摘要：潮沟在黄河三角洲广泛存在,且分布有多种独特的湿地植被类型。通过设置有代表性的28个样地,获取了植被种类、多度和土壤环境因子数据;并运用双指示物种(TWINSPAN),对黄河三角洲潮沟分布区植被进行了群落类型划分,得出研究区共有7种类型植物群落;同时利用典范对应分析(CCA)阐明了这些植被群落空间分布与土壤环境因子之间的关系,其分析结果显示构成黄河三角洲土壤盐分的主要是Cl-和Na+,距离海洋的远近和土壤含水量共同影响土壤含盐量,盐地碱蓬和中华柽柳分布主要取决于土壤含盐量、Na+含量及距离海洋距离,而各种植被类型的分布与土壤全磷(TP)、全氮(TN)、有机质、Ca2+及Mg2+含量存在一定的关系。
The tidal creeks are widely distributed in the Yellow River Delta,accompanying with many distinctive types of vegetations.We set 28 sampling sites in the study area and collected the data of vegetations and soil environmental factors.By TWINSPAN and canonical correspondence analysis（CCA）,we analyzed the relationship between the spatial distribution of vegetations and soil environmental factors in the tidal creek areas in the Yellow River Delta;and found that there had 7 types of vegetation communities in the study area.The result indicated that（1） the soil salinity was mainly in the form of Cl-and Na＋;（2） the distance from the sea and the water content in the soil both influenced the amount of the soil salinity;（3） the distribution of Suaeda salsa and Tamarix chinensis were mainly affected by the soil salinity,the content of Na＋ and the distance from the sea,the distribution of Limonium bicolor,Apocynum venetum,Suaeda glauca and Phragmites australis were related with total phosphorus（TP）,total nitrogen（TN）,organic matters,Ca2＋ and Mg2＋ and other types of vegetations were mainly distributed in the areas far away from the sea.
