土壤水对降雨响应过程是水文循环的重要组成部分,研究黄土台塬区的土壤水与降雨之间关系尤为重要。以太原市王家峰村为例,建立了降雨蒸发条件下垂向一维土壤水分运动模型,采用试估-校正法似合参数对模型进行识别验证,分别模拟了四种降雨强度下土壤水分剖面体积含水率和湿润锋的变化规律,揭示了不同降雨强度下黄土台塬区土壤水分再分布过程及动态变化规律,最大限度地提高降水资源利用率,为黄土台塬区水土流失治理提供一定理论依据。
The process of soil water response to rainfall is an important part of the hydrological cycle. It is particularly important to study the relationship between soil water and rainfall in the Loess Plateau. Taking Wangjiafeng Village in Taiyuan City as an example, a vertical one-dimensional soil moisture movement model under rainfall evaporation condition was established. The model was validated by the test-correction method and the parameters were simulated. The water content And wetting front. The redistribution of soil moisture and its dynamic changes under different rainfall intensities were revealed, and the utilization rate of precipitation resources was maximized, which provided a theoretical basis for soil and water loss control in the Loess Plateau.
