Spatial Morphology

With reflection on the spatial morphology continuity of water towns nurtured in the environment of Jiangnan (south of the lower reaches of the Yangtze River), the writer analyses, on the basis of analysis of the prototype elements which constitutes the spatial morphology of the water towns, the characteristics and reasons of the spatial morphology evolution of modern towns and finds that it is an operational method to restore the fragmented morphology starting from the archetype elements, thus putting forward the idea of restoring the ecological corridor of water network, integrating folk house architecture and returning the street to a humanity space.

With the rapid development of city, many large and medium-sized cities sprawl in urban space,triggering a series of socio-economic issues related to land-use. Based on RS and GIS, selected Kunming as study area for its typical representation of Yunnan plateau mountain cities, used the method of spatial quadrant orientation analysis, obtained the number and structure of construction land expansion in specific direction of study area in period of two different years, and calculated the intensity index and fractal dimensions of the urban expansion. Finally, according to local conditions, spatial expansion variations features of Kunming were analyzed systematically.
