摘要
Abstract
Objective] The aim was to study the habitat and wild population distribution of Loropetalum subcordatum species with extremely small populations on the mountain of Wuguishan in Zhongshan City.[Method] Though field investigation, the distribution of Loropetalum sub-cordatum species on the mountain of Wuguishan in Zhongshan City, Guangdong Province was investigated.[Result] In the horizontal direc-tion, the distribution of Loropetalum subcordatum in Wuguishan was discontinuous, uneven and narrow; There were no seedlings underforest-erea, and the natural regeneration of Loropetalum subcordatum was difficult, indicating that it was a declining population;Part of big trees were growing from the plants which were felling before, the habitat was disturbed seriously by human and the population has been becoming more and more extinction.[ Conclusion] The causes of population decline due to human disturbance as well as the biological and ecological charac-teristics of Loropetalum subcordatum which is urgently required for the conservation and utilization by strengthening in situ conservation , off site conservation, propaganda and education work as well as perfecting of laws and regulations.关键词
