对不同放牧强度下矮嵩草无性系分株种群地上生物量的研究表明，随放牧强度增加，分株地上生物量、营养体和繁殖体生物量均随之增加。在放牧的各处理间，营养体和繁殖体地上生物量的分配比例无显著差异，与不放牧的对照相比。放牧改变了矮嵩草分株地上生物量的结构，营养体部分生物量的分配比例显著下降，繁殖体部分生物量的分配比例显著提高。每分蘖占分株总生物量的比例随时间和放牧强度的增加而减少。 The study on the aboveground biomass of Kobresia humilis clonal plant populations under different grazing intensities showed that with the increase of grazing intensity, the aboveground biomass, vegetative organs and propagule biomass increased. There was no significant difference in the distribution of above-ground biomass between vegetative and propagules among the grazing treatments, as compared to the non-grazing controls. Grazing changed the structure of aboveground biomass of Kobresia humilis ramets, the proportion of biomass distribution in vegetative parts decreased significantly, and the proportion of some biomass in propagule increased significantly. The proportion of total tillers per stalk decreased with the increase of time and grazing intensity.
