为了明确河北省沧州地区棉田杂草的群落组成和结构，采用倒置“W”形取样法对河北省沧州地区5个植棉县（市）的50块棉田杂草进行了调查，结果显示：河北省沧州地区棉田杂草有16科39种，其中牛筋草、铁苋菜、马齿苋、马唐是河北省沧州地区棉田的优势杂草；黄骅市、海兴县棉田杂草群落的多样性指数和均匀度指数最大，河间市棉田杂草的优势度指数最大，优势杂草种比较突出。通过聚类分析可知，河北省沧州地区棉田杂草群落可以分为2组：黄骅市、海兴县的棉田杂草群落，其中的喜湿杂草较多；吴桥县、东光县、河间市的棉田杂草群落，其中喜旱性杂草较多。

To understand the composition and structure of weed communities in cotton fields of Cangzhou area in Hebei Province,the weeds in 50 cotton fields of five cotton growing counties (cities) were surveyed by sampling them in a “W”pattern.Weeds in the cotton fields belonged to 16 families and 39 species,among them Eleusine indica ( L.) Gaertn., Acalypha australis L.,Portulaca oleracea L.,and Digitaria sanguinalis (L.) Scop.were dominant.The Shannon-Wie-ner diversity index and Pielou evenness index for cotton -field weeds in Huanghua City and Haixing County were the highest ,the highest Simpson dominance index for cotton fields was in Hejian City ,and the dominant weed species was ob-vious.Through hierarchical cluster analysis ,we can divide the weed communities in the corn fields of Cangzhou area in Hebei Province into two groups:weed communities of corn fields in Huanghua City and Haixing County ,where there are a-bundant hygrophilous weed species;Wuqiao County ,Dongguang County and Hejian City ,where there are many drought tol-erant weed species .
