摘　　要：【目的】渠系廊道生境是生物栖息的重要场所,对灌区生物多样性的维持具有重要意义。对都江堰精华灌区渠系廊道自生植物及其在不同生境的构成与多样性特征进行研究,有利于灌区生物多样性保护与渠系廊道景观优化。【方法】在春季对研究区域自生植物进行全面调查,共收集81个样点、167个样方数据,将所在生境划分为6类,进行物种组成分析并比较不同渠系廊道、生境类型的多样性差异。【结果】1)共记录到自生植物79科、180属、257种,优势种以一二年生和多年生草本植物为主;2)优势群丛驳岸生境有15个,岸上生境有24个,可为特定生境提供群落构建参考;3)6类生境在物种、优势种构成及多样性方面均存在差异,尤其是硬质驳岸生境与其他生境差异显著。【结论】渠系廊道不同生境植物构成差异明显。研究结果为都江堰渠系廊道生物多样性保护以及廊道生境优化提供了理论支持,有利于通过科学保护和利用自生植物促进渠系廊道的生态优化。[Objective]The canal system is crucial for altering the hydrological processes in agricultural irrigation areas and serves as a vital ecological network within these areas.The canal corridor habitat,an important habitat for various organisms,plays a significant role in maintaining biodiversity in irrigation areas.The Dujiangyan Essence Irrigation Area,located in the southeast of Dujiangyan City in Chengdu,is an important site for biodiversity conservation and a key component of the regional green space ecological network.Studying the composition and diversity characteristics of spontaneous plants in different habitats within the canal corridor of the Dujiangyan Essence Irrigation Area is beneficial for biodiversity conservation and the optimization of canal corridor landscape.[Methods]This research conducts a comprehensive survey of spontaneous plants in spring,collecting data from 81 sample points and 167 quadrats.Habitats are categorized into six types:semi-natural revetment,hard revetment,wasteland,artificial green space,hard plot and self-use vegetable plot habitats.Community composition analysis is performed using Two-way indicator species analysis(TWINSPAN),and the diversity of spontaneous plants in different canal corridors and different types of habitats is compared by Kruskal-Wallis test.[Results]1)A total of 257 species of spontaneous plants belonging to 180 genera and 79 families,are recorded in the canal corridor of Dujiangyan Essence Irrigation Area.These species encompass 10 life forms,with perennial herbaceous plants being the most abundant,followed by annual and biennial herbaceous plants.In terms of species origin,native spontaneous plants account for 42.02%of the total,representing the largest proportion.The life forms of the dominant species are mainly annual and biennial herbaceous plants and perennial herbaceous plants,and the species origins of the dominant species are mostly native and domestic species.2)15 dominant clusters are identified on revetments and 24 ones on shores.Dominant cluste
