摘要： 为明确白洋淀芦苇田杂草的发生情况,2008-2009年在白洋淀的6个乡(镇),采用随机取点和倒置"W"取样相结合的方法对白洋淀芦苇田杂草种类及发生情况进行了调查。初步确定白洋淀芦苇田常见杂草29科103种。相对多度在10%以上的有十种杂草,它们是狗尾草、野大豆、大狼把草、葎草、盒子草、牛鞭草、虉草、荠菜、犁头草和水蓼。白洋淀芦苇田杂草群落有以下四个主要特点:不同区域优势杂草种类差异很大;牛鞭草、虉草、萝藦、大刺菜、白茅等多年生杂草种类多;盒子草、葎草、野大豆、萝藦、打碗花等藤本类杂草为害严重;虉草、大狼把草等新的苇田杂草增多并且为害严重。

Abstract: The weed in reed fields from six town of Baiyangdian Lake was investigated by the method of random sampling and inverted W-sampling pattern in 2008－2009. 103 weed species from 29 families were found. Ten weed species were dominant in reed fields based on the analysis of their relative abundance. They are Setaria viridis,Glycine soja,Bidens frondosa,Humulus scandens,Actinastenma lobatum,Hemarthria altissima,Phalaris arundiacea,Capsella bursa-pastoris,Viola japonica,Polygonum hydropiper in which the relative abundance is over 10%. The weeds communities in Reed fields of Baiyangdian Lake have following four characteristics: The dominant weed species were variable in different area; Perennial weed for example H. altissima,P. arundiacea,Metaplexis japonica,Cephalanoplos setosum,Imperata cylindrical were aboundent; The liane weed species such as A. lobatum,H. scandens,G. soja,M. japonica,Calystegia hederacea can cause severe damage to reed; New weed species such as P.arundiacea and B. frondosa occur seriously.
