| Abstract: | The varing pattern of heat balance and its divisional quantities in the shelter-belt network was discussed on the basis of observation in Changan village, Raoyang County, Hebei Province. Compared with the wheat feild in open land, the total daily heat input in the work was 3.5% higher, the heat loss through evaparation was 9.9% lower. And the total turbulent heat flux was smaller .Generally, there is the temperature inversion layer in network.The soil heat flux in the network is higher than in the open feild.Provided the heat balance in network is 100%, the heat loss through evaparation accounted for 93%, the soil heat flux-11%, the turbulent heat flux-4% . |
