浙江省余杭区林湿生态系统外来入侵物种现状及防控策略

Research on the Current Situation and Control Strategies of Invasive Alien Species in Forest and Wetland Ecosystem of Yuhang District, Zhejiang Province

摘要: 通过对林湿生态系统中外来入侵物种现状进行全面普查，评估潜在风险，为外来入侵物种防控管理提供科学支撑。结果表明，余杭区共发现13种外来入侵物种，其中陆生植物6种、水生植物6种、无脊椎动物1种。加拿大一枝黄花、福寿螺、大狼杷草和喜旱莲子草危害较大，风险评估为中风险。基于普查结果提出加强林湿资源保护、加强重点区域和重点物种监测防控、开展宣传教育等策略，为保护区域生态安全和生物安全提供借鉴与参考。

Abstract: Based on a grasp of the current state of forest and wetland resources in Yuhang District, we conducted a census of invasive alien species in the forests and wetlands ecosystems and assessed their potential risks. Results show that a total of 13 invasive alien species were discovered in Yuhang District, including 6 terrestrial plants, 6 aquatic plants, and 1 invertebrate. Among these species, the Canada goldenrod (Solidago canadensis L.), Fuchsia snail, Great wolf loosestrife, and Pleasant drought lotus grass have an intermediate risk rating, indicating greater danger. Based on the results, we propose a series of control strategies, including strengthening the protection of forest and wetland resources and enhancing the prevention and control of key areas and key species. These strategies will help protect the ecological and biological security of Yuhang District.
