河南太行山区野生珍稀濒危植物资源研究初报

Studies on Endangered and Valuable Wild Plant Species in Henan Taihang Mountain

河南太行山区保存有许多珍稀濒危植物资源。为进一步加强对这些资源的保护、研究和利用,笔者以河南辉县、林县和济源太行山自然保护区为重点,通过对51种野生珍稀濒危植物资源的地理分布、生态环境等的调查发现,许多珍稀濒危植物数量偏少,散生或零星分布,位于山谷沟壑等人迹罕至位置;而连香树等少数资源因得到人为繁殖保护,数量扩大。野生珍稀植物的濒危状态除受其自身生物学特性的内在制约和生态环境的外在影响外,人类的合理或不合理开发利用已成为这些资源濒危状况的重要影响因子。

The Henan Taihang Mountain area preservation has many rare and precious endangered plant species. To further strengthening these resources protection and exploitation, the author investigated the geographic distribution, the ecological environment of 51 species of wild rare and precious endangered plant, with the Taihang Mr. nature protection area in Henan Hui County, Lin County and the Jiyuan city as the key point. The investigation discovered that many rare and precious endangered plants distributed dispersing and located at unvisited mountain valley positions, their quantity are few. Because of artificial reproduction and protection, the quantity of minority resources such as Cercidphyllum japonicum, were increased. The investigation also found these plants endangerment were caused by human reasonable or unreasonable exploitation, besides the species own biology characteristic and its ecological environment.
