摘要/Abstract

摘要： The water-heat transfer process between land and atmosphere in Haibei alpine meadow area has been systematically observed.A multi-layer coupling model for land-atmosphere interaction was presented with special attention paid to the moisture transfer in leaf stomata under unsaturated condition.A profound investigation on the physical process of turbulent transfer inside the vegetation has been performed with a revised formula of water absorption for root system.The present model facilitates the study of vertically distributed physical variables in detail.Numerical simulation was conducted according to the transfer process of Kinesia humility meadow in the area of Haibei Alpine Meadow Ecosystem Station,CAS.The calculated results agree well with observation.
