摘　　要：运用数量化理论I评价了华南地区两个典型人工草地中人工管理措施对牧草与杂草关系的影响.结果表明,放牧强度对东方示范牧场的牧草优势度、施肥水平对粤北第一示范牧场的牧草优势度有重要的影响,其主要危害杂草分别为飞机草(E.odoratum)、赤才(E.rubiginosum)、牛筋果(H.perforata)和白茅(I.anlindrica)、一年蓬(E.annus),并确定其草地适宜载畜量为1～4头牛·hm-2,适宜施肥水平为过磷酸钙500～1000kg·hm-2,KCl150～250kg·hm-2.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.
