从影响农作物生长的农田水文气象环境因素出发,结合梯田的安全稳定性,土地利用率以及其成本费用等因素,系统全面地分析了不同的梯田田面宽度下各因素的变化规律,最后得出了在黄土高原丘陵区不同的地面坡度下,既保证梯田安全稳定,土地利用率较高,成本费用相对较低,又保证梯田农作物生长环境良好并达到高产稳产的最佳田面宽度。
Based on the hydrological and meteorological environmental factors affecting the crop growth and the factors that affect the safety and stability of terraced fields, land utilization rate and its cost and other factors, we systematically and comprehensively analyzed the variation rules of various factors under the field width of terraced fields. Finally, Under different land gradients in hilly area of the Loess Plateau, it not only guarantees the safety and stability of terraced rice fields, but also has higher land utilization rate, lower cost and relatively lower costs, and ensures the best growth of terraced crops with high and stable yield.
