Abstract：This paper analyses the present prediction methods on soil erosion modulus for development and construction projects.It is found that soil erosion modulus in different development and construction projects are related to the relative area of bare earth surface,stability of soil,density of soil and so on.So the factor analytical method which introduced in this paper is decided by both the factors of soil erosion modulus and the data of field observation and dynamic monitoring.The further modification of prediction method for erosion modulus on development and construction projects was discussed.
