| Abstract: | Twenty indices of grass properties were analyzed through analytic hierarchy process (AHP) under mid tropical zone. The result showed that there were some important indices were drought resistance, coverage, aboveground biomass, tolerance to barren soil, belowground biomass, cold resistance, green periodand root length. The comprehensive adaptability of the grasses was analyzed through AHP in the experiment about 4 species legumes and 19 species grasses on the slope of highway in the area of weathering purple sandy rockregion. |
