摘要:

梵净山石斛(Dendrobium fanjingshanense)资源稀缺,具有重要的开发价值。为了更好地保护和利用这一珍贵资源,对浙江九龙山国家级自然保护区内梵净山石斛原生境进行调查,结果表明:1)梵净山石斛主要附生在乔木树种上,分布高度主要集中在15~20 m;其开花率高达64.8%,但结实率极低,且有大小年之分。2)光照的测量结果显示,群落郁闭度约70%左右;温湿度的监测结果显示,5—9月群落内平均温度21.8℃、平均相对湿度98.4%。根据调查资料估算,区内蕴藏量(鲜重)在10 kg左右。

Abstract:

Because of the scarcity of resources,Dendrobium fanjingshanense has important development value.In order to better protect and utilize the precious resources,the habitats of D.fanjingshanense in Jiulong Mountain National Nature Reserve were investigated.The results showed that D.fanjingshanense was mainly attached to arbor tree species,and the height distribution is mainly between 15m and 20m.The flowering rate of D.fanjingshanense is up to 64.8%.However,the rate of seed bearing was very low.The canopy density of the community was about 70%.The average temperature in the community from May to September was 21.8 ℃,and the average relative humidity was 98.4%.According to the survey data,the accumulation amount (fresh weight) in the area is about 10 kg.Finally,the relevant protection countermeasure were proposed.

Key words: Jiulong Mountain National Nature Reserve, Dendrobium fanjingshanense, habitats, investigation, countermeasure
