摘　　要：基于山西浊漳河干流湿地149个样方数据,采用Spearman秩相关系数检验法分析了浊漳河湿地27个优势种种间关系。Spearman秩相关系数检验表明,优势种组成的351个种对中,负相关占绝对优势(242对),正负相关比为3∶7,呈显著和极显著相关的种对仅占16.8%。根据优势种间关系结合物种对不同生境(主要是水分条件)的适应情况,山西浊漳河流域草本植物划分为中生植物、湿中生植物、湿生植物和水生植物4个功能群。各植物功能群沿水分梯度依次出现在浊漳河河漫滩地势较高处、河漫滩地势较低处、季节性河漫滩积水区、河道和沼泽。Based on the datasets of 149 plots from the wetland herb communities in Zhuozhang River watershed, Shanxi, the relationships of 27 dominant species were analyzed by Spearman rank correlation coefficient test. The results showed among 351 pair-species, the pair-species of negative association （ 242 pair-species） were dominant, and the ratio of positive to negative asso- ciation was 3：7. The proportion of species-pairs having a significant or highly significant correla- tion was 16.8%. According to the association of dominant species and the adaptability of species to habitats （ mainly moisture conditions）, the dominant species were divided into four plant func- tional groups （PFGs） ： mesophyte, mesohydrophyte, hygrophyte and hydrophilous. The PFGs along the moisture gradient were distributed in the top of flooding plain, the lower of flooding plain, the seasonal watering area of flooding plain, and the river and marsh of Zhuozhang River, respectively.
