| 摘 要： | 对河北平原农田区的As元素在土壤中的输入、输出通量进行了初步研究.综合各方面因素,确定了大气干湿沉降、灌溉水、化肥为输入途径和农作物籽实为输出途径,并进行通量计算.结果显示,在河北平原,大气干湿沉降为土壤中As主要输入方式,灌溉水和化肥输入通量较低,三者对土壤As贡献率分别为53.1%、28.9%和18.1%;而农作物...

| Abstract: | The input and output fluxes of As in farmland soils of the Hebei plain were studied.By integrating various factors,the authors took the atmospheric wet and dry deposition s,irrigation water and fertilizers as As inputs and the seeds of crops as As output for the study.It is indicated that the atmospheric wet and dry deposition is the most important route,while the irrigation and fertilizer fluxes are much lower.These 3 routes have the contributions of 53.1%,28.9% and 18.1% of As in soils,respectively.But th... |
