摘要
根据甘肃省河西走廊疏勒河流域灌区节水灌溉条件下的土壤水盐变化野外和室内实验成果及分析,建立相应的水盐动态模拟数学模型。经过数值模拟计算,得出在一定的灌水方案下的土壤盐分分布状况以及脱盐状况,并对适宜本地区特点的水盐调控措施进行了初步探讨。
According to the outcome and the analysis to the variation of water-salt in soil in the indoor and outdoor experiments, which was made on the condition of the water saving irrigation in Sulehe Irrigated Areas of the Hexi Corridor, Anxi county, Gansu Province, the matched mathematical model of water-salt dynamic simulation was established. After the calculation of the numerical simulation, the distribution of salt and the condition of salt dilution in the case of irrigation are concluded. At the same time, a primary discuss is made on the adjustment measures to local water-salt characteristic.
