A Study on the Spatial Characteristics and Endogenous Logic of the Dong Ethnic Settlements in the Pingtan River Basin
The Dong ethnic settlement is an important material carrier of Chinese regional civilization.It is of great significance to the protection and inheritance of culture to clarify the spatial characteristics and endogenous logic of internalization in the settlement.Taking the Dong ethnic settlement in the Pingtan River basin as an example,using GIS spatial analysis,boundary shape index,and spatial syntax,this paper analyzes the location,external boundary and internal structure of the three main elements in the generation of settlement space,from the overall spatial distribution of the basin and the environmental structure of the village space to the spatial morphological characteristics of the village,and discusses the logical relationship of internalization in space.It shows that:1)The Dong ethnic settlements show obvious spatial agglomeration characteristics,forming the characteristics of dominated by near water villages,living in the middle and upper reaches,and distributed along the linear water network in the basin.2)The overall settlement scale presents the three-dimensional environmental spatial characteristics of"mountain,forest,village,water,and field",but there are obvious differences in the spatial morphological characteristics of different spatial types of settlements.3)Under the influence of the landscape pattern,the settlement boundary forms are mainly finger-shaped and belt-shaped;in the settlement,the interior forms a space with the drum tower as the core to lead the development of the village,and there is obvious hierarchy and order.At the same time,the quantitative values of the settlement form characteristics of different space types have obvious range.4)The settlement space presents diversified spatial characteristics in the dynamic induction of three logical mechanisms of adaptive ecology,self-organized society and self-survival and development.On this basis,strategic guidance for the protection of watershed settlement space is proposed.
