During the process of long-time adaptive evolution, wetland plants adopted a series of special strategies to acclimate to salt stress. The main strategies are: 1 life history adjustment, e. g., to adjust seed germination time, implement seed dormancy and viviparity, and change reproductive manner to escape from direct salt stress, 2 morphological adjustment, e. g., to adjust biomass allocation pattern, age stem, defoliate, and carnify vegetative organs to isolate the redundant Na(superscript +) to the inactive-metabolism shoots or exclude the Na(superscript +)from tissues; 3 anatomic adjustment, e. g., to sink stoma, develop aerenchyma, and thicken cuticle and phellogen to maintain normal photosynthesis and respiration; 4 physiological and biochemical adjustment, e. g., to exclude and excrete salt, compartmentalize ions, adjust osmosis, do selective absorption, regulate hormones, and induce antioxidative enzymes to maintain the osmotic equilibrium and eliminate the active oxygen in cell; and 5 molecular level adjustment, e. g., to start up many salt-induced genes to regulate the metabolic responses to salt stress.

在长期的适应进化过程中，湿地植物形成了多种适应盐胁迫的策略，主要有：1生活史方面，植物可通过种子萌发时间的调整、种子体眠、胎生、繁殖方式的改变等逃避盐度的直接伤害；2形态学方面，植物可通过生物量分配模式的调整、茎的老化、落叶及营养器官的肉质化等将多余的Na隔离到代谢不活跃的茎中或将其排出体外；3解剖学方面，植物可通过气孔下陷、发达的通气组织、增加细胞木栓层、角质层及栅栏组织的厚度等以维持植物正常的光合作用和呼吸作用；4生理生化方面，植物可通过离子区隔化、拒盐、泌盐、选择性吸收、渗透调节、激素调节及抗氧化物酶的诱导等来维持细胞内正常的渗透压，清除胞内活性氧分子；5分子水平方面，植物可通过多种与盐胁迫相关的基因来调控细胞内的多种代谢反应。
