攀西地区毛红椿资源分布现状初步调查

Preliminary investigation on the Distribution of Toona ciliata var. pubescens Resources in Pan Xi Areas

毛红椿是珍稀树种,被列为国家二级保护濒危种,对攀西地区的毛红椿种质资源分布现状进行初步调查,分析其资源分布范围、分布特点及资源存量。结果表明:攀西地区毛红椿资源数量少,呈零星分布,约几十株,主要分布在德昌、盐边、米易,自然更新能力较差,应采取措施进行保护。

Toorta ciliata var. pubescens is an endemic and rare wood species and is listed as endangered species under state protection （category Ⅱ ）. Investigation was made on the distribution of toona ciliata var. pubescens resources in Panxi areas and analysis was made of its resource distribution, distribution characteristics and resource stocks. The results showed that Panxi area had fower toona ciliata var. pubescens resources. And they were scattered with about dozens of strains, and were mainly distributed in Dechang, Yanbian and Miyi. Their natural regeneration ability was poorer, therefore some protection measures should be taken.
