本文对不同程度盐碱生境条件下星星草的生物量，优势度及生理指标进行系统地分析研究。结果表明：星星草的生态分布幅度较窄，但对盐碱生境具有较强的适应能力，在pH值为9．80～10．7，电导率为0.60～0．94ms／cm的土壤都能正常生长。通过其体内积累脯氨酸和无机离子进行渗透调节，以适应盐碱生境条件的变化。
In this paper, we systematically analyzed the biomass, dominance and physiological indexes of P. sibirica under different saline-alkali habitat conditions. The results showed that: Asterispensis sp. Had a narrower ecological distribution, but its ability to adapt to saline-alkali habitat. Soil with pH value of 9.80 ~ 10.7 and conductivity of 0.60 ~ 0.94ms / cm Grow normally. Through its accumulation of proline and inorganic ions osmotic adjustment to adapt to changes in saline-alkali habitat conditions.
