摘  要:
根据土壤 -植物 -大气连续体 (SPAC)水分传输理论原理 ,充分考虑农林复合系统的特殊性和复杂性 ,建立太行山低山丘陵地苹果 -小麦复合系统SPAC水分运移模拟模型 ,该模型具有二维空间属性。采用数值计算法求解模型方程 ,利用土壤水分实测数据对模型进行验证 ,结果表明 :16 8对模拟值与实测值相对误差的平均值为6 89% ,线性相关系数r可达 0 836 7,t=0 197

摘  要:
Based on the water transfer theories of SPAC, Model on water transfer of SPAC with two spatial dimensions in the apple-wheat multiplex system were developed in the hilly area of Taihang Mountain, which were verified with the experimental data on soil water. The results showed that the estimated value of soil water had good agreement with the measured, and that the linear correlation coefficient(r) between them was 0.836 7(n=168), the average relative error was 6.89%,t=0.197
