| 摘 要： | 目的 外来入侵植物对其入侵地的生物多样性和生态安全造成了严重影响。本研究目的是为掌握浙江普陀山外来入侵植物的危害现状，评估其主要危害和防控区域。 方法 对岛屿不同区域进行样方调查，通过分布区域、优势度、浙江省外来植物入侵等级进行加权统计评分的方法，评定各外来入侵植物的危害程度、入侵等级，确定普陀山外来入侵植物的重点危害区域和防控区域。 结果 普陀山外来入侵植物全为草本植物，共计47种，分属于21科36属。来自美洲的入侵植物有38种，占总种数的80.85%。中度危害与严重危害的种类共23种；入侵等级为1级与2级的种类共22种。丘陵山地、郊野荒地以及海岸滩涂是普陀山外来入侵植物的重点危害和防控区域。 结论 普陀山的外来入侵植物危害现状较为严重，建议加大宣传力度，开展海岛联动防控，加强外来物品入岛检验检疫工作，做好外来植物应用前的入侵危害风险评估与防控工作预案。表1参31

| Abstract: | Objective Alien invasive plants have huge negative impacts on the biodiversity and ecological security of native ecosystems. This research aims to understand the situation of invasive plants in Putuoshan Island, Zhejiang Province. Method Sample surveys were conducted in different areas of Putuoshan Island. According to the weighted statistics of distribution area, coverage and the Zhejiang invasion level, the harm degree and invasion grade of various invasive plants were assessed, and the key harm areas, and prevention and control areas of invasive plants in Putuoshan Island were determined. Result There were totally 47 alien invasive species of plants, belonging to 36 genera of 21 families, and all of them being herbaceous. Moreover, out of total observed invasive species, 80.85% (38 species) were found to be native of America. 23 species of plants were in moderate or serious harm, and 22 species could be seen in plants belonging to class Ⅰ and class Ⅱ degree. Conclusion Hilly mountains, desolated land and coastal wetlands are important ecological regions of Putuoshan Island where control of alien invasive species is much needed. Since the present situation of invasive plants in Putuoshan Island is serious, it is necessary to increase publicity about bad impacts of invasive species, carry out joint programs to control their spreading, and strengthen the quarantine inspection of alien plants into the island. Additionally, adequate risk assessment of non-native plants should be carried out before their intentional application to prevent and control any invasive hazards in future. Ch, 1 tab. 31 ref.] |
