Due to complex climates, geological conditions and landform types, the ecological environment in the western region of China is very fragile. Thanks to the continuous large-scale construction of highway transportation infrastructure over the years, the social transport services are satisfactorily offered in the western region, but also some negative impacts on the ecological environment in the western region are accompanied, especially a large impact on the land resources in extreme scarce in the western and weak soil & water conservation in loess region. The western loess region faces low land bearing capacity, fragile ecological environment and severe soil & water erosion. Restricted by its own conditions of the spoil disposal site, in the case of lack of rainfall and loose soil, it is very important for later restoration to accurately learn the hydrological characteristics of the spoil disposal site.
