摘要/Abstract

摘要： In this paper, the importance of investigation on terrestrical processes in arid areas for mankind’s living environment protection and local economy development as well as its present state of the art are elucidated. A coupling model, whichevaluates heat, mass, momentum and radiative fluxes in the SPAC system, is developed for simulating microclimate over plant and bore soil. Especially, it is focussed on the details of turbulence tracsfer. For illustration, numerical simulation of the water-heat exchange processes at Shapotou Observatory, CAS, Ninxia Province areconducted, and the computational results show that the laws of land-surface processesare rather typiical in the arid areas.
