摘要
目的:探究陕西秦巴山区药用观赏植物资源,为该区域生物多样性保护规划和科学管理提供有效途径。方法:通过文献检索和在线数据库,对陕西秦巴山区45个县(区)的药用观赏植物进行了编目和分布统计,并对其科属种组成、药用部位、观赏特性、园林用途、受威胁状况、多样性分布格局及保护空缺情况进行分析。结果:140科,500属,906种,多为草本植物;从药用部位上看,全草(株)类药用植物最多;从观赏特性来看,观花类植物最多;从园林用途来看,地被类植物最多;基于县域尺度的物种多样性水平分布格局呈现出从东北向西南递增的变化趋势,太白县和眉县是分布热点县,西部和东南部药用观赏植物大多处于保护空缺状态;在垂直分布上,物种丰富度呈现出随海拔的升高先上升后下降的单峰格局。结论:本研究结果可为陕西秦巴山区药用观赏植物资源的持续开发利用,以及未来自然保护区的建立提供科学依据。
Objective:To explore the resources of medicinal ornamental plants in Qinling-bashan Mountains area of Shaanxi Province,and to provide an effective way for biodiversity conservation planning and scientific management in the region.Methods:The medicinal ornamental plants in 45 counties(districts)in Qinling-bashan Mountains area of Shaanxi Province were cataloged and distributed through literature search and online database.And their family and genus composition,medicinal parts,ornamental characteristics,garden use,threatened status,diversity distribution pattern and conservation vacancies were analyzed.Results:140 families,500 genera,and 906 species were mostly herbaceous plants.From the viewpoint of medicinal parts,the most medicinal plants were whole grasses.From the viewpoint of ornamental characteristics,the most plants were flower-viewing plants.From the viewpoint of garden use,the most plants were groundcovers.Based on the distribution pattern of the diversity level of the species at the county scale,it showed a trend of increasing from the northeast to the southwest.The hotspot counties were Taibai and Meixian counties,and the western and southeastern counties were the hotspot counties.The hotspot counties were Taibai County and Meixian County,and most of the medicinal ornamental plants in the western and southeastern parts of the country were in the state of protection vacancy.In the vertical distribution,the species richness showed a single-peak pattern of increasing and then decreasing with the increase of elevation.Conclusion:The results of this study provided a scientific basis for the sustainable development and utilization of medicinal ornamental plant resources in Qinling-bashan Mountains area of Shaanxi Province,as well as the establishment of nature reserves in the future.
