选取１２个样方，调查了高山灌丛生物量和营养元素含量随海拔、坡向和坡度的变化状况。头花杜鹃、高山柳和草本植物分别在海拔３５００ｍ、３６１０ｍ和３６２０ｍ达到其生物量的最大值；高山植物的根／茎比随海拔升高而增大；西坡高山灌丛的生物量大于南坡；坡度对高山灌丛生物量在各器官中的分配影响较大；海拔高度、坡向和坡度对高山植物营养元素含量的影响不明显。
Twelve quadrats were selected to investigate the changes of biomass and nutrient elements in alpine shrubs with altitude, aspect and slope. The flowering rhododendron, alpine willow and herbaceous plants reached their maximum biomass at the altitude of 3500m, 3610m and 3620m, respectively. The root / stem ratio of alpine plants increased with the altitude increasing. The biomass of alpine shrubs on the west slope was higher than that of south Slope. The slope degree has a great influence on the distribution of alpine shrub biomass in various organs. The effects of altitude, slope and slope on the nutrient content of alpine plants are not obvious.
