摘 要:通过查阅蜡叶标本并结合野外实地调查,对香港木兰Lirianthe championii野外生存状况和致濒原因进行研究分析。结果表明,野生香港木兰因生存环境恶化,分布海拔呈降低趋势,并趋向水沟旁分布;人为破坏不是香港木兰野生居群衰退的直接原因,其自身生殖能力的衰退和生理生态特性对现存生境的不适应才是导致该种群衰退的直接原因。香港木兰野生种群呈现持续衰退的状况,应归入"易危UV(Vulnerable)"保护级别。Based on herbarium and wild investigation,the wild survival situation and endangered reasons of Lirianthe championii were studied.Results showed that,the distribution altitude of wild L.championii showed a decreasing trend and tended to distribute along ditches because of the deterioration of its living environment.Human damage was not the direct reason of the decline of wild L.championii population.Reproductive ability decline and inability of its physiological and ecological characteristics to the existing habitat was the direct cause.Wild L.championii population had been in a state of continuous decline and should be classified as‘UV(Vulnerable)’protection level.
