分析发现,季节冻土在高寒草甸植被生产力形成过程中有着积极的影响作用,主要表现在:1)季节冻土的存在和维持将给高寒植物生长提供良好的土壤水分,对植物初期营养生长发育有利,可弥补春夏之交时降水不足所引起的干旱胁迫影响;2)季节冻土的长时间维持,有利于植物残体和土壤有机质留存于土壤,并随土壤冻结和融化过程发生迁移,可提高土壤肥力;3)较高的土壤水分有利于土壤胡敏酸的形成,可保证植物生长所需的其它有机元素的供给;4)冻土层所形成较高的土壤水分使土体热容量加大,从而调节因气候异常波动引起的土壤温度变化;5)季节冻土的变化对植物地上年生产量形成有一定的影响作用,表现出从10月或11月开始,土壤冻结速率快,对提高植物地上年生产量有利。
