在搭帐篷之前，必须仔细勘察地势，营地上方不要有滚石、滚木以及那些风化的岩石，尤其是靠岩石壁越近的地方越要留意，尽量要避免在凹状的地方扎营。营地不要选在离泥石流通道太近的地方。许多石块有被泥土包裹的痕迹，这是识别发生泥石流的主要标志。雷雨天不要在山顶或空旷? Before setting up the tents, the terrain must be carefully surveyed. There should be no rolling stones, rolling logs and weathered rocks above the campsite, especially the closer the rocky walls, so try to avoid camping in a concave place. Do not pick the camp too close to the debris flow passage. Many of the stones have traces of dirt wrapped around the earth, which is the main hallmark of mudslides. Thunderstorm days do not be at the top of the mountain or open?
