Abstract: Quantitative Theory Ⅰ was applied to evaluate the influence of managing measures on the relationship of pasture grass and weeds on two typical grasslands of south China.Grazing intensity and fertilizer dosage were the key factors affecting the dominance of pasture grass.The main weed species were E.odoratum,E.rubiginosum,H.perforata,I.anlindrica and E.annua.The suitable density of cattle was 1~4 cattle·hm-2,and the dosage of fertilizer application was 500~1000kg·hm-2 for superphoshate,and 150~250kg·hm-2 for KCl.
