There are many different factors affecting overland flow
such as climate
geology and vegetation
among which vegetation type is a key factor. In this study
four different vegetation types in J inyun Mountain
Chongqing City
were investigated using the grey rational degree. The analyses of precipitation and vegetation ef2 fect s on overland flow indicate the highest rational degree of precipitation with surface runoff. The parameters contribute to overland flow in the descending order of canopy density
standing foresTheight
litter thickness
slope degree
coverage and soil thickness. The rational degrees of different vegetation types descend in the order of mixed wood
