《"Landslide integrated characteristics and susceptibility assessment in Rongxian county of Guangxi,China"》
The samples of landslide presence and landslide absence can be selected from grid data.The selection criterion is that the number ratio of two samples is approximately equal to 1(Ayalew and Yamagishi 2005).In study area,772 samples with landslide presence and 798 samples with landslide absence are selected.Because LRM has an automatic function of selecting factors,the factor that has little contribution to landslide can be excluded from the model(Ayalew and Yamagishi 2005;Budimir et al.2015;Devkota et al.2012;Lee and Pradhan 2006;Park et al.2013)Then the logistic coefficients of each category can be calculated by the statistical software SPSS20(as shown in Table 8).These coefficients are put into Eq.(3),and the P of each grid unit is obtained.In this research,the range of P is from 0.064 to 0.982.The range is divided into four intervals as follows:0.06~0.2(very low),0.2~0.4(low),0.4~0.8(moderate),0.8~0.982(high).
