Application of Multiple Nonlinear Regression Based on SPSS in The Risk Assessment of Debris Flow

摘要

This article establishes analysis model based on Multiple Nonlinear Regression and analyses the model using SPSS. Then eight indexes such as storage of Material sources are selected as independent variable, and make an empirical analysis by survey data of 40 debris flow valleys. Finally, the test results show that both the importance analysis of the impact factors of debris flow and the rank deviation of risk assessment are right. Moreover, using multiple nonlinear Regression model and SPSS to assess the risk of debris flow is proved feasible.
