摘　　要：以双台子河口芦苇湿地为研究对象,对2009年10月野外调查所获取的土壤、植物样品进行室内分析,研究盐分离子和植被群落退化演替的关系。结果表明:根据芦苇生物量、覆盖度、株高3项生长指标变化,研究区芦苇群落退化演替的顺序为芦苇—芦苇/补血草—芦苇/碱蒿—芦苇/碱蓬—獐茅/翅碱蓬—翅碱蓬。随着退化演替的进行,翅碱蓬群落的各盐分离子含量显著高于其他五种植物群落的含量。电导率与芦苇生物量、株高呈显著负相关,与土壤易溶盐离子(除CO2-3)呈极显著正相关(P<0.01)。说明各盐分离子通过影响电导率而间接抑制植物生长,电导率与pH呈极显著正相关(P<0.01),说明试验区土壤盐化的同时伴随着碱化。Take the Shuangtaizi River estuary wetland as the study object, soil, plant samples obtained in 2009 October field survey were indoor analyzed in research of relations of salt ions and vegetation community degeneration. The results show that： according to growth index change of the reed biomass, coverage, and plant height, degradation succession order of reed community is Reed-Reed / Limonium- Reed / Artemisia anethifolia- Reed / Suaeda salsa- Aeluropus littoralis / Suaeda salsa-Suaeda salsa. With the degradation succession, the content of the salt ion of Suaeda salsa community was significantly higher than that of other five kinds of plant community. Conductivity was negatively correlated with reed biomass, plant height, and were positively correlated with （P〈0. 01） soil soluble salt ions （except CO3^2-）. The experimental results illustrate the effect of salt ions on plant growth through Electrical conductivity. The electrical conductivity is significantly positive correlation with pH （P〈0.01）, which shows that test area occurs soil salinization accompanied by alkalinization.
