摘　　要：探讨了汾河流域临汾段优势种群的生态位特征.结果表明,风花菜、芦苇、藜、齿果酸模的生态位宽度较大,对环境的适应能力较强.芦苇与黄菖蒲、齿果酸模,荠菜与齿果酸模,风花菜与藜之间的生态位重叠值都较高,说明几种植物对资源的利用情况很相似,对资源具有一定的竞争性.The niche characteristics of the dominant populations are explored in Linfen region of Fenhe val- ley. The result show that the niche breath of the species, such as rippa globosa, phragmites australis, chenopodi- urn album and rumex dentatus, is relatively large, and the ability to adapt to environment is stronger. The niche overlap between phragmites australis with iris pseudacorus, rurnex dentatus, and capsella bursa-pastoris with rumex dentatus, rorippa globosa with chenopodium album, is relatively larger, which indicates that the use of natural re- sources of these plants is very similar, and has a certain competition among these plants.
