| 摘 要： | 根据水量平衡原理和营养物质质量守恒定律，考虑作物生长过程中农田水循环和氮，磷循环特征，建立农田灌溉退水水量水质模型，模拟农田灌溉退水的营养物质浓度，以分析灌溉退水水质的变化幅度。应用该模型对引江济汉工程东荆河灌区农田各水期灌溉退水的氮、磷浓度进行估算，得到与实际情况相一致的数值结果，表明该模型适用于研究农田灌溉退水问题。 |
| 关 键 词： | 农田灌溉退水 灌溉退水水质模型 水循环 东荆河灌区 |

| Abstract: | Based on water balance and conservation law of the nutriment amount, considering hydrologic cycle and nitrogen, phosphorus cycle in farmland, the model of return water quality of farmland irrigation was developed to simulate the concentration of nutriments and analyze the change of return water quality of irrigation. The model is applied to DongJing River irrigation district, and the measured result was accordance with and simulation result. This indicated that the model could be used to predict the return water quality of farmland irrigation. |
| Keywords: | return water of farmland irrigation model of the return water quality~ hydrologic cycle DongJing River irrigation district |
