China is a country with complicated topography landforms and geological disasters widely distributed, and is one of the landslide-prone countries in the world. As landslides and debris flows are of harmful natural disaster type to human being, the effective real-time monitoring on landslides become very important. The landslide monitoring instruments are often being damaged because the most are installed in the mountains where few people live or being uninhabited, and what is more, the people have less awareness of geological disasters monitoring. Based on the landslide monitoring projects in Danba County, the paper summed up the experiences of the field installation and the protection of landslide monitoring instrument.
