    摘要:

    从1452处环嵩山地区史前聚落中随机抽取所占比例为60%的聚落,用于聚落选址偏好等级划分。利用GIS空间分析技术,讨论聚落分布与海拔高度、坡度、水系、地貌、土壤、气候等6个地理环境因子之间的关系,利用变异系数法确定各指标因子的权重,引进空间加权叠加法构建史前聚落选址偏好等级模型,将研究区划分为3个史前聚落选址的偏好等级区,即高、中、低。利用剩余的40%的聚落进行验证,结果表明模型精度比较高。结果可用于对环嵩山地区未发现的史前时期聚落可能存在的地理位置进行预测。

    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.
