基于HYDRUS-1D模型模拟关中盆地氮在包气带中的迁移转化规律
Migrating and Transforming Rule of Nitrogen in Unsaturated Zone in Guanzhong Basin Based on HYDRUS-1D Model
摘要
Abstract
In this paper, we built soil moisture transform model, the crop root water absorption model and the sol-ute transport model with using HYDRUS-1D software, and then, simulated the transportation and transformation of the nitrogen in unsaturated zone at Guanzhong basin in Shaanxi province. The results indicate:1)The rule of crop root adsorbing water and nitrogen is consistent, and the main absorption of ammonia nitrogen, the absorp-tion rate is 35%;2)the nitrate nitrogen and nitrate are more likely to be leaching into groundwater, and are mainly composed of nitrate nitrogen;3)Different unsaturated zone lithology has a great influence on migration rate and amount of nitrogen.关键词
