2012年7～9月在云南省老君山自然保护区6个不同海拔梯度带各设置3个5 m ×5 m的典型样地，对不同海拔梯度带腺房杜鹃灌丛的群落特征及其生物量分配特征进行研究。结果表明，（1）老君山腺房杜鹃灌丛群落有维管植物58种，隶属于28科49属，其中蕨类植物4科5属5种，被子植物23科43属52种，裸子植物1科1属1种。58种植物中，草本植物种类最多，有20科30属36种，占总数的62.06％，木本植物9科16属22种，占总数的36.94％。（2）海拔对腺房杜鹃生物量的分配具有一定的影响，大致表现为随着海拔升高生物量呈下降趋势（2500～3260 m）。（3）老君山腺房杜鹃根、茎、叶各部分的生物量的分配规律为茎＞根＞叶，植物各个器官生物量分配与海拔没有显著关系。

Using Rhododendron adenogynum shrub in Laojunshan Mountain as target species, 6 plots were set up along 6 different altitudinal gradient.Each plot was made up of three 5 m ×5 m small plots.Between July and September 2012 , data were collected regarding the change in biomass production and community structure of Rh.adenogynum shrub along different altitudinal gradient.The results showed that: (1) there were 58 species of vascular plants in the communities of R.adenogynum , belonging to 28 families and 49 genera.This was com-prised of ferns (4 families, 5 genera and 5 species), angiosperm (23 families, 43 genera and 52 species) and gymnosperms (1 family, 1 genus and 1 species) .In the community, there were 58 kinds of plants.Herbaceous plants were the most dominant with 20 families, 30 genera and 36 species.This accounted for 62.06%of the to-tal.Woody plants (9 families, 16 genera and 22 species) accounted for 36.94%of the total.(2) The altitude had certain influence on the biomass distribution.The biomass of R.adenogynum ( within the range of 2 500 ~3 260 m) decreased with increase in altitude.(3) The biomass levels of R.adenogynum were in the order of stem>root>leaf.There had no obvious relationships between the biomass distribution in the stem, root and leaf and the altitude.
