The Research On The Temporal-spatial Distribution And Spatial Quantificztion Of Ancient Settlements In Songhua River Basin

Settlement has a high cultural and historical value as the carrier of human habitation culture,however,the ancient settlment in Songhua River Basin have not given a sufficient attention and systematic study due to the scattered ecological elements and its special location which is on the edge of traditional culture center.Because of the superposition of the traces of different ethnic activities in different periods,Songhua River has a special and diversified cultural foundation and heritage,which is of high research value and needs to be studied and protected.This paper make a preliminary study of the ancient settlement of Songhua River Basin based on the results of archaeological excavations,relevant interdisciplinary methods are used with the help of GIS technology,in order to analyze the temperal-spatial distribution and morphological characteristics of ancient settlements in Songhua River Basin,and provides the basis for realizing the sustainable protection of its heritage value.Of songhua river basin of the ancient settlement development vein combing and analysis of time and space distribution,in the songhua river basin of the natural environment,historical evolution and the dominant cultural forms are studied,on the basis of establishing the songhua river basin of the ancient settlement spatial database of historical evolution in the basin and comb,quantitative description of each period settlement development and distribution,and draw the different period of the settlement space distribution,through the settlement distribution in different historical periods and the historical map overlay,visual expression of songhua river basin ancient settlements development and quantitative analysis,intuitive graphic showing its development process and characteristics of regional distribution.On the basis of elaborating the development course of the settlement in the basin,the periodic summary is carried out to analyze the spatio-temporal evolution characteristics and the driving force of the spatio-temporal evolution pattern.The quantitative analysis of the spatial characteristics of settlements is mainly carried out from three aspects: firstly,the statistical analysis of the elevation,slope,slope direction,buffer zone away from water and buffer zone away from mountain in each period of ancient settlements is carried out to study the influence of different influencing factors on the site selection of settlements;Secondly,a spatial index model was established to model and analyze the settlement space,and the optimal distribution of the settlements in different periods was studied.The optimization results obtained from the multi-objective comprehensive weighted analysis were compared with the actual distribution of the settlements,and the rationality and reasons of the settlement distribution were analyzed;Third,through the horizon,the resource domain analysis of settlement composition form,parameters,such as reference in the basin during the same period,archaeological data reconstruction of social and economic relations between different groups,to discuss the economic morphology change,the influence of the dominant culture form of settlement,so as to explore different period settlement site structure form and spatial characteristics and the connection between the dominant ethnic cultural value system,fill in the architectural history perspective of the studies on the ancient settlements in the songhua river basin under the blank,improve the cognition to the development of Chinese traditional settlements.
