摘要
对重金属在农田生态系统中的迁移机理进行了详尽介绍,并以此为基础提出一整体数学模型,推导出作物籽实中的重金属含量与灌溉水质、土壤性质、作物根系性质等参数间的定量关系。对陕西交口灌区的农田生态系统也进行了模拟,所得到的模拟值与实测值之间吻合较好。
A mathematical model of heavy metals' transferring in agro-ecosystem was described. In addition, the relationships among irrigating water quality, soil properties, crop root parameters, heavy metal characters, and concentrations of heavy metals in seeds was deduced. Finally, the model was validated at the irrigation district of Jiaokou, Guanzhong area of Shaanxi Province. It has been indicated that the simulating value was well in line with the data from field test.
