Abstract: The growth of Ligularia narynensis in Kalajun rangeland of Yili and its difference of sexual reproduction quantitive characters under enclosure and grazing conditions were studied. The result showed that 1) the important value of L. narynensis synchronously changed with its growth period; 2) the difference of population features (coverage, density, number of blooming plants and biomass) varied between enclosure and grazing conditions; 3) the difference of sexual reproduction quantitive characters was significant; 4) the inflorescence length was positively correlated to the plant height (the ratio between them is the sexual reproduction rate); 5) the size of individual plant was negatively correlated to the density.
