摘要
吉林省松嫩平原从补给区到排泄区 ,地下水盐度逐渐增高 ,土壤盐渍化程度逐渐加重。作者采用 3个模型 (区域地下水流系统模型、风化—溶滤模型和蒸发—沉积模型 )来模拟盐渍化的发生发展过程 ,这些模型与区内的地下水运移、土壤岩石的风化和沉积地质过程相一致 ,其中地下水是盐的迁移。
In the Songnen plain,Jilin province,from recharge area to discharge area,the ground water salinity and the degree of soil salinization are gradually increased The three models are developed to imitate the occurrence and development of soil salinization,they are region subsurface flow system model,weathering-leaching model and evaporation-sedimentary model These models are in accordance with ground water migration,weathering of soil,rock and sedimentary facies in the study area,among which,ground water is a main geologic carrier for the migration of salt,gathering and draining
