Hydrus在农业灌溉及氮素运移方面的研究进展

Research progress of Hydrus in agricultural irrigation and nitrogen transport

我国农业灌溉效率较低,农业水域环境污染问题显著。为了探讨Hydrus在农业灌溉和氮素运移中的应用,文章针对近年来国内外Hydrus在农业灌溉及氮素运移方面的相关文章进行了整理综述。结果表明,Hydrus在涌泉灌溉、滴灌及土壤水分中的应用显著,同时也多用于分析氮素运移的影响因素及硝化与反硝化作用。在此基础上,Hydrus仍存在因模型参数设置等导致的误差,可以通过与其他模型耦合或开发相关拓展功能来提高模拟精度。

The efficiency of agricultural irrigation in China is low,and the problem of environmental pollution in agricultural waters is significant.In order to explore the application of Hydrus in agricultural irrigation and nitrogen transport,this paper summarizes the related articles of Hydrus in agricultural rrigation and nitrogen transport at home and abroad in recent years.The results showed that Hydrus was significantly used in spring irrigation,drip irrigation and soil moisture,and it was also used to analyze the influencing factors of nitrogen transport and nitrification and denitrification.On this basis,Hydrus still has errors caused by the setting of model parameters,so the simulation accuracy can be improved by coupling with other models or developing related expansion functions.
