Quantitative Study On The Plane Form Of The Twelve Capitals In Yixian County

Of all the six counties in ancient Huizhou,Yixian county,with a long history,retains the traditional village form and is of high historical value.During the Ming and qing dynasties yixian county administrative region is divided into twelve,twelve is today’s central village as the research object in this paper,from the perspective of relationship between the bottom is the whole of village space form into village space,public space and architectural space at three levels,by using the methods of landscape ecology,fractal geometry to the village texture and morphology of scientific system of quantitative research.In addition to the abstract description,it is expected to provide more specific quantitative analysis,excavate the spatial texture characteristics and internal laws of villages,assist the protection and renewal of villages,and promote the inheritance of village forms.The external boundary of Yiidu village was quantitatively analyzed,and three different virtual boundary scales of 100 meters,30 meters and 7 meters were used to set the closed graph of village boundary.Village shapes can be divided into three types according to the ratio of long and short axes and boundary shape optimization index.The boundary characteristics of twelve cities are studied by boundary density,dispersion and average width of outer edge space.The spatial structure of the village is quantitatively analyzed.Calculate village building density and building core density,get building coverage and distribution map.The interior space of the village is divided into two parts: courtyard space and public space.The courtyard space relies on the building and calculates the courtyard space rate by the area defined by the building contour.For the irregular public space,the fractal theory is adopted to expand the village boundary by 2.5 meters to obtain the continuous public space map spot,and the fractal dimension value of the public space is calculated to study the degree of structuration and complexity of the village.The quantitative study on the spatial form of villages can draw the following conclusions :（1）after quantifying the closed graph of village boundary,village shapes can be divided into three types: free village（cluster tendency,no clear expansion tendency）,cluster village（band tendency,no clear expansion tendency）and banded village.（2）After quantification,villages are divided into three types: low density,medium density and high density.The courtyard space in single building space is quantified,and villages are divided into three types: low courtyard rate,medium courtyard rate and high courtyard rate.Village public space is quantified into three types: low fractal value,middle fractal value and high fractal value.（3）According to the quantitative results and the actual situation of Yixian County,yixian County is dominated by cluster villages with strong border closure,tight construction land and poor spatial structure.In village construction,we should attach importance to boundary space,respect natural environment,continue traditional village spatial organization form and courtyard combination form,and use rational tools to protect village texture.Figure [52] Table [25] Reference [68]...
