土壤中离子交换和运移的模拟研究进展

ADVANCES IN MODELING OF ION EXCHANGE AND TRANSPORT

养分离子由粮区淋失和对植物吸收利用的有效性，以及污染性离子对土壤和地下水资源的潜在性污染等问题要求有效地模拟离子在土壤-水系统中的动态。本文就土壤系统中离子交换和运移模拟模型，参数确定，研究现状等进行简要综述。

Ion transport ln the soil-water system play a significant role in their leaching losses beyond the root zone, availability for uptake by plants, and the potential contamination of groundwater supplies, so effectlve modeling of ion transport ls of considerable value. In this article, a brief summary of exchange model and parameter determination is presented.
