Abstract: By analyzing the historical data of Rhododendron moulmainense community of Xiaowutong Mountain in Shenzhen Wutong Mountain National Park,the authors discover signs of Rhododendron moulmainense population's decay. With the research results of Rhododendron communities in some other scenic spots,the authors consider that this phenomenon is universal in some respects,and suggest that Rhododendron populations of such community should be managed in a classified way and,nurtured moderately and some study be done regularly in the same places.

Key words: Shenzhen Xiaowutong Mountain, Rhododendron moulmainense, population, nurturance
