宜昌市楠木类树种资源及保护

Resources and Protection of Nanmu Tree Species in Yichang

2015～2017年对宜昌楠木类树种资源进行调查,调查结果表明:宜昌习惯将樟科中的楠属、润楠属树种及琼楠属、山胡椒属的部分树种统称为"楠木",已发现17种,按起源划分乡土6种,引进11种;按属划分楠属6种,润楠属9种,琼楠属1种,山胡椒属1种。由于人为砍伐和生境破坏,加上自身繁殖率低的原因,楠木类树种自然资源近于枯竭,部分楠木类树种引进栽培获得成功,保护和发展工作有待进一步加强。

From 2015 to 2017, a survey was conducted on the resources of Nanmu tree species in Yichang. The results of the survey showed that Yichang used to collectively refer to the genus Phoebe in the family Polygonaceae, the genus Machilus, and some tree species of the genus Beilschmiedia and the genus Lindera as “Nanmu”. 17 species have been found. According to the origin of 6 kinds of local, introduced 11 kinds;According to the genus, there are 6 species of Phoebe, 9 species of Machilus, 1 species of Beilschmiedia, and 1 species of Lindera. Due to human felling and habitat destruction, coupled with the low reproduction rate, the natural resources of Nanmu tree species are nearly exhausted, and some Nanmu tree species have been successfully introduced and cultivated, and protection and development work need to be further strengthened.
