Abstract:

A huge number of traditional settlements in China represent their outstanding values in such fields as economy, society, and culture. It is notable that researches on traditional settlements will help to promote the sustainable developments of economy and society currently. Lately, a new tide of research on the traditional settlements, stimulated by the new urbanizing strategy, is arising across the entire country. This paper mainly focuses on the methods in deriving the spatial forms and structural patterns in the traditional settlement landscape genome maps (TSLGM) by case studies of Hunan Province (located in the middle reaches of the Yangtze River and south of Dongting Lake in China). Firstly, this work defines these five types as centralized-circular rings, pie-extensions, multiple-direction extensions, belt, discrete distribution, and blocks, respectively. The five basic spatial form types are spatially driven by their pertinent landscape genes' spatial sequences of the genome by map analysis. Mathematic features of the form types are derived by their structural details and related properties. Secondly, the mathematic features are further used to help draw the spatial structures of the Hunan Province's traditional settlements incorporated with the related landscape genomes by the supporting-field from the Spatial Syntax Theory. Deep comparisons of different spatial structured cases prove that the mainstream spatial structures of Hunan Province's traditional settlements are symmetry, boundary, street-alley-port, parallel, geomancy image, respectively. It is shown that the spatial morphology properties of the traditional settlements derived by TSLGM are helpful in improving the traditional settlement landscape gene theory, refining the understanding values of traditional settlements and forwarding the preservation progresses on the traditional settlements. More importantly, this work confirms that TSLGM is a very promising method in mining the geographical features from the traditional settlements and establishing the regionalization framework across the whole country.
