基于HYDRUS模型不同灌水模式下土壤水盐运移模拟
Study on water and salt transportation of different irrigation modes by the simulation of HYDRUS model
摘要
Abstract
In accordance with the saturated-unsaturated soil water movement and solute transportation theo-ries and based on the field experiments, the transport of soil water and solute of different irrigation modes in Hetao Irrigation District were simulated by HYDRUS-1D/2D model. Characteristics of the water flow and salt transport of different irrigation modes were analyzed. The model has been verified using the data of field experiments. The results show that under the same quota of irrigation,the effect of salt control of fur-row irrigation is better than that of border irrigation. In soil layers of 100cm, the mean value of the soil salt contents in growth stage through furrow irrigation is 24.4% lower than that of border irrigation. Verifica-tion using the experiment data indicates that HYDRUS model has a high precision for the simulation of wa-ter and salt transportation, and the results can serve as a scientific basis for regional water and salt man-agement.关键词
