周至国家级自然保护区重点保护野生植物的研究

Researches on the State Key Conservation Plant Species in Zhouzhi National-level Nature Reserve

采用鱼骨式线路调查方法 ,对周至国家级自然保护区的重点保护植物进行调查。结果表明 ,该区分布有 1 0种国家级重点保护植物 ,其中稀有植物 5种 ,濒危植物 2种 ,渐危植物 3种 ,并发现了大面积的独叶草 ( Kingdonia uniflora)及巴山冷杉 ( Abies fargesii)群落。分析了其生存现状、保护价值及生物学生态学特性 。

In this paper, the national conservation plant species were investigated in Zhouzhi National Level Nature Reserve by along fish skeleton routes. The results indicate that 10 species of state key conservation species are distributed in this area, in which, 5 species are rarer plants; 2 are endangered plants; 3 are vulnerable plants. Kingdonia uniflora and Abies fargesii are discovered in large areas. Based on the analysis of their current living conditions, conservation value, biological and ecological characters, relative conservation measures and suggestions are proposed.
