| 摘 要： | 采用通径系数分析和相关分析的方法,随着植物的生长期的推移,分析了生长在松嫩盐碱草地上的星星草种群地上生物量变化和土壤生态因子变化之间的关系。星星草种群包括自然繁育的和人工繁殖１年、２年和３年的。结果表明,二者之间无明显的因果关系。

| Abstract: | By using PCA and correlation analysis methods,the relationship between the changes of aboveground biomass of Puccinellia tenuiflora population growing on the saline and alkaline grassland in Song-Nen and the changes of soil ecofactors was analysed with the passage of growing period of the plant.The Puccinellia tenuiflora populations include both the naturally and the artificially planted for 1,2 and 3 years.The results showed that there is no obvious causal relation between them. |
