Higher Ca distributed in bulliformcell than in mesophyll cell and bundle sheath cell of dune reed, higher Mg distributedin mesophyll cell and higher K, Na and Cl distributed in sheath cell HigherNa and Mg distributed in mesophyll than in bulliform cell and bundle sheathcell of light salt meadow reed, and higher K, Ca and Cl distributed in itsbundle sheath cell. Higher Na and Mg distributed in bulliform cell than in mesophyllcell and bundle sheath cell of heavy salt meadow reed, higher K, Ca and Cl distributedin its mesophyll cell. This paper discussed the distribution conditions of theabove five ions in leaf cell of the four reed ecotypes and the meaning ofphysiological adaptation to habitat in detail.

沙丘芦苇的泡状细胞内Ca分布较叶肉细胞和鞘细胞高，叶细胞内Mg分布较高，在鞘细胞内K，Na和Cl布较高；轻度盐化草甸芦苇叶肉细胞内分布了较多的Na和Mg，在鞘细胞内K，Ca和C1分布较叶肉细胞和泡状细胞高；而重度盐化草甸芦苇泡状细胞内分布了较多的Na和Mg，叶肉细胞分布了较多的K，Ca和Cl；详细讨论了以上五种离子在不同生态型芦苇叶片内不同细胞类型的分布状况与环境适应的意义。
