摘　　要：本文是一篇关于全国崩塌滑坡泥石流分布图编制方法探索的论文。基于全国崩塌滑坡泥石流数据库,根据图面承载能力,用不同灾害类型之间数量比例和网格密度共同控制的方法,筛选出代表整体发育分布规律的崩塌滑坡泥石流隐患点;用点状符号表达崩塌滑坡泥石流隐患点空间分布特征,线状符号表达崩塌滑坡泥石流时间分布特征,面状普染色表达崩塌滑坡泥石流发育数量分级特征;结合人们正常视觉感受,建立均衡的构图,选用协调美观的色彩,合理处置图上点、线、面各图层之间的冲突以及图层内部分级关系,编制集科学与艺术为一体的全国崩塌滑坡泥石流分布图。This paper provides a summary map compilation method on the landslide distribution. Considering the capacity of presentation,only parts of hidden danger points of the slides,collapses and debris flows in the database,which are sufficient to show the regulations of the major distribution in China,are selected and presented in the map. The selection methodology is controlled by the proportions of each geo-hazard category in database and grid density. Dot symbols represent the space distribution features of landslides; line symbols represent the time distribution features of them; plane colors represent the grading characteristics of quantities of them. Considering the human＇s visual perception,the diagram of landslides,collapses,and debris flows in China is generated by well designing and balancing graphic elements, using of harmonious colors and appropriately solving conflict relationships between various layers.
