Prehistoric Settlement Sites Selection Preference zoning around Songshan area

Abstract:

60 percent settlements were selected randomly from the 1452 prehistoric settlement in area of Songshan culture circle for settlement sites selection Preference zoning. The paper discussed the relationship between the settlement distribution and altitude, slope, river systems, topography, soil, climate by using GIS spatial analysis techniques. Weights of each index factor were calculated by using the method of variation coefficient. Prehistoric settlement sites preference level model was constructed by introducing space-weighted superposition method to divide study area into three classes: high level, medium level, low level. The model was validated by using remnant 40% settlements. The validation results showed that the accuracy of the model was relatively high. The model can be used to predict the geographical location of the settlements that are not found.
