摘要: 以109个样方调查数据为基础,采用丰富度指数、物种多样性指数和均匀度指数对山西桑干河流域湿地植物群落的物种多样性进行了研究,并用方差分析和多重比较的方法研究了各群落之间多样性指数的差异程度。研究结果表明:各植被类型的物种多样性指数大小排列依次为:柽柳—委陵菜群落>柽柳+沙棘—鹅观草群落>柽柳—鹅绒委陵菜群落>柽柳—芦苇群落>芦苇+水蓼+莎草群落>芦苇+苔草群落>百里香+铁杆蒿群落>香蒲+水蓼群落>水葱+轮藻+眼子菜群落>藨草+莎草+泽泻群落>水葱+藨草+芦苇群落>狐尾藻+香蒲群落>慈姑+芦苇群落>水蓼+慈姑群落>水莎草+水稗群落。对12种多样性指数进行比较后发现,R0、H′和E4优于其他指数。

Abstract: Based on the 109 plots dataset from the field, the species diversity of wetland vegetation of Sanggan River watershed, Shanxi was studied by using richness indices,species diversity indices and evenness indices, respectively. The different significant among these indices for all communities were studied by analysis of variance and Duncan multiple range test, respectively. The results indicated that: The sequence of the species diversity indices was as follows: Ass. Tamarix chinensisPotentilla chinensis>Ass. Tamarix chinensis+Hippophae rhamnoidesRoegneria kamoji>Ass. Tamarix chinensisPotentilla anserina>Ass. Tamarix chinensisPhragmites communis>Ass. Phragmites communis+Polygonum hydropiper+Cyperus glomeratus>Ass. Phragmites acommunis+Carex dispalata>Ass. Thymus mongolicus+Artemisia gmelinii>Ass. Typha orientalis+Polygonum hydropiper>Ass. Scirpus validus+Chara sp.+ Potamogeton distinctus>Ass. Scripus triqueter+Cyperus glomeratus+Alisma orientale>Ass. Scirpus validus+Scirpus triqueter+Phragmites communis> Ass. Myriophyllum spicatum+typha orientalis>Ass. Sagittaria sinensis+Phragmites communis>Ass. Polygonum hydropiper+Sagittaria trifolia>Ass. Juncellus serotinus+Echinochloa phyllopogon. R0, H′and E4 were better than the others by using analysis of variance and Duncan multiple range test, respectively.
