| 摘 要： | 重叠植被非生育期生态需水量是霜期、持续冰冻期地表有效自由水蒸发量,它维系越冬生境。基于2005~2006年对黄柳-扁蓄豆构成的重叠植被生境中气象因子及生理因子野外观测试验数据,用单、双作物系数法计算了重叠植被2个不同水文年生态需水量。这个基础数据对决策重叠植被建设规模、对区域需水预测模提供了基础数据。

| Abstract: | Ecological water requirement of the overlapping vegetation consist of water requirements in growing season and non-growing season.Ecological water requirement in growing season was composed by the transpiration which is used for keeping life and by the evaporation which are important component of water balance in the root zoon of the ecological niche.The transpiration of the overlapping vegetation can be called as the life water requirement and the evaporation of the soil under overlapping vegetation can be... |
