Land Use Response Mechanism Caused by Geological Disaster: Taking Mianzhu City As an Example

Geological disasters cause land damage and water and soil loss. This paper carried out the land use response mechanism of the earthquake in disaster-prone area of Mianzhu city in Wenchuan earthquake and its recovery periods. Based on GIS, RS technology and geographical statistics method, the distribution law of geological hazards were analyzed.The response mechanism in the structure, the amplitude, the speed and the degree of land use, the seismic intensity, the water and soil loss and the land sensitivity caused by geological hazards was explored from both macro and micro dimensions. The authors summarized some research methods of land use response to geological disasters and also put forward some measures to rationally utilize land in the disaster area.
