金佛山自然保护区兰科植物多样性及保护对策研究

Study on the Orchid Diversity and Protective Strategies of Jinfo Mountain Nature Reserve in Chongqing

摘要:

通过对保护区内兰科植物的调查，分析了保护区内兰科植物的物种多样性、垂直分布格局。结果表明，金佛山兰科植物种类丰富，区系成分复杂多样，共有兰科植物48属114种；金佛山兰科植物特有现象明显，中国特有兰科植物47种，3种为金佛山特有；垂直分布格局明显；不同海拔段的兰科植物濒危程度差异较大，低海拔地区物种受威胁程度较低，资源保存状况更好。对造成兰科植物濒危的主要原因进行了分析，并提出了保护对策。

Abstract:

The orchid diversity from Jinfo Mountain Nature Reserve, Chongqing, South China was studied. The results showed that 114 species orchids belonging to 48 genera distributed in Jinfo Mountain Nature Reserve, in which 47 species endemic to China and 3 species endemic to Jinfo Mountain. Vertical distribution pattern of orchid was obvious. The threatened status of orchid was significant different in different altitude. The species at low altitude were less threatened than those at high altitude. Some strategies were proposed for in situ conservation of orchid diversity in Jinfo Mountain Nature Reserve.
