摘　　要：在土壤－植被－大气统一体内，根据能量平衡、水分平衡、大气辐射传输和热传导方程，建立了一个考虑植被作用的二维地气系统动力模式．模式描述了热量和水分随高度和纬度的变化，并针对陕北地理与气候特征，模拟了该地区的气候平均场，为半干旱地区的沙漠化研究提供了模拟方案和初步计算结果．Based on the equations of energy and moisture balances, radiation transfer and thermodynamics, a 2-dimensional land-air dynamic model with vegetation effect in the entity of soil-vegetation-atmosphere is developed. Variations of heat and moisture with height and latitude are modeled. Taking account of geographic and climate features, the climatic mean fields over the northern part of Shanxi Province are simulated with the model, thereby the simulation scheme for understanding desertification over the semiarid is presented and the preliminary computational results are obtained.
