摘要
通过枯草季草地干枯牧草量与土壤含水量的相关分析，发现二者之间存在显著正相关关系，说明草地枯草被可有效保持土壤水分。本文还讨论了这一现象的原因，进而阐明枯草被对草地的生态学效应及开展枯草季草地生态学研究的必要性。
y making the correlationship analysis between the soil moisture and the
weight of dry grass on unit area of grasslaiid in spring,we found that there is a remarkable
positive relationship between the soil moisttire and the weight of dry grass on unit area of
grass-land,and explained the cause of it.Moreover base on the conclusion,we had discussed
the necessarity of the study on grassland ecology in the seasons that grass are not grow-ing.
We conside the study of grassland ecology in these season is a very important part of the
grassland ecology,it can not be neglected.
