摘要
利用踏查、无人机拍摄、航片识别等方式,对内伶仃岛有害藤本进行全面系统的调查。结果表明,内伶仃岛有典型斑块或斑点状分布的有害藤本共12种,其中外来种4种,本地种8种,分布总面积约为51.9万m2,占全岛陆地面积的11%。岛上本地有害藤本分布总面积占全岛的7.67%,是外来有害藤本的两倍多,且本地木质藤本刺果藤已经取代薇甘菊成为目前内伶仃岛上危害最严重的藤本植物。
Field survey, unmanned aerial vehicle survey and aerial photo analysis were used to check the distribution ofharmful lianas in Neilingding Island. Twelve typical harmfullianas were found during the survey, and four of them wereexotic species, and the other eight were native. Total distributed area of these twelve typical harmful lianas was about51.9 ha, accounted for 11% of this island, and the native lianas' proportion is about 7.67%, more than double size of theexotic four species. Instead of Mikaniamicrantha, Byttneriaaspera became the most harmful liana in this island.
