摘　　要：为洞庭湖菱属植物种质资源的保护和利用提供基础资料,对洞庭湖湿地菱属植物种质资源的种类分布、形态特征、伴生植物等进行调查。结果表明,洞庭湖共有菱属植物7种:分别是乌菱(Trapa bicornis)、四角菱(T.bicornis var.quadrispinosa)、红菱(T.bicornu)、野菱(T.incisa)、菱角(T.japonica)、冠菱(T.litwinowii)和细果野菱(T.maximowiczii),占中国菱属植物种类的26.9%。乌菱、红菱和菱角为栽培种,其他为野生种。乌菱、红菱、菱角在洞庭湖湿地广泛分布,属调查样方中优势种群。在洞庭湖菱属植物种质资源分布中伴生植物仅有15种,且大部分伴生植物的覆盖度和密度均较低。The species distribution,morphological characters and associated plants of Trapain the Dongting Lake wetland were investigated to provide basic data for preservation and utilization of germplasm resources of Trapa.The results showed that there were seven species of Trapa plants（T.bicornis,T.bicornis var.quadrispinosa,T.bicornu,T.incise,T.japonica,T.litwinowii,T.aximowiczii）,which accounted for 26.9% of the species of Trapaplants in China.And among these species,T.bicornis,T.bicornuand T.japonicaare cultivated species,the others are wild species.They are wildly distributed in the region and become dominant plant species in the investigation plots.Only 15 species associated plants of Trapa were found,and most of them,the density and coverage are low.
