摘要： 碱茅在退化草原上的生长具有明显的季节变化规律，生物量最大值在8月份(98.4 g／m2)。通径分析表明：土壤水解氮、有效磷，速效钾，pH，含水量和电导率在8种环境因子中对碱茅的生长，无论直接影响，还是间接影响都是很很需要的。
Abstract: In degraded grasslands, the growth of Puccinellia tenuiflora follows a seasonal variation pattern, with a maximum biomass in August (98.4 g/m2). Among the eight environment factors that directly and indirectly affect the growth of Puccinellia tenuiflora, hydrolysable nitrogen, effective phosphorus, quick-acting potassium, pH, water content and electric conductirity are the most important.
