THE STEADY NUMERICAL COMPARISON OF THE HEAT AND MOISTURE DISTRIBUTION IN A CYLINDRICAL SOIL-BED COVERED WITH PLANTS

ZENG Hai-Bo LIU Wei FAN Ai-Wu(Huazhong University of Science and Technology, Wuhan 430074, China)  
A mathematical modal describing heat and mass transfer in unsaturated porous media is applied. With the consideration of root and crown of the plant, the numerical simulation is made to describe the heat and mass distribution under different environmental conditions in cylindrical vegetation soil-bed on steady state. The simulation is also made to describe the heat and mass distribution under the same environmental conditions between vegetation soil-bed and bare soil-bed. The result is reasonable.
