Analysis on Amount of Gravitational Erosion in Jinsha River Basin of Yunnan Province
【Abstract】 The amount of gravitational erosion is an important part of the total amount of regional soil erosion, thus it is an indispensable important content of investigation and study on soil erosion. Taking Jinsha River Basin of Yunnan Province as an example, the paper has probed into the measuring and calculating method of regional gravitational erosion amount (including the total amount of eroded rock and soil matter and soil erosion amount in it). According to the data of landslide (including collapse ) and debris flow investigation and study in the Basin in the past, and combining with the on the spot survey of typical landslide and debris flow examples, which has calculated every county and the whole of the Basin of the average annual total matter amount of gravitational erosion and soil erosion amount in it on the basis of delimiting every county of all parameters of calculating gravitational erosion amount, and analysed the main characteristics of the gravitational erosion amount in the Basin.
【Key words】 gravitational erosion； landslide； debris flow； amount of soil erosion； Jinsha river basin；
