摘要
通过查阅文献资料,结合实地走访和踏查,对广西河池市野生兰科(Orchidaceae)植物资源的分布与生境进行调查。结果表明,广西河池市的野生兰科植物共有61属184种,种类丰富,生活型全面,主要以地生和附生为主;地生兰科植物33属90种,附生兰科植物25属83种,腐生兰科植物4属4种,半附生兰科植物3属7种。罗城县野生兰科植物有104种,占河池市野生兰科植物资源总数的56.52%;环江县有131种,野生兰科植物分布最多,占总数的71.20%;天峨县86种,占46.74%。以上3县的兰科植物种数明显高于其他县(区),资源分布不均。河池市野生兰科植物区系成分中,与热带亚洲分布有关的植物占绝对优势;北温带区系和东亚区系的影响较小。河池市的野生兰科植物种类虽然丰富,但仍需加强兰科植物的收集保存、保护和资源利用。
Based on literature references,investigation and reconnaissance,distribution and habitat of wild Or⁃chidaceae plant resources in Hechi of Guangxi were investigated.Results showed that there were 61 genera and 184 species of wild Orchidaceae plants in Hechi of Guangxi including all kinds of living types,which were mainly terrestrial and epiphytic.There were 33 genera and 90 species of terrestrial plants,25 genera and 83 species of epiphytic plants,4 genera and 4 species of saprophytic plants,and 3 genera and 7 species of hemiepiphyte plants.There are 104 species of wild Orchidaceae plants in Luocheng county,accounting for 56.52%of the total resources in Hechi.There were 131 species in Huanjiang county with the maximum distribution,accounting for 71.20%of the total.There were 86 species in Tian'e county,accounting for 46.74%.The distribution of Orchidaceae plant species in the three areas was significantly higher than other counties.In flora of Orchidaceae plants,tropical Asia distribution took absolute advantage.North temperate and East Asian flora had slight influence.Although species of wild Orchidaceae plants in Hechi were abundant,collection,conservation,protection and utilization of Orchidaceae plants should be strengthened.
