| Abstract: | It is pointed that the porduction and development of gravitational erosion in the store region of the Three Gorges are controlled by regional geology, by means of environmental geology with geotechnology. Then, the basic pattern and stability criteria of the gravitational erosion in the store region of the Three Gorges are established. Then accordingly, the stability region of engineering geology is divided and analysed. On this basis the evaluation of the influence of the gravitational erosion in the geological environment in the store region of the water conservancy project in the Three Gorges is discussed. Finally, the function of gravitational erosion on the production, development, changes, vanishing, scale, effect and distribution pattern of the cities in the store region of the Three Gorges is stated, which is important for the development of the cities and mountain areas and their economy. |
