique platform derived from urban spatial morphology are used to solve someessential and difficult questions which are concerned with heritage conservation of historical urban. Inorder to solving these questions, the summary discussion of this paper is four aspects:Changsha city as the case example, the feature of form evolvement was deeply analyzed, with whichcompared the features of city’s downtown displacement, the part-whole synergy relationship of city space,spatial agglomeration and diffusion from1872to2010. Then, after comparing the features of city formevolvement with its potential cultural implications, the mechanism of spatial form of self-organization andheter-organization were summed up. Among these two mechanisms, one of the mechanism called spatialself-organization including form self-similarity, path dependency of spatial expansion was especiallyemphasized to explain a series of rules such as scale threshold theory, selected location theory andunbalanced development theory which have a great impact on historical city conservation.Based on the above mechanism of spatial self-organization, this paper by using space syntaxmethodology to analyze the relationship between spatial configuration, spatial natural movement, and theinfluence of movement economics, to countermeasure the adverse effects caused by single centerstructure of historical city. Therefore, spatial configuration planning based on space syntax morphology canbe used to reduce excessive natural movement and increase the centrality of New Towns which aroundthe historical urban area. And in detail test, an ideal model and other three measures were used to stimulateor prove the result of spatial configuration planning.Besides exploring the solutions on single center structure, this paper tries to continue place sense inhistorical city. By linking place sense of image theory with intelligibility of space syntax methodology,the effectiveness and complement between the two theories were testified, and come up with a spatialself-organization adjustment approach according to spatial sore device mechanism analyzed by spacesyntax methodology.In order to restore the cognitive image links among heritages, this paper advocate a perspective ofcultural planning, meanwhile, combined with visibility graph analysis and EVAS technique included byspace syntax methodology, an integrative strategy was present to link current cultural facilities withhistorical heritages on showing whole historical city’s cultural value. At last, in practice, the coverage ofhistoric urban area and three historic districts as examples were analyzed to illustrate the integrationstrategy.
