Abstract Through the investigation of the site conditions of Rhododendron moulmainense in Wanhuaping and Dujuan Valley of Wutong Mountain，the main reasons for the decline of Rhododendron moulmainense were analyzed， including excessive plant nutrient consumption， poor soil water and fertilizer retention capacity， unreasonable community canopy closure， aging of trees， and the influence of climate and human activities. Revitalization measures were proposed from the aspects of water and fertilizer management， canopy closure adjustment， soil improvement， understory regeneration， and flower and fruit picking.
