基于SALTMOD模型的灌溉水矿化度对土壤盐分的影响
Effect of Irrigation Water Mineralization on Soil Salinity Based on SALTMOD Model
摘要
Abstract
Taking Shahaoqu irrigation district of Hetao irrigation district as an example,in this paper,the effect of irrigation water salinity on root zone soil salinity was discussed based on SALTMOD model on regional scale.The results showed that root zone soil salinity increased with the increase of irrigation water mineralization,deepening the depth of the drain and increasing canal lining could relieve the effect of high mineralization irrigation water on soil salinity;blending underground brackish water with Yellow River water could effectively control the development of soil salinization.When brackish-fresh water ratio was in 1∶1,root-zone soil was desalinated,the desalination rate was as highest as 23% and above Yellow River water irrigation's 4%.Moderate use of underground brackish water could effectively control groundwater depth and save water resources.关键词
