Abstract:

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<t³³⁴_0.01=2.568.The developed model will estimate the spatial and temporal value of transpiration from wheat and tree, water uptake by roots of wheat and tree, and soil water content.

Key words: Apple-wheat multiplex system, SPAC, Water transfer model
