In different degree of saline and alkali conditions controlled in lab or under field, contents as followed were determined: the absorption, transportation and distribution of major cations Na~+, K~+, Ca~(2+and Mg~(2+) in indicator plant; organic solute, and antioxidase activities, including superoxide dismutase, catalase and peroxidase POD characteristics of individual, population and community of the plant. Responses of the indicator plant to environment from physiological to community aspects were systemically discussed in this document.(1 Vegetional characteristics and edaphic indicators including bare patch index, dry biomass, percent cover by perennial plants, growth indicators of Leymus chinensis, soil organic matter and pH were sensitive to saline-alkali grassland degeneration.
