土沉香(瑞香科)的地理分布研究

通过查阅文献资料、标本馆的标本信息以及实地调查对土沉香的地理分布状况进行了分析。结果表明,在我国土沉香主要分布于广东、广西、海南、云南、香港及澳门等地。此外,在台湾、福建和四川金沙江干热河谷等地区也有部分的人工栽培。目前导致土沉香濒危的主要原因在于长期以来人们对野生大树的掠夺性采伐,导致土沉香母树的不断减少,从而使其种群更新难以顺利地进行。因此,要对土沉香的资源状况进行研究,为土沉香的可持续开发利用提供科学依据。

Distribution of Aquilaria sinensis (Thymelaeaceae)

Absract According to the literature retrieval,the specimens and field investigation,the distribution of Aquilaria sinensis(Lour.) Spreng.was analyzed.The results showed that A.sinensis was mainly distributed in Guangdong,Guangxi,Hainan,Yunnan,Hong Kong and Macao.Moreover,it was also cultivated in Taiwan,Fujian and the dry-hot valley in Jinsha River of Sichuan Province.But due to the long-term predatory extraction,the A.sinensis is in the danger of extinction,its seed trees are disappearing,which makes it even harder to update the populations.Thus,the investigation of A.sinensis resources can provide scientific basis for its sustainable development and utilization.
