| 摘 要： | 在土默川平原3个样地对盐生植物种群分布特征及其土壤盐分的测定表明,耐盐植物空间分布的优势度随土壤盐分含量的增加而增高,且植物体内的离子结构特点与土壤离子结构有关。如果植物体内的K++Na+、Cl-浓度高,植物的耐盐性就较强,如碱蓬、碱地风毛菊、碱蒿等的耐盐碱能力较强。同一种植物的盐分离子含量随土壤盐分离子含量的增加而增大,且植物体内盐分含量变化幅度比土壤盐分含量的变化幅度要大,植物耐盐性越强,植物盐分变幅越大,表明植物能够富集土壤中的相应离子。

| Abstract: | According to the population distribution characteristics of halophytes and soil salinity analysis in the Tumochuan Plain, the dominance of spatial distribution of salt-tolerant plants increased with the increasing soil salinity, and the ionic structure in plants was related to that in soil. The plants like Suaeda glauca Bge., Saussurrea salsa (Pall.) Spreng. and Artemisia anethifolia Web. which had higher concentration of K++ Na+ and Cl- tended to have stronger salt tolerance. The salt content in plants inc... |
