Abstract: According to the field investigation of many landslides in loess area,the loess landslide,strewed by moving modes,can be cognized to four typical types:collapse landslide,high-speed distant landslide,low-speed creep landslide and landslide mudflow.Take four typical loess landslides for example,the forming conditions and the kinematics characters of all manner of landslide are analyzed respectively.Space forecasting index,affect causation and modeling idea have been built responding to four kinds relatively under their moving modes.It provides a main thinking way of space forecasting of landslide disaster in loess land and it is also the base of forecasting academic modeling of landslide.
