摘要
采用“盐分增量法”测定了松嫩平原大安古河道试验站典型的羊草 星星草 碱地蒲公英群落分布区的植被蒸散量。结果表明 ,盐分增量法是一种测定植被蒸散量的新方法 ,可有效地测定植被蒸散量 ;植被日均蒸发量随植被盖度增加不断减少 ,日均蒸腾量随植被盖度增加逐渐增大 ,由于蒸腾量增加幅度大于同期蒸发量减少幅度 ,植被日均蒸散量随植被盖度增加而增大。
Employing salt increment method,the evaportranspiration quantity of Leymus chinensis-Puccinellia tenuiflora-Tarxacum sinicum community at the Da'an Paleochannel test station in Songnen Plain was measured.The results showed that as a new method,salt increment method could determine the evaportranspiration of the plant community effectively.The daily evaporation decreased with the increasing vegetation coverage,while the daily transpiration increased with the vegetation coverage increase.As the increment of transpiration was more than the decreasingevaporation in the same period,the community evaportranspiration still increased with the increase of vegetation coverage.
