摘　　要：通过对无棣贝沙堤植物多样性的分析发现,样方内共出现物种20余种;同时,贝沙堤向海面和贝壳滩脊、向陆一面分别分布着以芦苇、獐茅、大穗结缕草、二色补血草、砂引草以及以青蒿、蒙古蒿、阿尔泰紫菀为优势种的群落。由于人为影响强度不同,大口河和王子堡地区物种盖度、物种多样性指数存在显著差异,分别处于演替初级和次级阶段。而从贝沙堤向海-滩脊-向陆断面上来看,群落多样性指数不断增加,群落更趋于稳定。This paper discussed the plant diversity in WU DI chenier. Only 20 species were found in the quadrat. Phragmites Australis, Ael uropus liitoralis,Zoysiamacrostaehya, Messersehmidia sibiriea, Limonium bicolor were the main vegetation types in the chenier seaside, but in the ehenier plain , Artemisia annua ,Artemisia mongoliea and Herba Heteropappi Altaici occurred frenquently. Due to the men activity, and with the lower and the latter success progress , there was large difference about the vegetation coverage and plant diversity in Da Kou-he and Wang Zi-pu area. From seaside, shell ridge to landside section, following the improved diversity index, the community became more and more stabller
