摘　　要：采用模糊推理思路构建了专家知识库,将地形、道路等级、长度、坡度、曲率等影响因子定量化,弥补常规路径分析方法中忽视空间实际地形地貌等因素的不足,由于知识具有普遍性,将方法移植到其他地区也能够适用。该方法应用到山西沁水盆地柿庄南煤层气开发示范区的地面集输系统中,实践表明,该方法能够满足巡检决策的需要,具有一定的实际使用价值。This paper introduces a fuzzy quantitative analysis method that is comprehensive consideration of terrain,road grade,length,slope,curvature and other impact factors to determine the weight values of the road link based on theory of fuzzy inference and expert knowledge,which makes up for the ignorance of lack of spatial geographic information.Because knowledge and expert knowledge are universal in the world,the method can be applied to other areas.The way of fuzzy inference is applied to coal-bed gas surface gathering system of Shizhuang demonstration area in the southern of Qinshui Basin,which can meet the needs of the daily patrol decision-making.Practice shows that this study has some practical value.
