摘要

【目的】 植被是湖滨带生态系统的重要组成部分,全面分析湖滨带植物群落组成和多样性特征,为评估湖滨带的健康状况及其生态服务功能提供参考依据。【方法】采用样线结合样方环绕太湖湖滨带进行系统性的野外实地调查,分析植物群落的物种组成和多样性。【结果】①太湖湖滨带共记录植物76科179属226种,主要为湿生和水生的草本植物,其中外来入侵植物种类多、分布广;②依生境条件形成了具有地域特征的不同植物群落,所有群落均至少包含1种外来入侵植物;③重要值居首的外来入侵植物重要值与群落多样性指数呈负相关趋势。【结论】太湖湖滨带生态系统中外来植物入侵现象严重,不利于区域生物多样性稳定的维持,需要强化监控管理。

Abstract

【Objective】 Vegetation is a vital component of the lake shore zone ecosystems. A comprehensive analysis of plant community composition and diversity characteristics is essential for evaluating the ecological health and service functions of the lake shore zone of Taihu Lake. 【Method】We systematically investigated the plant community around the lake shore zone of Taihu Lake using a transect-quadrat survey method to analyze the species composition and diversity. 【Result】(1) The lake shore zone harbored 226 plant species from 179 genera and 76 families, predominantly wetland and aquatic herbaceous plants. Alien invasive plants were numerous and widely distributed. (2) Distinct, regionally characteristic plant communities formed based on habitat conditions, each containing at least one alien invasive species. (3) The important value of the dominant alien invasive species (ranked by the highest important value, IV) exhibited a negative correlation with the plant community’s diversity index. 【Conclusion】Alien plant invasion poses a serious threat to the lake shore ecosystem of Taihu Lake, undermining biodiversity stability. Enhanced monitoring and management are urgently required.
