In Hailuogou, a famous landscape, there is a close relationship between the ecological phenomenon and the evolvement of geological environment. Many natural hazards or unnatural disasters happened because of the rapid growth of population in this region. The authors carefully evaluated the geological environment, and analyzed the particular geology characters in this region. As a result, a series of prevention measures of disasters are brought forward for the further development of the region. According to the field investigation, the main geological problems included snow avalanche, glacier avalanche, frost bursting, creeping slip of rock and soil, falling, landslide, debris flow, soil erosion and earthquake, and the reasons for these problems can be concluded as following: (1) the upward risen of the neo tectonic movement is very strong. (2) the geological structure system is quite complex. (3) the effect of glacierization is rather clear. (4) the heavy precipitated water often happens. (5) human activities are very frequent. At last, for protection of the geological environment in the area, the authors raise three pieces of advice. First, evaluate the stability of the slope in section 1.Second, control of falling and debris flows and exploit thermal springs in section 2. Last, plan a channel for the drainage of debris flow in section 3.
