Abstract:Aiming at the variation of the main soil fertility factors in alternate years of the base material for vegetation concrete eco—
slope protection,the base material soil samples are taken from four sample plots,and then the analysis of quan titative determination
is made on the main soil fertility factors of the vegetation concrete in the alternate years(2008 and 2009).Simultaneously,a con—
prehensive evaluation of the physieoehemieal properties is made on the fertility levels of the four sam ple plots based on the standard
integrated grade method.The result shows that except the sample plot No.2,all the index values of the soft fertility of the vegetation
concrete base material from the other sample plots exhibit increasing trends within a cycle of one year,moreover,the fertility levels
in adjacent years of all these sample plots present the increases in alternate years:which provide a better nutrient level for the SUS—
tainable succession of the soil fertility of the vegetation concrete and the long-term stable growth of vegetation.
