资源简介：

Runoff axes are the steepest slopes, so they are the place of rainwater flow during runoff. Then can spill water and sludge and there is the risk. A first campaign to detect these axes was carried out in the 1990s on the basis of the IGN map at 1/25000.

径流轴（Runoff axes）为坡度最陡的区域，亦是降雨径流过程中雨水汇流的通道。此类区域易发生漫水与泥沙淤积，存在安全隐患。首个针对此类径流轴的探测工作于20世纪90年代开展，数据依托比例尺1:25000的IGN地图。
