滴灌条件下土壤水盐运移特性的研究现状

滴灌条件下的水盐运移特性是寻求开发利用盐碱地和次生盐碱化防治的基础 ,国内外学者对此进行大量研究。在国内外研究成果的基础上 ,综述了滴灌点源入渗影响因素、入渗模型特性、水分分布特征、湿润体浸润形状、湿润锋运移、盐分运移的规律 ,为滴灌点源水盐运移的研究提供依据。

Much research of characteristics of soil water and salt transport under drip irrigation, an important basis to develop salt-affected land, has been conducted at home and abroad. In the paper, the related research results about factors affecting point-source infiltration, characteristics of infiltration models and water distribution, shape of wetted zone, wetting front movement and soil salt transport are reviewed in order to provide some informations and opinions to study soil water movement and salt tran...
