摘要：广西雅长林区野生兰科植物资源丰富,约有52属156种,其中雅长保护区几乎每座山头都有兰科植物的分布,但其种类与居群基株数量等分布不均匀,且不连续,呈现出破碎化现象,其中面积较大的局部密集分布区有16处。文中根据野生兰科植物的资源现状及生物生态学特性,针对目前兰科植物保育存在的问题,分析人畜干扰及自然条件变化等不利因素,从兰科植物维持机制角度出发,提出雅长野生兰科植物的保护应以就地保护为主、迁地保育为辅的保育措施与策略:保护区应加快建设的步伐,构建野生兰科植物种质资源基因库,同时对密集分布区在人畜干扰大的区域,优先拉设铁丝网围护,并派专人巡护,重点保护,确保野生兰科植物及基因库安全。
The Yachang forest region is rich in wild orchid diversity,with 156 orchid species belonging to 52 genera distributed in the hills throughout the Yachang Orchid Nature Reserve.The orchids’ distribution in the Yachang region is,however,uneven and naturally or unnaturally fragmented.In particular,there are sixteen distribution hotspots with large concentrations of orchid species and populations within the region.The continuing existence of these rich wild orchid resources are threatened by disturbance from human activities,livestock grazing,and other fast-changing environmental conditions within the Yachang region.We recommend that the conservation strategies of the wild orchids in Yachang should include primarily of in-situ conservation measures,supplemented by ex-situ conservation.Yachang Orchid Nature Reserve should complete and improve its protection facilities as soon as possible,including the completion of a wild orchid germplasm bank,construction of fences around orchid-rich areas that are subject to heavy herbivory from livestock,and intensification of foot-patrols in these areas.
