Changes in inorganic ion accumulation and growth of Leymus chinensis community along the retrogression on the Songnen grassland in northeastern China

摘要：

Songnen grassland is one of the main districts in which Chinese saline‐alkali soil concentrates.L.chinensis community grassland occupies 65％ of total grassland area in the Songnen Plain.The strong rhizomes of L.chinensis adapt to saline‐alkaline and dune conditions.Through Na＋, K＋, Ca2 ＋,Cl‐, NO-3, SO2‐ 4 accumulation and ratio, we tried to find the adaptability of L.chinensis growing naturally along the grassland retrogressive process.
