摘　　要：依据模糊聚类与粗糙集的相关原理,通过对单要素指标数据的抽样量化分析,合理确定综合指标中各单要素指标影响系数,标定公路自然区划综合指标分析模型.利用该方法得到海拔高程、地形坡度、地表切割深度、地表切割密度在公路地表形态指数分析模型中的影响系数分别为0.281,0.301,0.225,0.191,据此绘制的中国公路地表形态指数分布图能够正确反映中国不同地区的地表形态对公路建设的影响程度.实例分析结果表明,该方法提高了公路自然区划指标分析的量化程度,实现了对基础空间数据的优化利用.Based on the theories of fuzzy clustering and rough set,this paper put forward the method to reasonably determine the influence coefficients of single elements and calibrate the analysis model of comprehensive zoning indices through analyzing the calculation elements data by random sampling method.Highway surface configuration index（HSCI） was analyzed with this method and got the influence coefficients of altitude,terrain slope,depth of landform incision,density of landform incision that were the calculation elements in analysis model of HSCI,they were 0.281,0.301,0.225,0.191 respectively,then calibrate the analysis model to calculate HSCI of China.The map of HSCI reflects the influence degree of surface configuration on highway engineering in different regions of China correctly.Analysis result shows that the method improves the quantization degree of comprehensive zoning indices analysis,realizes the optimal utilization of the fundamental spatial data.
