摘要
由于不合理灌溉形成的次生盐碱化 ,养分流失 ,以及化学肥料和杀虫剂随土壤水分入渗进入河流和地下水造成水体污染等各种环境问题。迫切地需要量化的溶质运动模型为指导进行研究。本文在分析现有数学模型的物理基础上 ,探讨了此类模型目前需要解决的问题及可能途径。
The secondary salinization due to unreasonable irrigation, the loss of soil nutrients, agrochemical and pesticides infiltrating into soil and finally to groundwater or river may cause pollution, all of above mentioned factors need quantitatively analyzed by solute movement models. The problems involved in physical foundation of solute movement models and their application are discussed, based on which the possible methods and ways are put forward.
