太行山中段资源树种暖木的濒危状况研究

Research on Endangered Situation of Resources Species Meliosma veitchiorum in the Middle Segment of Taihang Mountain

为摸清河南太行山中段珍稀资源植物暖木的生存现状,采用植物群落野外调研法、实地访问法和室内整理分析法,调查了太行山中段暖木的分布、生态学特征和濒危现状。结果表明:暖木分布在太行山区海拔1 000 m以上的山谷杂木林中,居群数量和居群大小均很小,更新能力及自然繁殖能力差,资源生存现状非常严酷,面临濒危境地,需制定合理的开发利用和保护措施。

In order to find out existence situation of rare species-Meliosrna veitchiorum in the middle segment of Taihang Mountain, using plant communities of field investigation, field access method and interior finishing analysis, the author basically identified the distribution of Meliosrna veitchiorum, ecological characteristics and endangered situation in the middle segment of Taihang Mountain. The results showed that Meliosrna veitchiorum distributed in the valley of spinney above the altitude of 1000 meters in the Taihang Mountain area, its population numbers and population size were both very small and it had poor renewal and natural reproduction, so the species were facing an endangered situation and a rigorous existence situation to survive, it needed to develop a reasonable exploitation and protective measures.
