摘要
2018年5、6月份对西沙群岛的永兴岛、石岛、赵述岛、西沙洲、南沙洲、中沙洲、北沙洲、北岛、中岛和南岛共10个岛屿的植物资源进行了野外考察、标本采集、鉴定以及文献查阅,共记录西沙群岛维管植物90科406种,确定西沙群岛未记录野生维管植物52种,新归化植物10种,新增栽培植物87种,隶属于59科130属,凭证标本保存于中国热带农业科学院植物标本室ATCH。西沙群岛原记录维管植物398种,在此次调查的基础上,结合相关文献资料及植物标本进行统计,西沙群岛维管植物共计101科352属543种,其中野生植物292种,栽培植物251种。此研究为西沙群岛植物资源提供了重要信息。
The plant resources from ten islands of Xisha Islands(including Woody Island, Rocky Island, Tree Island,West Sand, South Sand, Middle Sand, North Sand, North Island, Middle Island and South Island) were surveyed in May and June in 2018. Through field survey, specimen collection and identification and literature consultion, a total of 406 vascular plants belonging to 90 families of Xisha Islands were recorded. 52 wild vascular plants, 10 newly naturalized plants and 87 cultivated plants belonging to 130 genera in 59 families were unrecorded. The voucher specimens are deposited in the herbarium of Chinese academy of Tropical Agricultural Sciences(ATCH). Before this investigation, 398 vascular plants were recorded in Xisha Islands. On the basis of this investigation, in combination with related literature and plant specimen statistics, there are 543 vascular plants belonging to 352 genera and 101 families on Xisha Islands.Among them, there are 292 wild plants and 251 cultivated plants. This study would provide important information for the plant resources of Xisha Islands.
