Main types of geological disaster in Lujiang segment of Nujiang are landslides, slides, mud-rock flow, unstable slope, active gullies and so forth. Among of them, mud-rock flow, slides and unstable slope are the most important. Based on field investigation and statistics analyses, it indicates that mud-rock flow mainly occurred both west and east sides of Nujiang and showed different distribution, controlled by tectonic. Distribution of slides has close relationship with human engineering activities. Atmospheric rainfall is important inducing factor of geological disasters which occurred frequently in rainy years and rain season of every year, and human's unreasonable engineering activities brought out occurrence of them.
